Disclosure: Eternal Elixir makes supplements, and our own product sits first in this comparison. Eternal Elixir makes Tongkat Ali 200:1 Extract 2000mg, and it is our pick. Every figure for the other five products comes from their own product pages and labels, read in September 2026, and every study figure comes from the published paper. No brand paid to be included. Here is how we write and review content.

Best turkesterone supplements 2026: the six compared

Prices are one-bottle prices from each seller’s own product page as of Sep 2026. Declared turkesterone is the number of milligrams of turkesterone the label commits to per capsule. It is not the weight of the Ajuga turkestanica extract, which is a larger and much less useful number. Cost per capsule is the bottle price divided by the capsule count.

Four of the five turkesterone products commit to a turkesterone figure on the label or product page, and one of them (Double Wood) shows a lab result for a specific lot. The cheapest turkesterone per declared milligram is Nutricost, and the most expensive is HTLT, which declares 10 mg per capsule at $2.00 a capsule.

What the human research on turkesterone found

Turkesterone is a phytoecdysteroid, a steroid-shaped compound from the herb Ajuga turkestanica. Its muscle-building reputation comes from animal work. A 1976 study cited by a later human trial gave castrated rats 0.5 mg/kg of turkesterone and other ecdysteroids daily for 10 days and reported gains in muscle mass and protein content. People are a different matter. Two controlled human studies exist, both from 2024, and both came back null.

Neither study put people through a supervised training program, and the longest lasted four weeks. So the accurate summary is that turkesterone has not been shown to work in humans, not that it has been proven useless. The Antonio authors list possible reasons for the null result: absorption in humans is unclear, it may not interact with human receptors the way it does in animal models, and placebo effects may explain some of the online reports.

Most of the stronger-sounding data belong to ecdysterone (20-hydroxyecdysone), a related compound. One 10-week trial in 46 young men found larger muscle and bench press gains with ecdysterone (Isenmann et al., 2019), while an 8-week trial in 45 resistance-trained men at 200 mg a day found no effect on fat-free mass, strength or testosterone (Wilborn et al., 2006). A result for ecdysterone does not carry over to turkesterone. Our turkesterone vs creatine guide lays out every trial, and our turkesterone side effects guide covers the safety data.

Evidence level: muscle gains in rats, none shown in two small human studies. If you are after hormone support rather than an ecdysteroid specifically, our comparison of natural testosterone boosters covers botanicals with more human data.

How we ranked these turkesterone supplements

We did not run our own lab tests. We read every live product page and label, recorded what each one commits to, checked whether a lot-specific lab result is published, and priced each bottle in the same week. The five turkesterones are ordered on four things:

• Published lot testing: does the seller show a lab result for turkesterone itself, for a named lot?
• Declared turkesterone: does the label state a turkesterone percentage or milligram figure, or only an extract weight?
• Cost per declared milligram: bottle price divided by the total turkesterone the label declares.
• Label clarity: is the serving, capsule count and full ingredient list stated where a buyer can read it?

Eternal Elixir makes Tongkat Ali 200:1 Extract 2000mg, and it sits first as our in-stock pick while our Turkesterone 500mg is sold out. The reasons are set out in its entry, including the case against it. We apply the same approach of checking trial doses against label doses across categories in our supplement dose gap report.

1. Eternal Elixir Tongkat Ali 200:1 Extract 2000mg: our in-stock pick

Eternal Elixir Tongkat Ali 200:1 Extract 2000mg is our own product and our pick, and it contains no turkesterone. Our Turkesterone 500mg (500 mg of Ajuga turkestanica extract per capsule, 60 capsules) is sold out, so we point turkesterone shoppers to the in-stock product in our range that serves the same goal.

The case for it: tongkat ali (Eurycoma longifolia) has randomized human trials on the outcome most turkesterone buyers care about. A 2022 meta-analysis pooled five randomized trials and found higher total testosterone in men taking tongkat ali (Leisegang et al., 2022). No human study has measured testosterone after turkesterone at all. Each 3-capsule serving of ours supplies 2,000 mg of 200:1 root extract, and the label names the species, the plant part and the extract ratio.

The case against it: it is not an ecdysteroid, so if you specifically want turkesterone, the five entries below are your options. The trials in that meta-analysis used specific standardized extracts, and our product page says this exact 200:1 product has not been clinically tested. The 200:1 figure describes concentration, not purity. Our page also notes that tongkat ali may affect hormones and can interact with health conditions or medicines, so talk to your doctor before using it if you take prescription medicines.

Key specs: 90 capsules, 2,000 mg Eurycoma longifolia root extract (200:1) per 3-capsule serving, 30 servings, rice flour and cellulose capsule as the only other ingredients.

• Who it suits: buyers whose real goal is training and male hormone support, and who would rather take the botanical with more human trials behind it.
• Who it doesn’t suit: anyone set on an ecdysteroid, and anyone who wants a single capsule a day (the serving is three).

Price: $29.99 for 90 capsules, or $1.00 per 3-capsule serving. Our range also covers Tongkat Ali + Fadogia, Shilajit 1000mg and Korean Panax Ginseng, so a training stack can ship in one order. Our tongkat ali supplement comparison sets our label beside other US brands.

2. Double Wood Turkesterone 10%: best verified potency

Double Wood Supplements does one thing no other brand here does. Its product page shows a lot certificate with a measured turkesterone result. For lot 2530800 (manufactured 12/2025, lab listed as Brand Nutraceuticals, Inc.), the certificate reports 53.5 mg of turkesterone per capsule against a claim range of 45 to 62.5 mg, and 535 mg of Ajuga turkestanica against a 450 to 625 mg range. Lead came in at 0.097 µg per serving against a 0.5 µg limit, and the microbial tests passed.

Double Wood turkesterone is also the product used in the 11-man Harris trial, which is as close as any brand here gets to human data, even though that trial found no effect. The facts panel lists one capsule (500 mg of whole-plant Ajuga turkestanica, 10% turkesterones, 50 mg) as a serving, and the label directions say to take two capsules a day. The web page says one or two capsules with a meal, and not more than four a day. We cover the brand in our Double Wood Supplements review.

• Who it suits: buyers who want a lab number for the lot rather than a percentage on a label.
• Who it doesn’t suit: anyone who wants a small first bottle. At 120 capsules it is a bigger commitment in a category with thin evidence.

Key specs: 120 capsules, 50 mg declared turkesterone per capsule, 4.75 out of 5 from 20 reviews on the product page, free shipping on orders of $30 or more (Sep 2026).

Price: $39.95 for 120 capsules direct from Double Wood, or $0.33 a capsule and $0.67 a day at two capsules.

3. Nutricost Turkesterone: best value per declared milligram

Nutricost declares the most turkesterone per capsule of any product here, at the lowest price per capsule. Its supplement facts panel lists one capsule as a serving, with 600 mg of whole-herb Ajuga turkestanica extract standardized to 10% turkesterone, which is 60 mg. The 120-capsule bottle costs $38.97, so the cost is $0.32 per capsule and about $0.05 per 10 mg of declared turkesterone. A 30-capsule bottle is $17.97 ($0.60 a capsule) if you want a smaller trial.

The product page says each batch is tested by independent, ISO-accredited laboratories. We did not find a published turkesterone result for a specific lot on the product page, which is the one thing that keeps it behind Double Wood. Our Nutricost review covers the brand’s wider range, and Nutricost also appears in our Fadogia agrestis supplement comparison.

• Who it suits: buyers who want the most declared turkesterone for the money, with a small-bottle option.
• Who it doesn’t suit: buyers who want to see a lab result before they buy.

Key specs: 120 or 30 capsules, 60 mg declared turkesterone per capsule, one capsule per serving, hypromellose capsule.

Price: $38.97 for 120 capsules direct from Nutricost, or $0.32 a capsule.

4. eFlow Nutrition Turkesterone: pick for a cyclodextrin formula

eFlow Nutrition pairs its extract with hydroxypropyl-beta-cyclodextrin, a carrier molecule the label lists as a complex with the extract. The supplement facts panel gives one capsule as a serving, 60 servings, and 500 mg of Ajuga turkestanica extract standardized to 10% turkesterone (50 mg). The directions on the product page say to take one capsule twice daily, and the page suggests a 90-day period.

The product page says the cyclodextrin complex is there for increased absorption, but it does not publish absorption data, and no human study has tested cyclodextrin-complexed turkesterone. At $59.99 for 60 capsules, it costs $1.00 a capsule, or $2.00 a day at the directed two capsules. That is about $0.20 per 10 mg of declared turkesterone, four times Nutricost’s figure. The page showed 4.89 out of 5 from 141 reviews when we checked in September 2026.

• Who it suits: buyers who want a turkesterone percentage on the label and are curious about a cyclodextrin carrier.
• Who it doesn’t suit: price-conscious buyers, since a month at the directed dose costs about $60.

Price: $59.99 for 60 capsules direct from eFlow (listed down from $69.99).

5. HTLT Turk Builder Max: best for a full-spectrum Ajuga blend

HTLT takes a different approach from the rest of the field. Instead of a high-milligram extract, Turk Builder Max declares 10 mg of turkesterone, 10 mg of ecdysterone and 4 mg of minor ecdysteroids per capsule, from an Ajuga turkestanica extract that the brand says is made in Uzbekistan, plus a Rhodiola heterodonta extract. The capsules come in blister packs of 40.

The product page links an HPLC test and a folder of batch reports, which puts it ahead of brands that publish nothing. The directions say to start with one capsule to check tolerance, take one to three on training days, and not exceed three a day, and they advise against taking it after 4pm because it may affect sleep. The cost is the catch. At $79.99 for 40 capsules, one capsule costs $2.00, which works out to $2.00 per 10 mg of declared turkesterone, ten times what eFlow charges for the same amount.

• Who it suits: buyers who want a mixed ecdysteroid profile with lab reports and don’t mind paying for it.
• Who it doesn’t suit: anyone comparing on cost, and anyone who wants a single-ingredient product (the rhodiola adds a second active).

Price: $79.99 for a 40-capsule pack direct from HTLT.

6. Huge Turkesterone: pick for an ecdysterone-standardized formula

Huge Supplements sells its turkesterone as a 500 mg Ajuga turkestanica extract in a hydroxypropyl-beta-cyclodextrin complex. The product page calls the capsules soft gels. The supplement facts panel lists a gelatin capsule, one per serving, 60 servings, and a standardization to 10% ecdysterones rather than to turkesterone. So the label does not commit to a turkesterone figure at all, which is why it ranks last among the turkesterones here.

The directions are one capsule in the morning with a meal on training and rest days, with two or three a day for what the page calls advanced users. It suggests cycles of 8 to 12 weeks with a two-week break. We found no third-party test or lot result on the product page. At $49.95 for 60 capsules, the cost is $0.83 a capsule, and free US shipping starts at $100.

• Who it suits: buyers who are comfortable with an ecdysteroid blend and like the idea of a cyclodextrin carrier.
• Who it doesn’t suit: anyone who wants a declared turkesterone amount, since the label gives none.

Price: $49.95 for 60 capsules direct from Huge Supplements.

Cost per day at each label’s directions

Cost per capsule hides how many capsules each brand tells you to take. This is the daily cost at each label’s own directions, using the one-bottle prices above (Sep 2026).

On this measure Nutricost is the cheapest turkesterone to run. eFlow costs about six times as much per day for 100 mg of declared turkesterone, and HTLT costs at least six times as much for 10 to 30 mg. None of these doses has been tested in a training trial.

How to check a turkesterone label before you buy

1. Find the percentage. “10% turkesterone” on a 500 mg extract means 50 mg. An extract weight with no percentage tells you nothing about turkesterone content.
2. Check which compound is standardized. Some labels standardize to ecdysterones rather than turkesterone, as Huge’s does. That is a different molecule.
3. Look for a lot result. A certificate that names a lot number and reports measured turkesterone is worth more than a percentage alone.
4. Do the daily maths. Multiply the cost per capsule by the capsules the directions call for.
5. Set an end date. The longest human study lasted four weeks, so decide in advance how long you will take it and what would count as a result.

Extract milligrams are not turkesterone milligrams

When a label says “Turkesterone 600 mg,” it almost always means 600 mg of Ajuga turkestanica extract, of which turkesterone is a fraction. A 500 mg capsule standardized to 10% delivers 50 mg of the compound. An unstandardized capsule delivers an unknown amount, whatever the front of the bottle says.

Lab testing shows the gap is real. A 2026 LC-MS analysis tested 13 ecdysteroid supplements, including four Ajuga turkestanica extracts labeled as 10% turkesterone (Todorova et al., 2026):

Only one of the four met its claim. One held about 1% of its expected turkesterone but about 25 mg of ecdysterone. The paper does not name the brands, so none of these rows can be matched to the products in our list. The problem is wider than turkesterone. A 2020 analysis of 12 ecdysterone supplements found content generally much lower than labeled (Ambrosio et al., 2020), and in a 2025 training trial the study capsules held under 1% of their labeled ecdysterone (Dissemond et al., 2025).

The practical rule: treat an extract weight with no percentage as a description of plant powder, and give the most weight to a lot result that measures turkesterone by HPLC or LC-MS. The same extract-versus-active problem shows up with tongkat ali, where the useful number is the extract ratio or marker compound, as our tongkat ali roundup explains.

Why brands are leaving the turkesterone category

Turkesterone was a fitness-marketing craze a few years ago. Several brands have since stepped back, and we checked three examples in September 2026:

• Gorilla Mind: its old turkesterone product URL redirects to a Turk-Plex URL, which in turn redirects to the homepage, and its current store catalog of 53 products has no turkesterone.
• Toniiq: its turkesterone product URLs return a “not found” page, and its store catalog of 104 products has no turkesterone, even though search summaries still recommend it.
• Herbal Bee: the brand’s own domain now redirects to a domain-sale listing.

None of that proves turkesterone does nothing. It does mean a brand still selling it should be held to a higher proof standard, and a lot certificate is the minimum. If you want a compound with a longer human research record, our guides to the best supplements for men over 40 and the best shilajit supplements cover better-studied options.

Tongkat ali or turkesterone: which has better evidence?

For hormone support, tongkat ali has the stronger human record. The 2022 meta-analysis pooled five randomized trials measuring total testosterone in men (Leisegang et al., 2022). Turkesterone’s two human studies measured IGF-1, metabolism and body composition, and neither measured testosterone. The ecdysterone trials that did measure hormones found no change in testosterone (Wilborn et al., 2006, and Denben et al., 2023).

For muscle growth, neither has the evidence of creatine monohydrate, which added 1.10 kg more lean mass alongside resistance training in a meta-analysis of 35 randomized trials (Delpino et al., 2022). We don’t sell creatine, and we would still put it first for a lifter building a routine from scratch.

If you want to add a botanical from our range once the basics are in place, these three are in stock. Read our Fadogia agrestis guide before the blend, since our product page states that fadogia lacks human clinical evidence and has a preclinical safety signal. Our guides to shilajit for men and ginseng for men cover the other options.

Frequently asked questions about the best turkesterone supplements

Which brand of turkesterone is best?

Eternal Elixir is our pick, with a caveat: our Turkesterone 500mg is sold out, so our in-stock pick is Eternal Elixir Tongkat Ali 200:1, which is not a turkesterone. If you want turkesterone itself, look for a brand that shows a lot result. Double Wood Turkesterone 10% publishes one (53.5 mg per capsule for lot 2530800), and Nutricost declares the most turkesterone per dollar at 60 mg for $0.32 a capsule.

Does turkesterone actually raise testosterone?

There is no evidence that it does. No human study has measured testosterone after turkesterone, and the ecdysterone trials that measured hormones found no change in testosterone. Turkesterone is not thought to act on the androgen receptor that testosterone uses.

What’s better, Tongkat Ali or turkesterone?

For hormone support, tongkat ali has the better evidence. A 2022 meta-analysis pooled five randomized trials and found higher total testosterone in men taking it, while turkesterone has no human testosterone data. The trials used specific standardized tongkat extracts, so results depend on the product.

How long until turkesterone kicks in?

No human study has shown an effect at any point, so there is no evidence-based timeline. The longest trial ran four weeks at 500 mg a day and found no change in body composition. Brands suggest cycles of 8 to 12 weeks (Huge) or a 90-day period (eFlow), but those are marketing conventions, not trial results.

Does turkesterone really work for muscle growth?

Not on current human evidence. Single doses of 1,000 mg and 2,000 mg did not significantly raise IGF-1 in 11 men, and 500 mg a day for four weeks did not change lean mass in 31 active adults. The muscle gains in the research come from rats.

Is turkesterone a steroid?

Chemically it has a steroid backbone, which is where the “sterone” comes from. It is a plant ecdysteroid, not an anabolic androgenic steroid, and in cell and animal research ecdysteroids appear to work through an estrogen receptor rather than the androgen receptor (Parr et al., 2014).

How much turkesterone should I take?

No effective dose has been established. The human studies used 500 mg of extract a day and single doses of 1,000 mg and 2,000 mg, and the Harris authors note that most labels recommend 1,000 mg a day and advise against going past 2,000 mg. Follow the label of the product you buy, and set an end date.

Is turkesterone safe?

The short-term data look clean but thin. Single doses up to 2,000 mg did not significantly change stomach symptoms, heart rate or blood pressure in 11 men, and the four-week trial did not report adverse events. No study has run longer or measured liver markers. Talk to your doctor first if you take prescription medicines, have a liver or kidney condition, or are pregnant, breastfeeding or under 18.

What happened to Gorilla Mind turkesterone?

It is no longer listed. In September 2026, Gorilla Mind’s old turkesterone URL redirected through a Turk-Plex URL to the homepage, and its store catalog had no turkesterone product. The brand has not published a reason that we could find.

Verdict: which turkesterone supplement should you buy?

Our pick: Eternal Elixir Tongkat Ali 200:1 Extract 2000mg, $29.99 for 90 capsules. Our Turkesterone 500mg is sold out, and this is our in-stock pick for the same goal: a botanical with randomized human trials on testosterone, 2,000 mg of 200:1 extract per 3-capsule serving.

If you want turkesterone with proof of what is in the capsule: Double Wood Turkesterone 10%, $39.95 for 120 capsules, the only product here with a published lot assay of turkesterone.

If you want the most declared turkesterone for the money: Nutricost Turkesterone, $38.97 for 120 capsules of 60 mg each.

If you are not sure turkesterone is worth it: that is a reasonable reading of two null human studies and a category with proven label gaps. Creatine monohydrate is the better-supported first step for training, and our turkesterone vs creatine comparison shows the numbers.
