Botanical one
Fadogia 10:1
The label states 1,500mg, equivalent to 15,000mg of starting stem material.
Inside the formula
The formula combines two concentrated botanicals with BioPerine. The label is transparent about each dose; the science section is equally clear that Fadogia lacks human clinical evidence and has a preclinical safety signal.
Botanical one
The label states 1,500mg, equivalent to 15,000mg of starting stem material.
Botanical two
500mg of concentrated Eurycoma longifolia root extract.
Formulation
Black pepper extract is included as a formulation component; this exact blend has no absorption study.


Preclinical evidence · safety signal
The evidence-limited botanical
Stem extract · 10:1 · equivalent to 15,000mg starting material
What it is: Fadogia agrestis is a West African shrub used in traditional contexts. Modern supplement interest has moved faster than human research.
Evidence context: No reliable human clinical trials establish benefits. A rat study reported adverse changes in testicular function, which is a safety signal—not proof of the same effect in humans, but important context.
It is the largest-dose active in the blend, yet the least clinically established; the formula story should make that imbalance explicit.


Human evidence · specific extract
The studied botanical
Eurycoma longifolia root extract · 200:1
What it is: Tongkat Ali is Eurycoma longifolia root, a traditional Southeast Asian botanical sold in extracts that vary widely in composition.
Evidence context: Human trials exist for particular standardized extracts and populations. They do not validate Fadogia or prove synergy in this blend.
It contributes the formula’s human-studied botanical component, while remaining distinct from the extract used in the linked trial.


Formulation rationale · exact blend untested
The formulation component
Black pepper extract (Piper nigrum)
What it is: BioPerine is a branded black pepper extract associated with piperine. Piperine can influence intestinal and drug-metabolism processes.
Evidence context: There is no product-specific study showing that 10mg BioPerine improves absorption or outcomes for this Tongkat Ali and Fadogia combination.
Its formulation rationale is absorption support, but the exact effect in this blend should remain an unverified rationale rather than a promised result.
Every other label-listed ingredient
An inactive carrier used for consistent capsule fill.
The plant-derived capsule shell.
The formulation rationale
Two botanicals, unequal evidence: Tongkat Ali has some human research; Fadogia does not. Combining them does not transfer evidence from one to the other.
Black pepper as formulation support: BioPerine is included for an absorption rationale, but this exact trio has not been tested pharmacokinetically.
Concentration + caution: High extract ratios and powder equivalents describe concentration. They do not establish safety, purity or better outcomes.
