What it is
Tongkat Ali is the common name for Eurycoma longifolia, a Southeast Asian botanical used traditionally in male vitality contexts.
What research suggests
A 2022 systematic review and meta-analysis reported a significant increase in total testosterone across included studies, with authors describing Eurycoma longifolia as a possible option while also stating that more research is needed before clinical use. Study quality, extracts and populations vary.
How VigorPeak labels it
The seller lists 10 mg of a 100:1 Tongkat Ali extract and describes that as roughly equivalent to 1,000 mg dried root. That equivalence is a material-equivalent statement, not a direct comparison with a clinical trial dose unless the extracts are actually comparable.
What not to claim
It is not responsible to say that the presence of Tongkat Ali proves VigorPeak will correct low testosterone, treat erectile dysfunction or produce a specific testosterone increase.
