- All nine ErecPower ingredients broken down individually.
- Zinc and Tongkat Ali: strongest evidence.
- Tribulus, chrysin and winged treebine: thinnest evidence.
Strongest evidence
Tongkat Ali raised total testosterone in a 2022 meta-analysis, most clearly in men who started low. Zinc raises testosterone when correcting a deficiency.
Mixed or early evidence
Magnesium is essential but not proven to boost vitality in men who already get enough. Epimedium shows lab effects on blood-flow pathways with limited human data. Saw palmetto and hawthorn both have large but mixed research literatures.
Weak or thin evidence
A 2025 review found no robust testosterone effect for Tribulus. Chrysin is poorly absorbed. Winged treebine is traditional with thin human data.
The missing milligrams
None of the nine ingredients has a published amount on the label — evidence on an ingredient is not evidence about a finished product at an unknown dose.
FAQ
Which ingredient is weakest in evidence?
Tribulus Terrestris, with a 2025 review finding no robust testosterone effect.
Does evidence on an ingredient prove the product works?
No. Evidence applies to the ingredient studied at a specific dose, not necessarily to the finished product at an undisclosed amount.
