We score every product on one public scale — what is in it, at what dose, what buyers actually report, and what a serving costs. Brands can buy a labelled slot on this site. Not a single one has ever been able to buy a rank.
Pick a product and we line up every active ingredient against the dose used in published trials. Under, at, or over — no interpretation needed. In the testosterone category, most products fail on the first ingredient.

The offer is $4.95 and the charge is $89.61 a month later. The free-trial billing trap taken apart step by step, and how to spot it before you hand over a card.

Researchers put 50 of these products through the literature. Three in five ingredients had no published data at all. Two survive the check, with conditions.

One calculation across all 27 products in our rankings. The spread runs to nineteen-fold, and for six of them the sum cannot be done at all.
