The name is a claim, and it mostly holds. Our plain read on how transparent they are about doses and testing — and what their products actually scored.
A brand that named itself after the thing this category is worst at has set itself a test in public. On labelling, it largely passes.
Fully-disclosed formulas, no proprietary blends, per-ingredient doses stated. That is the whole positioning and the company sticks to it, which makes their products easy for us to rate — we can check every dose against the research without having to write "undisclosed" anywhere.
Disclosing a dose is not the same as choosing a good one. In the testosterone category specifically, a fully-transparent label can still be a list of ingredients whose evidence is thin — and no amount of honest labelling turns an ingredient with mixed human data into one that works. Read the ingredient index alongside the label.
Prices are premium, and the formulas are often long — many ingredients at real doses adds up to a big capsule count and a big monthly cost. A shorter formula of the two or three ingredients with the best evidence would usually serve the buyer better than a comprehensive one.
