testosterone vs hgh

updated October 25, 2026

testosterone (tier S) vs hgh (tier S): what each is, why each got its grade, half-life and source counts side by side.

testosterone · tier S

the male sex hormone. the approved products replace it in men whose own production has failed, and above that range the same molecule adds muscle and strength with no training at all. schedule iii controlled substance in the us. educational record only, not medical advice.

tier rationale

S-tier because the bar for S is drug-grade human evidence, and testosterone clears it by a wider margin than anything else on the board. FDA-approved products across six routes, a 5,246-participant randomised cardiovascular outcomes trial, an Endocrine Society guideline built on two commissioned systematic reviews, and ninety years of clinical use. A-tier is for a strong mechanism with a missing approval, and testosterone has the approval. The grade measures the evidence and stops there. It says nothing about whether anyone should research the compound, about supraphysiologic exposure, or about any way of obtaining it, and this is the only S-tier entry that is also a federally controlled substance carrying the worst analytical record on the board.

hgh · tier S

growth hormone. banned in sports, standard at every anti-aging clinic, expensive. works, with trade-offs.

tier rationale

the original anabolic peptide drug. 40+ years of FDA approval across 11+ brand names for pediatric growth failure, adult GHD, HIV wasting, and short bowel syndrome. massive evidence base. criminalized for non-approved uses. one of the most regulated peptides in existence. four decades of pivotal trial evidence. S is the only defensible tier.
