Elamipretide
SS-31 · MTP-131 · Bendavia · Forzinity
Approved for an ultra-rare mitochondrial disease. Sold in the longevity market for something considerably broader.

29
Registered trials
Tesamorelin
Egrifta
Genuinely FDA-approved — for one specific condition in people with HIV. That approval does not extend to the general anti-aging use it's sold for.

Ibutamoren
MK-677 · MK-0677 · LUM-201 · Nutrobal
A growth-hormone secretagogue, widely mislabelled as a SARM. Studied mostly for growth hormone deficiency rather than the uses it is sold for.

Registered trials
Thymosin α1
Thymalfasin · Zadaxin · Tα1
Genuinely well-studied — 63 registered human trials. But they study hepatitis, cancer and sepsis. None lists an autoimmune condition as its primary indication.
Trials, but not for longevity

Registered trials
Cerebrolysin
Porcine brain peptide preparation
A porcine brain-derived preparation, not a single defined molecule. Studied largely for stroke and dementia rather than cognitive enhancement in healthy people.

Ipamorelin
Growth hormone secretagogue
Both completed human trials studied bowel movement after surgery. Neither studied muscle, fat, or aging.

MOTS-c
Mitochondrial ORF of the 12S rRNA type-c
A mitochondrial-derived peptide with two registered human trials, both in metabolic and kidney disease rather than the endurance uses it is sold for.

GHK-Cu
Copper peptide
One of the few where the trials roughly match the marketing — skin. The hair-growth claims are not what's being tested.

Modified GRF (1-29) · DAC:GRF
One human trial ever registered, and it was stopped early. The registry does not say why.

Sermorelin
GHRH (1-29)
Real research history, mostly in liver and metabolic disease. The anti-aging positioning is a marketing layer on top of that.

Marketed for is not tested for
A compound can be sold for longevity and studied for something else entirely — that is the most common pattern on this site, not the exception. A row saying "trials, but not for longevity" means registered studies exist and none of them asked this question. It is not a claim that the compound does nothing.
