Which peptides have no registered human trial?

The 25, named

No registered human study names 5-Amino-1MQ, Acetyl octapeptide-3, Adipotide, AOD-9604, Dihexa, DSIP, Epithalon, Follistatin 344, FOXO4-DRI, GHRP-2, GHRP-6, Hexarelin, Humanin, IGF-1 DES, IGF-1 LR3, KPV, MGF, Noopept, Palmitoyl pentapeptide-4, Pinealon, Selank, Semax, Sermorelin, SLU-PP-332 and Thymalin as an intervention.

One entry needs a note. Sermorelin has an FDA-approved product (GEREF) and still appears here: it was approved in 1990, before trial registration was mandatory, so the registry is empty for a reason that has nothing to do with how well it was studied. It is the only compound on this list in that position.

That is a fact about the public record, and it is not the same as proof that any of these does nothing. It means there is no trial evidence to read — so anyone telling you a compound on this list works should be asked for the registration number. Several have laboratory or animal literature; a paper count appears beside each below, and a paper is not a trial.

A study counts only when the compound is named as an intervention in it; the registry search is fuzzy, so every match is re-checked. A search for MGF returned 102 studies of which none administered MGF. Collected 2026-08-02 from ClinicalTrials.gov. How this is put together.
