Historical Phase 2 obesity-development program; no approved product followed.
AOD-9604 · Phase 2 (historical) · Historical clinical development
AOD-9604 advanced into human obesity development through Phase 2-era studies, but the obesity program did not establish the efficacy needed to become an approved treatment and did not progress to approval.

Limited exploratory human evidence; no validated late-stage therapeutic program identified.
BPC-157 · Exploratory human evidence · No established development program
BPC-157 has very limited reported human exposure, but there is no established modern clinical-development program demonstrating progression through conventional Phase 1, 2, and 3 milestones.

Small double-blind insomnia studies reported weak or inconsistent clinical effects.
DSIP · Early human studies (historical) · Historical clinical development
DSIP was tested in small controlled human sleep studies decades ago, but the work predates a modern late-stage drug-development program and did not produce an approved therapy.

No established modern Phase 1–3 therapeutic program identified.
Epitalon · Preclinical / no established modern program · No established development program
Modern evidence for epitalon is dominated by laboratory, cell, and mechanistic work rather than a validated contemporary clinical-development pathway leading toward regulatory approval.

Small randomized topical study after CO2 laser resurfacing.
GHK-Cu · Early human evidence — topical route · No established development program
GHK-Cu has small human studies in topical/cosmetic contexts, but that route-limited evidence does not establish an injectable clinical-development program.

No established direct human therapeutic development milestone identified.
IGF-1 LR3 · Preclinical / no established human program · No established development program
IGF-1 LR3 is discussed widely in research and performance communities, but a peer-reviewed clinical-development program for the exact analogue has not been established.

Human biology is documented; no established approved or late-stage therapeutic program identified.
MOTS-C · Preclinical / human biology evidence · No established development program
MOTS-C has substantial interest as an endogenous mitochondrial-derived peptide, but human biology measurements are not the same as a validated therapeutic development program using administered MOTS-C.

Pilot Phase 1 human study demonstrated tanning activity and dose-limiting adverse effects.
MT2 / Melanotan II · Phase 1 (historical) · Historical clinical development
Melanotan II was studied in a pilot Phase 1 human program and later small controlled sexual-function studies, but it did not become an FDA-approved tanning or sexual-function medication.

No established direct human therapeutic development milestone identified.
PEG-MGF · Preclinical / no established human program · No established development program
PEG-MGF does not have an established peer-reviewed human clinical-development program. Findings involving native MGF or IGF-1 biology should not be transferred automatically to PEG-MGF.
