RESEARCH PEPTIDES

Understand the research before the hype.

AEVLI separates approved medicines, investigational therapeutics and experimental compounds. Each profile shows what researchers are studying, what has actually been tested in humans and where uncertainty remains.

Evidence first

Research status varies dramatically. Tesamorelin and bremelanotide have specific FDA-approved uses; retatrutide is a late-stage investigational medicine; compounds such as BPC-157 and TB-500 remain unapproved research compounds. AEVLI does not provide sourcing, dosing, reconstitution or administration instructions.

Research compound

BPC-157

A widely discussed experimental peptide with an extensive preclinical literature but very limited clinical evidence.

Investigational medicine

Retatrutide

A triple GIP, GLP-1 and glucagon receptor agonist in late-stage clinical development for obesity and metabolic disease.

Read evidence profile →
FDA-approved medicine for a specific indication

Tesamorelin

A GHRH analogue with a genuine approved medical use and randomized human evidence—important context when it appears in broader peptide discussions.

GHRH analogue / historical clinical use

Sermorelin

The 1–29 fragment of GHRH, with established human GH-stimulation pharmacology but a different evidence profile from modern approved GH-axis medicines.

FDA-approved medicine for a specific indication

PT-141 / Bremelanotide

A melanocortin receptor agonist where an internet “peptide” name overlaps with an FDA-approved prescription active ingredient.

Read evidence profile →
Unapproved research compound

Melanotan II

A synthetic melanocortin analogue widely discussed for tanning, but without an approved medical tanning indication and with significant evidence and product-quality concerns.

Read evidence profile →
Immunomodulatory peptide; regulatory status varies internationally

Thymosin alpha-1

A peptide with a substantial international clinical literature, but mixed results across indications and no basis for broad “immune boosting” claims.

Read evidence profile →
Experimental host-defense peptide

LL-37

A human cathelicidin peptide with antimicrobial and wound-healing biology plus early controlled topical human trials.

Read evidence profile →
Experimental neuropeptide

DSIP

A historically studied “delta sleep-inducing peptide” whose name is more confident than the inconsistent human sleep evidence warrants.

Read evidence profile →
Endogenous reproductive peptide / investigational therapeutic pathway

Kisspeptin

A central regulator of human reproductive hormone signalling with a serious and expanding clinical research program.

AEVLI EDITORIAL STANDARD

Interesting research, without turning uncertainty into a promise.

Profiles distinguish mechanism from outcomes, preclinical findings from human evidence, and pharmaceutical approvals from similarly named research-market products.
