Longevity Peptides

Healthspan, mitochondrial, and immune compounds, separated by whether the data is human or rodent.

Thymosin Alpha-1

longevity & healthspanAgrade

A 28-amino-acid thymic peptide approved in 35+ countries as Zadaxin for immune support — but never FDA-approved in the United States.

Oxytocin

longevity & healthspanBgrade

A naturally occurring nonapeptide — FDA-approved as Pitocin for labor, and separately studied off-label (intranasal) for social bonding and stress research.

SS-31 (Elamipretide)

longevity & healthspanBgrade

A mitochondria-targeting tetrapeptide, FDA-approved in September 2025 for Barth syndrome — a real approval in one narrow rare disease, not a general muscle or longevity drug.

Humanin

longevity & healthspanCgrade

A mitochondrial-derived peptide discovered protecting neurons from Alzheimer's-linked toxicity — cell and rodent data only, no human trial exists.

MOTS-c

longevity & healthspanCgrade

A mitochondrial-derived peptide that supports metabolic flexibility, insulin sensitivity, and exercise capacity.

VIP (Vasoactive Intestinal Peptide)

longevity & healthspanCgrade

A 28-amino-acid neuropeptide with broad vasodilator, anti-inflammatory, and immunomodulatory effects, cleared from plasma within about a minute.

Epithalon

longevity & healthspanDgrade

A synthetic tetrapeptide analog of a natural pineal gland peptide, studied for telomerase activation and circadian regulation.

SLU-PP-332

longevity & healthspanDgrade

A pan-ERR agonist nicknamed the 'exercise pill' — reduced fat mass and raised fatty-acid oxidation in obese mice, with zero human trials as of 2026.

SLU-PP-915

longevity & healthspanDgrade

The first orally-active pan-ERR agonist — raised exercise capacity in mice even when dosed orally, where its predecessor SLU-PP-332 needed injection.

Adamax

longevity & brainFgrade

A synthetic nonapeptide analog of Semax with N-terminal acetylation and adamantyl C-terminal modification, studied for enhanced BDNF signaling and blood-brain barrier penetration.

Pinealon

longevity & healthspanFgrade

A Khavinson-group tripeptide bioregulator, studied preclinically for neuroprotective and cognitive-aging effects.
