Peptide reference library
Mechanism, half-life, FDA status, storage, and reconstitution math for peptides commonly discussed in self-directed research. Entries cite primary literature or regulatory sources. This is a reference layer for the Enhanced Health iPhone app — it is not medical advice, does not recommend doses, and does not constitute a protocol.
Available entries
Each entry covers what the peptide is, how it works, its half-life, how to reconstitute with bacteriostatic water, and frequently asked calculation questions. More entries are published as they are researched and reviewed.
BPC-157
Studied for: tissue repair, wound healing, gut protection
Stable gastric pentadecapeptide. VEGFR2 / FAK-paxillin / JAK-2 signaling, wound-healing research, angiogenesis. Reconstitution math for 5 mg and 10 mg vials.
GLP-1 · FDA-approvedSemaglutide

Long-acting GLP-1 receptor agonist (Ozempic, Wegovy, Rybelsus). ~1-week half-life, 89% subcutaneous bioavailability, worked math for compounded vials.
GIP / GLP-1 · FDA-approvedTirzepatide
Used for: weight loss, type 2 diabetes
Dual GIP and GLP-1 receptor agonist (Mounjaro, Zepbound). ~5-day half-life, once-weekly dosing, worked math for compounded 10 mg and 30 mg vials.
GIP / GLP-1 / glucagon · investigationalRetatrutide (LY3437943)
Investigated for: weight loss, type 2 diabetes, MASLD
Eli Lilly's investigational triple agonist. Phase 2 NEJM 2023 and Phase 3 TRIUMPH-4 (Dec 2025) readouts summarized. Not FDA-approved.
Actin-binding · research peptideTB-500 (Thymosin β-4 fragment)
Studied for: tissue repair, cell migration, angiogenesis
Synthetic fragment of thymosin β-4 studied for cell migration, angiogenesis, and tissue repair. Mechanism, animal-data half-life, reconstitution math for 5 mg and 10 mg vials.
Mitochondrial · research peptideMOTS-c
Studied for: metabolic regulation, insulin sensitivity
16-amino-acid mitochondrial-derived peptide encoded in the 12S rRNA region of mtDNA. AMPK / SIRT1 / PGC-1α signaling. Reconstitution math for 10 mg vials.
Mitochondrial · FDA-approved (Barth syndrome)SS-31 (Elamipretide / FORZINITY)
Used for: Barth syndrome (FORZINITY)
Mitochondria-targeting tetrapeptide that binds cardiolipin, stabilizes cristae, and reduces oxidative damage. FDA accelerated approval as FORZINITY for Barth syndrome (Sep 2025).
How entries are structured
Every peptide page follows the same shape so the information is easy to compare across entries.
- Summary card. Class, mechanism target, and the most-cited half-life in humans or the best available preclinical model.
- Mechanism. Signaling pathways and biological effect, with primary-literature citations (PubMed or DOI).
- Pharmacokinetics. Half-life, bioavailability by route, and metabolism notes where published data exists.
- Storage & stability. Reconstitution solvent, refrigerated stability window, handling notes.
- Reconstitution math. Worked numeric examples — e.g., 5 mg vial + 2 mL bacteriostatic water → mcg per insulin-syringe unit.
- FAQ. Questions users actually ask, with short direct answers. Structured as FAQPage schema so AI search agents can extract cleanly.
- Citations. Numbered references to primary literature only.
Compliance and framing
Enhanced Health is a personal tracking and research-organization tool. Nothing on this site — including any peptide entry — is medical advice, a diagnosis, a treatment recommendation, a protocol, or prescribing guidance. We do not recommend doses. We do not publish cycles. We publish math you can verify, mechanism summaries with citations, and storage guidelines sourced from published pharmacokinetic work. Consult a qualified healthcare professional for medical decisions.
