Short chains of amino acids — 3 to 28 residues — that signal specific biological responses. Tissue repair, gut inflammation, immune modulation, neuroplasticity, GH pulse. Compounded by state-licensed U.S. pharmacies and prescribed off-label at provider discretion.
Different peptides solve different problems. Scan the list below by what you're trying to fix, not by the route:
All of the above are sequenced and produced to USP <797> / <800> standards and prescribed only when clinically appropriate after provider review.
Pentadecapeptide from gastric juice. Promotes angiogenesis, tendon & ligament repair, and GI mucosal healing. Sublingual troche, once daily.
GEPPPGKPADDAGLV
Active fragment of Thymosin β4. Actin-binding and systemic soft-tissue recovery — pairs with BPC-157 in the Recovery Stack.
LKKTETQ
28-residue thymic peptide. Modulates T-cell maturation and dendritic-cell activity; used adjunctively in chronic viral infection and post-COVID fatigue.
SDAAVDTSSEITTKDLKEKKEVVEEAEN
Synchronized GHRH analog + ghrelin-receptor secretagogue. Physiologic nighttime GH pulses that support sleep, metabolism, and lean muscle — without the sides of exogenous HGH. Nightly subq.
Modified GHRH (1-29) + 5-aa GHS
Mitochondrial-derived peptide encoded by the 12S rRNA. Activates AMPK, improves insulin sensitivity, and shifts substrate use toward fat oxidation in preclinical work. Studied for metabolic regulation and exercise mimicry.
MRWQEMGYIFYPRKLR
C-terminal fragment of human growth hormone (residues 177–191). Studied for fat metabolism — stimulates lipolysis and inhibits lipogenesis without the glucose-handling effects of full-length HGH. Daily subq.
hGH (177-191) · YLRIVQCRSVEGSCGF
Tetrapeptide from the pineal gland. Upregulates telomerase and restores circadian melatonin rhythm in preclinical + early-human work.
Ala-Glu-Asp-Gly
Russian-developed heptapeptides. Selank reduces anxiety without sedation; Semax boosts BDNF and dopaminergic tone. Intranasal sprays, morning dosing.
TKPRPGP · MEHFPGP
C-terminal α-MSH tripeptide. Downregulates NF-κB and mast-cell activation. Useful in IBD, ulcerative colitis, and topical dermatitis.
Lys-Pro-Val
Copper tripeptide. Remodels skin matrix, activates hair follicle stem cells, and accelerates wound healing. Topical serum or subq micro-dose.
Gly-His-Lys · Cu²⁺
Regulatory note. Peptide therapies listed here are compounded at 503A/503B state-licensed pharmacies and prescribed off-label at provider discretion. None are FDA-approved as finished drugs for the indications described. Full safety profile, sourcing, and contraindications covered at visit intake. See the Safety page for details.
Peptides are short polymers of amino acids — usually 3 to 50 residues — that act as endogenous signaling molecules. Where small-molecule drugs typically saturate a receptor, peptides bind with high specificity and short half-lives, mimicking the body's own pulsed signaling. That's why BPC-157 doesn't behave like an NSAID, and CJC-1295 doesn't behave like exogenous HGH.
Each peptide hits one or two receptor subtypes — minimal off-target.
Short plasma half-lives match physiologic pulses better than depot small molecules.
Provider-prescribed, pharmacy-compounded; not bench-purchased "research-only" vials.
Specific contraindications, sourcing details, and screening requirements are covered at intake.
Safety informationNone of the peptide blends listed here are FDA-approved as finished drugs for the indications described. They are compounded by 503A/503B state-licensed pharmacies and prescribed off-label by your provider when clinically appropriate.
Most peptides are degraded by stomach acid and pancreatic proteases, so oral tablets aren't an option. Sublingual, intranasal, subq, or topical routes preserve the molecule. The ideal route depends on where the peptide needs to act and how stable it is.
Yes — and several stacks are intentional (BPC-157 + TB-500 for recovery; CJC-1295 + Ipamorelin for synchronized GH pulse; Selank + Semax for nootropic effect). Your provider designs the stack and timing at intake.
Active malignancy, certain pregnancies, and some autoimmune conditions are common screening flags. The intake questionnaire surfaces these; your provider reviews before any prescription is issued.
