Peptide Map
A structured visual index of 38 peptides organized along two axes: mechanism family across the top, and regulatory status from FDA-approved at the top to research-only at the bottom. Hover any cell for a quick read; click for the full editorial guide.
The map borrows its structure from the periodic table of elements. Position carries information: a peptide's column tells you what it does, its row tells you whether it can be lawfully obtained in the United States, and its symbol is a short element-style abbreviation. Empty cells are preserved as small dots — the gaps are part of the data, just as they are in chemistry.
Filter by mechanism-family or regulatory-status pills. Selecting multiple pills applies them as an "or" — useful for comparing, say, all FDA-approved and legally-compounded peptides in one view. Hover any cell for a quick visual preview.
ProPeptideGuide is editorial in nature and does not provide medical advice. The map indicates general regulatory status as of the verification dates on each individual page; specific prescribing, compounding, and importation rules can change without notice.

Mechanism family
Regulatory status
Liraglutide
LirGLP-1 receptor agonist; FDA-approved for type 2 diabetes (Victoza) and chronic weight management in adults and adolescents 12+ (Saxenda).
Tesamorelin
TesGHRF analogue; the only FDA-approved medication for reduction of excess abdominal fat in HIV-infected adults with lipodystrophy (Egrifta SV, Egrifta WR).
PT-141
PT1Bremelanotide; FDA-approved as Vyleesi for hypoactive sexual desire disorder in premenopausal women.
Sermorelin
SerGHRH(1-29) analogue; previously FDA-approved as Geref for pediatric GHD. Currently accessed primarily through prescription compounding pathways.
Glutathione
GSHEndogenous tripeptide antioxidant (γ-Glu-Cys-Gly). Listed in FDA 503A and 503B Category 1 interim bulk-substance lists; injectable compounding requires strict sterile controls per 2019 FDA alert.
NAD+ IV
NADNAD+ administered intravenously through compounding clinics. Regulatory status varies by state; FDA has issued warning letters to specific marketers.
MK-677
MK6Ibutamoren — small-molecule, oral GHS-R agonist (not strictly a peptide). Not FDA-approved; not legal as a dietary supplement.
LL-37
LL3Cathelicidin antimicrobial peptide. Studied in wound healing and antimicrobial contexts; no approved U.S. pathway.
Thymulin
ThmZinc-bound thymic peptide; research-only in the U.S. with no compliant compounding pathway.
Epitalon
EpiSynthetic tetrapeptide popularized in longevity contexts. No FDA-approved or compliant U.S. compounding pathway.
DSIP
DSIDelta sleep-inducing peptide; research-only with no FDA-approved or compliant U.S. compounding pathway.
Melanotan II
MT2Synthetic melanocortin agonist marketed for tanning. Not FDA-approved; FDA has warned consumers against use.
NR
NRNicotinamide riboside. NAD+ precursor sold as a dietary supplement. Not a peptide; included for wellness-context completeness.
Cagrilintide
CagInvestigational long-acting amylin analogue; studied alone and combined with semaglutide (CagriSema) for chronic weight management.
SS-31
SS3Elamipretide. Mitochondria-targeting peptide investigated in primary mitochondrial myopathy and Barth syndrome.
Kisspeptin
KisHypothalamic neuropeptide regulating GnRH and reproductive hormones. Investigational for hypogonadism and related conditions.
Argireline
ArgAcetyl hexapeptide-8. Cosmetic ingredient marketed as a topical alternative to neurotoxin-based wrinkle treatment.
Color = mechanism family
Each column corresponds to a mechanism family, rendered as a saturated background fill on its cells. The horizontal axis runs from metabolic on the left to neurological and cosmetic on the right.
Row = regulatory status
Rows run top-to-bottom from most-legal to least: FDA-approved, legally compounded, compounded with regulatory complexity, not currently legal in the US, investigational, and cosmetic-only. The vertical gradient bar reinforces the ordering.
Symbol = peptide identifier
Each cell shows a short two-or-three-character symbol derived from the peptide name — Sem, Tir, Lir, BPC, GHK, hCG, NAD, and so on. The symbol is the dominant visual element of the cell, the way "He" or "Au" reads on the periodic table.
