Peptide Library
Searchable, scored, and cited. Every peptide page pulls live data from institutional sources (FDA, NIH, EMBL-EBI). Browse by goal below or filter by evidence quality.
Educational only — not medical advice. SmartPeptide does not prescribe, diagnose, or treat. Always consult a licensed healthcare provider before using any peptide, supplement, medication, or protocol.
Note on this filter: peptides appear here because oncology research is mentioned in their published literature — NOT because they are cancer treatments. No peptide on SmartPeptide is presented as a cancer therapy. Always work with a qualified oncologist.
Sermorelin
LongevityGHRH analog (first 29 amino acids of human GHRH). Stimulates endogenous growth hormone release. Approved for pediatric GH deficiency, widely used off-label in adults.
NAD+ (Nicotinamide Adenine Dinucleotide)
LongevityCoenzyme essential for cellular energy production and DNA repair (NOT a peptide — it's a nucleotide). Available as IV infusion, intranasal, and oral precursors (NR, NMN). Heavily discussed in longevity communities. Direct NAD+ supplementation has weak human RCT support; precursors have somewhat better data.
Kisspeptin
OtherNeuropeptide encoded by the KISS1 gene. Master regulator of the hypothalamic-pituitary-gonadal axis — stimulates GnRH release and downstream LH/FSH/sex-hormone production. Studied as a diagnostic and therapeutic agent for hypogonadism, infertility, and sexual function. Not FDA-approved.
Melanotan II
SkinSynthetic analog of α-melanocyte-stimulating hormone (α-MSH). Binds melanocortin receptors (notably MC1R for tanning and MC4R for sexual function). Originally researched for therapeutic skin pigmentation; abandoned in clinical development. Sold heavily as a grey-market 'tanning peptide.' Significant safety concerns — Class A action by some regulators.
