Your body already makes it — it just breaks down in minutes, which is why drug versions had to be re-engineered to last longer.GonadorelinCategorySexual HealthBenefitsLH stimulation, FSH stimulation, Reproductive supportThe FDA-approved synthetic form of the body's own master reproductive hormone, used to trigger LH and FSH release and support natural fertility signaling.H
HCGCategorySexual HealthBenefitsNatural testosterone boost, Reproductive support, Hormonal balanceAn FDA-approved hormone that mimics LH directly at the testes or ovaries, commonly used to support fertility and preserve natural testosterone production during hormone therapy.HexarelinCategoryGrowth HormoneBenefitsGrowth hormone stimulation, Cardioprotection, Muscle growthOne of the most potent growth-hormone-releasing peptides studied, with a distinct cardioprotective effect separate from its GH-stimulating activity.HumaninCategoryLongevity & Anti-AgingBenefitsNeuroprotection, Mitochondrial support, Anti-agingA tiny protein your mitochondria make on their own, first discovered for protecting brain cells in Alzheimer's research. Levels drop as you age, making it a longevity-research target.M
MazdutideCategoryWeight Loss & MetabolismBenefitsWeight loss, Increased energy expenditure, Blood sugar regulationA dual GLP-1/glucagon receptor agonist approved in China for weight management, combining appetite suppression with increased energy expenditure.Melanotan ICategoryAesthetic & BeautyBenefitsSkin pigmentation, PhotoprotectionThe tanning peptide that's actually FDA approved — but only as an implant for a rare sun-sensitivity disease, not for cosmetic tanning.Melanotan IICategoryAesthetic & BeautyBenefitsSkin pigmentation, Increased libidoThe unregulated, widely sold 'tanning peptide' — never FDA approved.
