Retatrutide
Next-generation single-peptide triple agonist targeting GLP-1, GIP, and Glucagon receptors, demonstrating unmatched body weight reduction and hepatic fat clearance in Phase 2 clinical trials.
Tirzepatide
Dual GIP and GLP-1 receptor agonist engineered with a 39-amino acid modified sequence and C20 fatty diacid moiety that delivers profound metabolic control and fat loss.
Semaglutide
Long-acting GLP-1 receptor agonist with 94% homology to human GLP-1, featuring albumin-binding fatty acid chain for once-weekly metabolic enhancement and appetite suppression.
Cagrilintide
Long-acting synthetic amylin analogue acylated for once-weekly subcutaneous dosing; works via distinct non-GLP neural pathways to trigger powerful early satiety and delayed gastric emptying.
AOD-9604
Modified C-terminal fragment of human Growth Hormone (hGH 177-191) with an added tyrosine, specifically stimulating lipolysis and inhibiting lipogenesis without affecting IGF-1 or blood glucose.
MOTS-c
Mitochondrial-derived peptide encoded in the 12S rRNA that regulates metabolic homeostasis, activates AMPK, reverses insulin resistance, and acts as a profound exercise-mimetic.
5-Amino-1MQ
Small molecule / peptide-adjacent oral compound that selectively inhibits Nicotinamide N-methyltransferase (NNMT), revitalizing cellular metabolism and accelerating adipocyte shrinkage.
BPC-157
Synthetic 15-amino acid peptide derived from human gastric juice protein, celebrated for systemic angiogenic, tendon, ligament, gut mucosa, and neuroprotective regenerative properties.
TB-500 (Thymosin Beta-4)
Synthetic fraction of the naturally occurring 43-amino acid protein Thymosin Beta-4 that sequesters actin, promotes cell migration, reduces fibrosis, and accelerates systemic tissue healing.
GHK-Cu (Copper Peptide)
Naturally occurring human tripeptide with high affinity for copper(II) ions, renowned for resetting gene expression to a younger state, boosting collagen/elastin synthesis, and reversing fibrosis.
ARA-290 (Cibinetide)
11-amino acid peptide derived from erythropoietin (EPO) that selectively activates the Innate Repair Receptor (IRR) without stimulating erythropoiesis, reversing small fiber neuropathy and neuropathic pain.
KPV
Naturally occurring C-terminal tripeptide fragment of alpha-Melanocyte-Stimulating Hormone (alpha-MSH) with potent anti-inflammatory, antimicrobial, and gut barrier restorative actions without pigment changes.
CJC-1295 (No DAC) / Mod GRF 1-29
Tetrasubstituted 29-amino acid GHRH analog engineered for enhanced metabolic stability, inducing natural pulsatile Growth Hormone and IGF-1 secretion without desensitizing receptors.
Ipamorelin
Third-generation selective ghrelin receptor (GHSR-1a) agonist pentapeptide that stimulates pure Growth Hormone release without raising prolactin, cortisol, aldosterone, or appetite.
Tesamorelin
Stabilized synthetic GHRH analog with a trans-3-hexenoyl group that potently reduces visceral adipose tissue (VAT) and improves lipid and cognitive profiles.
Sermorelin
Bioidentical 29-amino acid functional fragment of human Growth Hormone-Releasing Hormone, restoring natural pituitary pulsatility and vitality with an outstanding clinical safety history.
IGF-1 LR3
Recombinant 83-amino acid analog of human IGF-1 modified with an Arg substitution and 13-amino acid N-terminal extension that drastically lowers binding to inhibitory IGFBPs, resulting in extraordinary potency.
Epithalon (Epitalon)
Synthetic tetrapeptide based on pineal gland extract that activates telomerase, elongates telomeres, normalizes circadian rhythms, and extends healthy biological lifespan in mammalian studies.
SS-31 (Elamipretide)
Mitochondria-targeting tetrapeptide that selectively binds cardiolipin in the inner mitochondrial membrane, restoring electron transport efficiency, reducing ROS, and rejuvenating aged bioenergetics.
FOXO4-DRI
D-retro-inverso peptide that disrupts the FOXO4-p53 interaction specifically in senescent "zombie" cells, triggering targeted apoptosis of senescent cells while leaving healthy cells completely unharmed.
