Semaglutide is a GLP-1 receptor agonist that mimics native GLP-1 to stimulate insulin secretion in a glucose-dependent manner while suppressing glucagon release. The Aib substitution at position 2 confers resistance to DPP-IV enzymatic degradation, and the C18 fatty diacid chain enables high-affinity albumin binding, extending its half-life substantially. It also acts on hypothalamic appetite centers to reduce food intake and delay gastric emptying.

Tirzepatide is a dual GIP and GLP-1 receptor agonist that activates both incretin pathways simultaneously. It stimulates insulin secretion, suppresses glucagon in a glucose-dependent manner, and reduces appetite via central and peripheral signaling. The dual receptor engagement provides synergistic metabolic effects beyond GLP-1 agonism alone, including enhanced lipid metabolism and improved insulin sensitivity.

Retatrutide is a triple hormone receptor agonist that simultaneously activates GLP-1, GIP, and glucagon (GCGR) receptors. GLP-1 and GIP agonism drive insulin secretion and appetite suppression, while glucagon receptor activation increases energy expenditure and hepatic lipid oxidation. This triple mechanism addresses multiple metabolic pathways for potentially superior metabolic research and metabolic improvement over dual agonists.

BPC-157 is a synthetic 15-amino acid fragment derived from human gastric body protection compound. It promotes angiogenesis by upregulating VEGF and its receptor VEGFR2, activates the FAK-paxillin pathway to enhance cell migration and wound closure, and modulates the nitric oxide system. It also interacts with the dopaminergic system and has cytoprotective effects on gastrointestinal mucosa, tendons, ligaments, and other connective tissues.

TB-500 (synthetic thymosin beta-4) is studied for its role in actin dynamics, a core process that helps cells migrate, reorganize, and respond to repair signals. Published literature has examined its interaction with angiogenic signaling, inflammatory pathways, and tissue-remodeling biology across multiple preclinical models. The active region LKKTETQ is considered central to its actin-binding activity.

Mod GRF 1-29 is a modified 29-amino acid fragment of GHRH with four amino acid substitutions that prevent enzymatic degradation: D-Ala2 prevents DPP-IV cleavage, Gln8 prevents asparagine rearrangement, Ala15 enhances bioactivity, and Leu27 prevents methionine oxidation. Without the DAC moiety, it produces more physiologic pulsatile GH release patterns, stimulating somatotrophs through GHRH receptors with a much shorter duration of action.

Ipamorelin is a highly selective growth hormone secretagogue that acts on the ghrelin/GHS receptor (GHSR) in the pituitary to stimulate pulsatile GH release. Unlike other GHRPs, ipamorelin does not significantly affect cortisol, ACTH, or prolactin levels at GH-releasing doses, making it the most selective GHS available. It works synergistically with GHRH analogs (like CJC-1295) to amplify GH pulses while maintaining the natural pulsatile release pattern.

MK-677 is an orally active, non-peptidic ghrelin receptor (GHSR-1a) agonist that mimics the GH-releasing activity of ghrelin. It stimulates pituitary GH release by binding to GHSR-1a, increasing GH pulse amplitude without altering pulse frequency. It also increases IGF-1 levels, promotes nitrogen retention, and stimulates appetite. Unlike peptide GH secretagogues, it is orally bioavailable and has a long duration of action, maintaining elevated GH and IGF-1 levels with once-daily dosing.

Epithalon is a synthetic tetrapeptide based on the natural epithalamin produced by the pineal gland. It activates telomerase (hTERT), the enzyme responsible for adding telomeric repeats to chromosome ends, thereby extending telomere length and increasing cellular replicative capacity. It also stimulates melatonin production from the pineal gland, restoring circadian rhythm function that declines with age. Additionally, it modulates antioxidant enzyme expression and has been shown to extend lifespan in animal models.

NAD+ is an essential coenzyme present in all living cells that serves as an electron carrier in metabolic redox reactions (glycolysis, TCA cycle, oxidative phosphorylation) and as a substrate for NAD+-consuming enzymes including sirtuins (SIRT1-7), PARPs, and CD38. Sirtuins are NAD+-dependent deacetylases that regulate DNA repair, mitochondrial biogenesis, inflammation, and stress resistance. NAD+ levels decline with age, and restoring NAD+ activates these protective pathways, enhancing cellular energy production, DNA repair capacity, and stress resilience.

Semax is a synthetic heptapeptide analog of ACTH(4-10) with a stabilizing Pro-Gly-Pro extension. It increases BDNF and TrkB receptor expression, enhances neurotrophic factor signaling, modulates dopaminergic and serotonergic neurotransmission, and provides neuroprotection through antioxidant and inflammatory-pathway mechanisms. Unlike ACTH, Semax has no steroidogenic activity. It improves cerebral circulation, enhances memory consolidation, and has been approved in Russia and Ukraine for stroke recovery and cognitive enhancement.

Thymosin Alpha 1 is a naturally occurring thymic peptide that acts as an immunomodulator by enhancing T-cell maturation, differentiation, and function. It stimulates the production of Th1 cytokines (IL-2, IFN-gamma) while suppressing Th2 responses, activates dendritic cells and natural killer cells, and enhances antibody responses to vaccines. It signals through TLR2, TLR9, and TLR3 on dendritic cells and modulates the mTOR pathway for immune cell differentiation.

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It functions as a signaling molecule that resets gene expression to a healthier state, upregulating genes involved in antioxidant defense, DNA repair, and tissue remodeling while downregulating inflammatory and tissue-destructive genes. It stimulates collagen synthesis, glycosaminoglycan production, and angiogenesis. The copper ion is essential for activating copper-dependent enzymes like lysyl oxidase (collagen cross-linking) and superoxide dismutase.

AOD9604 is a modified 16-amino acid fragment of human growth hormone spanning residues 176-191 with a tyrosine substitution. It stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat formation) without affecting blood glucose levels or growth parameters. Unlike full HGH, it does not compete for the GH receptor and does not induce IGF-1 elevation or insulin resistance, specifically targeting fat metabolism pathways.

Humanin is a mitochondrial-derived peptide encoded by the MT-RNR2 gene (16S ribosomal RNA). It exerts cytoprotective effects by binding to IGFBP-3 (blocking its pro-apoptotic effects), binding to BAX (preventing mitochondrial membrane permeabilization and apoptosis), and activating the STAT3 signaling pathway via the CNTFR/WSX-1/gp130 receptor complex. Humanin protects neurons from amyloid-beta toxicity and has broad anti-apoptotic, inflammatory-pathway, and metabolic regulatory functions.
