Semaglutide
Also known as: Ozempic, Wegovy
A GLP-1 receptor agonist that reduces appetite and slows gastric emptying. One of the most clinically validated weight loss agents available.
Tirzepatide
Also known as: Mounjaro, Zepbound
A dual GIP/GLP-1 receptor agonist with superior weight loss outcomes to semaglutide in head-to-head SURMOUNT trials.
AOD-9604
Also known as: Anti-Obesity Drug fragment
A modified fragment of human growth hormone that stimulates lipolysis and inhibits lipogenesis without affecting blood sugar or IGF-1 levels.
BPC-157
Also known as: Body Protection Compound 157
A 15-amino-acid peptide derived from gastric juice with potent regenerative, anti-inflammatory, and cytoprotective properties across multiple tissue types.
Epithalon
Also known as: Epitalon, Epithalamin
A tetrapeptide that stimulates telomerase activity, potentially lengthening telomeres and slowing cellular senescence. Extensively studied in Russia since the 1980s.
NAD+
Also known as: Nicotinamide Adenine Dinucleotide
A critical coenzyme in cellular energy metabolism, DNA repair, and sirtuin activation. NAD+ levels decline with age — IV or injectable supplementation restores them rapidly.
Ipamorelin / CJC-1295
Also known as: GHRP + GHRH stack
A synergistic peptide stack that stimulates natural growth hormone pulsation. Ipamorelin triggers GH release; CJC-1295 extends the pulse duration for sustained anabolic effects.
Sermorelin
Also known as: GHRH 1-29, Geref
A synthetic analogue of growth hormone-releasing hormone. Stimulates the pituitary to release GH naturally — a gentler, more physiological alternative to exogenous HGH.
TB-500
Also known as: Thymosin Beta-4
A naturally occurring peptide that promotes actin regulation, angiogenesis, and tissue repair. Widely used for injury recovery, tendon healing, and reducing systemic inflammation.
Semax
Also known as: ACTH(4-7)PGP
A nootropic peptide derived from ACTH that enhances BDNF expression, improves focus and memory, and has neuroprotective properties. Widely used in Russia for cognitive enhancement.
PT-141
Also known as: Bremelanotide, Vyleesi
An FDA-approved melanocortin receptor agonist that directly activates the central nervous system pathways for sexual arousal — effective in both men and women.
GHK-Cu
Also known as: Copper Peptide, Copper Tripeptide-1
A naturally occurring copper-binding peptide that stimulates collagen synthesis, promotes skin remodelling, and has potent antioxidant and anti-inflammatory effects.
Thymosin Alpha-1
Also known as: TA-1, Zadaxin
A thymic peptide that modulates T-cell activity, enhances innate immunity, and has been clinically used in immunocompromised patients and those with chronic infections.
