BPC-157 (Body Protection Compound-157)
BPC-157 is a synthetic pentadecapeptide consisting of 15 amino acids, derived from a protective protein naturally found in human gastric juice. It is one of the most widely studied peptides in preclinical research, with over 100 peer-reviewed publications examining its cytoprotective, anti-inflammatory, and tissue-repair properties. Research focuses on its potential for accelerated healing, gastrointestinal protection, and neuroprotection.
TB-500 (Thymosin Beta-4)
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring 43-amino-acid peptide involved in cell migration, differentiation, and tissue repair. It works by sequestering G-actin to promote cell motility and has been studied for its role in wound healing, cardiac repair, and reducing inflammation. Research indicates it may complement BPC-157 through different repair mechanisms.
CJC-1295
CJC-1295 is a synthetic analog of Growth Hormone Releasing Hormone (GHRH). Modified with Drug Affinity Complex (DAC) for extended half-life, it stimulates the pituitary gland to increase natural growth hormone and IGF-1 levels. Commonly studied in combination with Ipamorelin for synergistic effects on body composition, recovery, and anti-aging research.
Ipamorelin
Ipamorelin is a selective growth hormone secretagogue that activates ghrelin receptors (GHS-R1a) to stimulate pulsatile GH release. Unlike older secretagogues, it does not significantly elevate cortisol, prolactin, or ACTH, making it one of the cleanest GH-releasing peptides studied. Often paired with CJC-1295 for enhanced growth hormone research.
GHK-Cu (Copper Peptide)
GHK-Cu is a naturally occurring copper-binding tripeptide (Glycyl-L-Histidyl-L-Lysine) first identified in human plasma. It plays a critical role in wound healing, tissue remodeling, and skin regeneration. Research has demonstrated its ability to stimulate collagen synthesis, promote angiogenesis, and reduce oxidative damage. Widely studied in dermatology and aesthetic medicine.
Semaglutide
Semaglutide is a long-acting GLP-1 receptor agonist originally developed for type 2 diabetes management. It mimics the action of human GLP-1 to regulate blood sugar, insulin secretion, and appetite. Clinical research (STEP trials) has demonstrated significant weight management effects, making it one of the most studied peptides for metabolic research.
Melanotan II
Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone (Ξ±-MSH). It binds to melanocortin receptors, primarily MC1R and MC4R, influencing skin pigmentation, appetite regulation, and libido. Studied for its tanning effects and potential photoprotective properties by stimulating melanin production without UV exposure.
NAD+ / NMN
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme essential for cellular energy production, DNA repair, and sirtuin activation. NMN (Nicotinamide Mononucleotide) is its direct precursor. Injectable forms aim to rapidly restore NAD levels, enhance mitochondrial function, and support healthy aging. Central to longevity and anti-aging research.
