Class-level specifications where on record, selected lots independently tested

Retatrutide
Retatrutide is a novel triple-agonist peptide targeting GIP, GLP-1, and glucagon receptors simultaneously. This multi-receptor approach has generated significant research interest in metabolic studies. Triple hormone receptor agonism (GIP/GLP-1/Glucagon) Metabolic pathway modulation research Energy homeostasis and body composition studies For research purposes only.
5mg−32%BPC-157
BPC-157 (Body Protection Compound 157) is a stable 15-amino-acid pentadecapeptide fragment derived from a gastric juice protein, supplied by CertaPeptides as a lyophilized laboratory research compound (class-level specification ≥98%; CAS 137525-51-0). In preclinical literature, Sikiric et al. (2014, PMID 23755725) reported effects on the nitric oxide system in rodent models, and Chang et al. (2014, PMID 25415472) observed increased growth hormone receptor expression in cultured tendon fibroblasts. These findings are reported here for research context only and are not medical claims. For research purposes only. Not for human consumption.

GHK-Cu
GHK-Cu is a naturally occurring copper-binding tripeptide (Glycyl-L-histidyl-L-lysine copper complex) studied extensively in tissue biology and cellular remodeling research. Concentration declines with age, making it a key compound in age-related biological studies. Class-level specification ≥98%; selected lots independently tested. Key research areas: Tissue remodeling and extracellular matrix pathways Collagen and decorin synthesis stimulation Gene expression modulation (over 4,000 genes identified) For research purposes only. Not for human consumption.

Epitalon
Epitalon is a 4-amino acid synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied for telomerase activation and telomere biology research. Derived from pineal gland epithalamin. Class-level specification ≥98%; selected lots independently tested. Key research areas: Telomerase reactivation and telomere elongation in somatic cells Pineal gland neuroendocrine function and melatonin regulation Cellular aging and geroprotective mechanisms For research purposes only. Not for human consumption.

Selank
Selank is a synthetic heptapeptide derived from the endogenous immunomodulatory peptide tuftsin. It has been extensively studied for its anxiolytic-like properties and effects on neuropeptide expression in research models. Tuftsin-derived anxiolytic peptide analog Enkephalin metabolism and neuropeptide studies Immune modulation and CNS receptor binding markers research For research purposes only.

Semax
Semax is a synthetic heptapeptide analog of the adrenocorticotropic hormone fragment ACTH(4-7). It has been studied extensively for its neurotrophic and nootropic properties in various experimental models. ACTH(4-7) analog with enhanced metabolic stability Neurotrophic factor expression and BDNF pathway research CNS receptor binding markers and memory research models For research purposes only. Not for human consumption.

Bacteriostatic Water
USP-grade bacteriostatic water (3ml, 5ml or 10ml vials) with 0.9% benzyl alcohol. Sterile, endotoxin-tested. For peptide reconstitution.

MOTS-c
Research-grade MOTS-c. Class-level specification ≥98%; selected lots independently tested. Lyophilized powder in sealed glass vial. For research purposes only. Not for human consumption.
