Especificação publicada do fornecedor, lotes selecionados testados de forma independente

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.

Retatrutide Laboratory Reconstitution Bundle
Retatrutide Research Starter Kit — everything needed to begin retatrutide research in one bundle. Includes: retatrutide 10mg (lyophilized, ≥98% purity per supplier batch spec), bacteriostatic water 5ml, 2 × 3ml syringes, 5 × 1ml insulin syringes. Kit saves EUR 27.47 vs buying components separately. Research use only.

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 (≥98% supplier batch specification; selected lots independently tested, 99.4% avg across published reports; 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 laboratory research use only. Not for human consumption.

TB-500
TB-500 is a synthetic peptide corresponding to the 17-amino acid active region (Ac-SDKP sequence) of Thymosin Beta-4, a naturally occurring 43-amino acid protein. While the full-length Thymosin Beta-4 molecule has broad biological activity, TB-500 retains the key actin-binding domain that drives research interest in cell migration and tissue biology. Shipped to a ≥98% supplier batch specification; selected lots independently tested (99.4% avg across published reports). Key research areas: Cell migration and tissue remodeling Actin-binding and cytoskeletal dynamics Cardiac tissue biology and cellular signaling Important distinction: TB-500 is a fragment of Thymosin Beta-4, not a synonym for it. Full-length Thymosin Beta-4 (43 aa) has broader systemic activity, while TB-500 (17 aa) retains the active actin-sequestering region. 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. Shipped to a ≥98% supplier batch specification; selected lots independently tested (99.4% avg across published reports). 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. Shipped to a ≥98% supplier batch specification; selected lots independently tested (99.4% avg across published reports). 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.

CJC-1295 With DAC
Research-grade CJC-1295 With DAC. ≥98% supplier batch specification; selected lots independently tested (99.4% avg across published reports). Lyophilized powder in sealed glass vial.

Ipamorelin
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue that selectively activates the ghrelin/GHS receptor. It is recognized for its high selectivity in stimulating growth hormone release without significantly affecting other pituitary hormones. Selective GH secretagogue (ghrelin receptor agonist) Growth hormone pulsatility research Gastrointestinal motility studies For research purposes only.

BPC-157 + TB-500 Blend
Synergistic blend combining BPC-157 (VEGFR2/NO/FAK pathways) and TB-500 (actin regulation/progenitor cell mobilization) for multi-pathway tissue repair research. ≥98% supplier batch specification per component; selected lots independently tested (99.4% avg across published reports). For laboratory research use only.

Bacteriostatic Water
USP-grade bacteriostatic water (3ml) with 0.9% benzyl alcohol. Sterile, endotoxin-tested. For peptide reconstitution.
3ml3ml Syringes 10-Pack
Pack of 10 sterile disposable 3ml Luer lock syringes with graduated markings. Ideal for drawing bacteriostatic water from vials during reconstitution of lyophilized peptides. For laboratory research use only.

Peptide Mixing Kit
Peptide Mixing Kit — complete reconstitution and storage bundle for research peptides. Kit includes: 3 × 5ml bacteriostatic water, 10 × insulin syringes (29G, 1ml), 5 × alcohol swabs (70% IPA), and 2 × 3ml storage vials. Research use only.
