Research Peptides

IGF-1 LR3 (Long Arg3 IGF-1) is an 83-amino acid analog of insulin-like growth factor 1 with an arginine substitution at position 3 and a 13-amino acid N-terminal extension. These modifications significantly reduce IGF binding protein affinity, increasing bioavailability in research applications. Extended analog of IGF-1 with enhanced bioavailability Muscle hypertrophy and tissue growth studies IGF-1 signaling pathway and receptor activation research For research purposes only.

Research-grade GDF-8. 99.3% avg purity, HPLC & MS verified. Lyophilized powder in sealed glass vial. For laboratory research use only. Not for human consumption.

Synergistic blend combining BPC-157 (VEGFR2/NO/FAK pathways) and TB-500 (actin regulation/progenitor cell mobilization) for multi-pathway tissue repair research. 99.3% avg purity per component. For laboratory research use only.

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. Supplied at 99.3% avg purity (HPLC-verified), with Certificate of Analysis for every batch. 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.

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 (99.3% avg HPLC purity, 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.
