Understanding Research Peptides
Peptides are short chains of amino acids that act as biological messengers, regulating virtually every physiological process. Our catalog covers key research areas including metabolic function, tissue repair, growth hormone axis, and neuroprotection.
BPC-157
A 15-amino acid peptide derived from human gastric juice. Widely studied for its remarkable regenerative properties in tendon, ligament, muscle, and gut tissue repair research.
TB-500
A synthetic version of the naturally occurring Thymosin Beta-4 protein. Studied for wound healing, actin polymerization, and its role in cardiac and skeletal muscle repair models.
GHK-Cu
A naturally occurring tripeptide-copper complex found in human plasma. Research focuses on its roles in skin remodeling, collagen synthesis, anti-inflammatory signaling, and DNA repair.
CJC-1295
A synthetic analogue of growth hormone-releasing hormone (GHRH) with an extended half-life. Used in research studying pulsatile GH secretion, IGF-1 levels, and somatotroph axis function.
Ipamorelin
A highly selective growth hormone releasing peptide (GHRP) with a clean stimulation profile. Studied for its selective GH release without significant cortisol or prolactin side effects in research models.
Semax
A synthetic heptapeptide derived from ACTH(4-7). Research focuses on neuroprotection, BDNF upregulation, serotonin, dopamine, and noradrenaline modulation in preclinical models.
Synthesis
Peptides are synthesized using solid-phase peptide synthesis (SPPS) under strict GMP-compliant conditions.
Purification
Reverse-phase HPLC purification removes impurities, achieving >99% purity standards consistently.
