Featured Peptides

BPC-157
Best Seller≥99.12%
Regenerative

BPC-157

Body Protection Compound-157 (BPC-157) is a pentadecapeptide consisting of 15 amino acids. It is a partial sequence of body protection compound (BPC) that is discovered in and isolated from human gastric juice. Research has demonstrated its cytoprotective and regenerative properties in various tissue types.

TB-500
≥98.87%
Regenerative

TB-500

Thymosin Beta-4 fragment (TB-500) is a synthetic peptide corresponding to the active region of the naturally occurring thymosin beta-4 protein. It is a 43-amino-acid peptide that has been researched for cell migration, blood vessel formation, and cellular differentiation processes.

Semaglutide
High Demand≥99.45%
GLP-1 Receptor

Semaglutide

Semaglutide is a modified GLP-1 receptor agonist peptide featuring a C-18 fatty acid chain that extends its half-life through albumin binding. It is one of the most widely studied peptides in metabolic research and glucose homeostasis.

GHK-Cu
≥99.03%
Regenerative

GHK-Cu

GHK-Cu (copper peptide) is a naturally occurring tripeptide-copper complex found in human plasma, saliva, and urine. Concentrations decline significantly with age. It has been researched extensively for its role in tissue remodeling, gene expression modulation, and antioxidant signaling.

$34.00/ 10mg
Ipamorelin
≥98.95%
Growth Hormone

Ipamorelin

Ipamorelin is a pentapeptide and selective growth hormone secretagogue (GHS) that acts on the ghrelin receptor. It is considered one of the most selective GH-releasing peptides, stimulating GH release without significantly affecting cortisol, prolactin, or ACTH levels.

$45.00/ 5mg
CJC-1295
≥99.21%
Growth Hormone

CJC-1295

CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH) with Drug Affinity Complex (DAC) technology. The DAC modification extends the peptide half-life by binding to serum albumin, allowing sustained GHRH receptor activation.
