[Live mechanism]
Identical 191-amino acid GH (somatropin) produced in E. coli. Unlike GHRH/GHRP peptides it bypasses the pituitary and delivers exogenous GH directly
[Body map]
GH receptor (systemic)
JAK2/STAT5
Somatropin binds GHR on the cell surface, dimerizes it and activates the JAK2/STAT5 cascade — the principal signaling pathway for hypertrophy and lipolysis

All peptides undergo HPLC analysis with a guaranteed minimum purity of 98%. In practice, most batches reach 99% or higher — the exact value for your specific batch is documented in the Certificate of Analysis (COA) we ship with every order, issued by an independent accredited laboratory. The COA also documents identity and molecular weight. Additional analytical data is available on request.
Store lyophilized peptides at -20C in a dark, dry environment. In this form, stability is maintained for up to 24 months. After reconstitution, the solution remains stable for 2-4 weeks at 2-8C. Avoid repeated freeze-thaw cycles — aliquot as needed.
Yes. Every batch ships with a Certificate of Analysis (COA) from an independent laboratory. The document includes an HPLC chromatogram with purity data and mass spectrometry analysis confirming molecular identity. COA files are available for download on the product page or sent via email with the order.
