Ipamorelin 5mg

Ipamorelin represents a synthetic pentapeptide derived from GHRP-1, which has a very potent growth hormone (GH) releasing properties with efficacy and potency comparable to GHRP-6, both in vitro and in vivo. Unlike other GH secretagogues, ipamorelin very surprisingly does not induce a significant increase in adrenocorticotropic hormone (ACTH) or cortisol...

CJC-1295 no DAC (Mod GRF 1-29) 5mg

CJC-1295 no DAC (Mod GRF 1-29) is a synthetic peptide identical to CJC-1295 without DAC compound. It is truncated analogue of growth hormone releasing hormone (GHRH), which was developed in 1980s from original GRF 1-29, but with purposefully prolonged half-life to ensure better therapeutical use. This modified version was shown to have similar or even the...

AOD-9604 5mg

AOD-9604, lipolytic peptide fragment, which was derived from human growth hormone (HGH) during the late 1990s was modified from HGH residues 176-191. This modified compound primarily works as an element for fat burning and obesity treatment, while the exact mechanism by which this happens is still under research. It stimulates the breakdown (metabolism)...

Endotoxin Testing: Why It Matters in Peptide Quality Assessment

Endotoxin testing is a key part of peptide quality assessment because endotoxins cannot be detected through HPLC purity, identity, or peptide content testing alone. Dedicated testing provides independent information about microbiological quality, manufacturing controls, and batch-specific safety parameters.

Peptide Certificate of Analysis: How to Verify a COA and Identify Authentic Laboratory Reports

A Peptide Certificate of Analysis (COA) summarizes laboratory results for a specific batch. A reliable COA should clearly identify the sample, batch, testing laboratory, analytical methods and results, while allowing independent verification where possible. Batch-specific traceability and comprehensive testing make the document far more valuable than a purity result alone.

HPLC Purity: Why It Is Not Enough to Define Peptide Quality

HPLC purity is an important indicator of peptide quality, but it does not provide a complete picture. A comprehensive assessment also includes identity, peptide content, endotoxins, heavy metals, microbiological testing, batch consistency and traceable documentation.
