Are your peptides tested for purity?
Yes. Every batch undergoes advanced 6-panel third-party testing to verify purity, identity, and quality before distribution.
Our testing protocol includes:
- Qualitative Identification (UV-Vis)
- Percent Purity (HPLC)
- Quantitative Assay
- Heavy Metals screening
- Microbial testing (TAMC)
- Yeast & Mold testing (TYMC)
What is a Certificate of Analysis (CoA) and how do i read it?
A Certificate of Analysis is an official lab document that verifies your peptide’s quality. Key sections include: Purity (should be 99%+), Identity (confirms correct peptide via mass spec), Appearance (should match product description), and Endotoxin levels (should be below 1 EU/mg). Each CoA is batch-specific and available on product pages.
How should I store peptides?
Lyophilized (freeze-dried) peptides are very stable. For short-term storage (under 3 months), room temperature in a cool, dark place is fine. For long-term storage, refrigerate at 2–8°C or freeze at -20°C. Avoid repeated freeze-thaw cycles. Properly stored lyophilized peptides can remain stable for 2+ years.
