What to Look for When Buying Sermorelin

The research peptide market is largely unregulated. Quality varies significantly between vendors. Here are the non-negotiable criteria for sourcing research-grade Sermorelin:

Third-party COA from an accredited US lab (HPLC + mass spectrometry)
Purity 98% or higher confirmed by HPLC analysis
Correct molecular weight verified by mass spectrometry
Lyophilized powder in sealed, labeled vials
US-based manufacturer with verifiable address
Transparent return and quality guarantee policy

COA Note: Sermorelin is a 29-amino acid peptide (MW approximately 3,358 Da). Verify HPLC purity and mass spec confirmation of the correct molecular weight.

Red Flags to Avoid

No certificate of analysis, or COA from an unaccredited lab
Price significantly below market rate (often indicates underdosing)
Vague sourcing with no lab details or country of origin
No customer service contact or physical address
Claims of FDA approval or human-use authorization
Suspiciously high purity claims without documentation
