However, any consideration of these peptides must come with medical oversight, safe sourcing, and clear understanding that they are still research products
It is not even the peptide itself
Product sourcing for controlled experiments: Thymosin Beta-4 (TB-500) 5 mg
This requirement remains the same during pregnancy and breastfeeding
What a COA (Certificate of Analysis) Should Include Identity Confirmation Mass spectrometry confirming molecular weight ~419.4 Da (molecular formula C22H21N5O3) NMR or LC-MS/MS structural confirmation for a small molecule (peptide vendors often skip this small-molecule identity confirmation is non-negotiable here) Purity Testing HPLC purity 98%+ minimum Single dominant peak on the HPLC chromatogram Contamination Testing Residual solvent panel (DMSO, ethanol, acetone all common in small-molecule synthesis) Heavy metals screen Endotoxin testing if the product is positioned for injectable use How to Verify a COA Is Legitimate Match lot number to batch
