Do Peptides Need to Be Refrigerated? Cold Chain and Transit Stability for Lyophilized Peptides
Whether sealed, lyophilized peptides need cold shipping, how heat exposure adds up in transit (Arrhenius and mean kinetic temperature), what counts as a temperature excursion, and what to check on arrival.
Guide
Endotoxin and Sterility Testing Explained: LAL, rFC and USP 71 Results on a COA
What endotoxin (LAL and recombinant Factor C) and sterility (USP 71) tests measure, how each method works, and how to read EU/mg values and pass/fail results on a Certificate of Analysis.

How to Read a Peptide COA: HPLC Purity and Mass Spec Identity
A plain-language walkthrough of chromatography basics for evaluating peptide Certificates of Analysis.
Guide
Net Peptide Content and Salt Forms: TFA vs Acetate, and Why 10 mg Isn’t 10 mg of Peptide
Why a lyophilized peptide is a salt, how TFA, acetate and chloride counter-ions change the peptide fraction of the powder, how net peptide content is measured, and how it differs from HPLC purity.
Guide
Peptide Storage and Stability: How to Store Lyophilized Peptides
How to store sealed, lyophilized peptides (temperature, moisture, light and temperature cycling) and the degradation chemistry those conditions slow: oxidation, deamidation, hydrolysis and aggregation.
