The Peptide Reference Manual
Every method, handling and verification reference we use, compiled into one document. Free to read.
Research
How to Read a Peptide COA
What each field on the certificate actually reports, which ones carry weight, and how a technically accurate document can still mislead.
Research
HPLC vs Mass Spectrometry
Two techniques answering two different questions. What each one proves, and the specific failure modes each is blind to.
Research
Endotoxin Testing
Endotoxin survives the processes that remove the bacteria producing it, and no purity method will ever see it.
Research
Lyophilized vs Reconstituted
Why the same peptide is stable for years dry and degrades in weeks in solution. The difference is water, and what water permits.
Research
Reading a Chromatogram
The trace carries information the summary percentage discards — peak shape, resolution, and where the baseline was drawn.
Research
Cold Chain in Transit
Cumulative thermal exposure, not peak temperature, is what matters. Where excursions actually happen, and when cold shipping is warranted.
Research
Reconstitution
Concentration arithmetic, choosing a solvent, and the handling errors that lose material without leaving a trace.
Research
Freeze-Thaw and Aliquoting
What happens to a peptide during freezing, why cycles compound, and the one practice that removes the variable entirely.
