Sterility vs Purity vs Endotoxin: Different Quality Questions
Sterility, purity and endotoxin status answer different quality questions and should not be collapsed into one vague testing claim.
99% purity
What Does 99% Peptide Purity Mean?
A 99% peptide purity statement usually refers to chromatographic area percent under a defined method, not a universal guarantee of every quality attribute.
Labeling

CJC-1295 no DAC Research Overview: GHRH Analog Context and Naming
CJC-1295 no DAC is discussed as a modified GHRH analog where exact naming matters because DAC and no-DAC versions are not the same material.
Semax
Semax Research Overview: ACTH Fragment Analog and Peptide Stability Context
Semax is commonly discussed as an ACTH-fragment-related synthetic heptapeptide in neurochemical, peptidase-stability and regulatory-peptide research.
Selank

Tesamorelin
Tesamorelin Research Overview: GHRH Analog, Product Status and Documentation
Tesamorelin is a synthetic GHRH analog name that also appears in regulated pharmaceutical contexts, so research-use product status must be kept separate.
Lyophilization
Lyophilized Peptides: Why Research Peptides Are Supplied as Dry Powder
Lyophilized peptides are dry, freeze-dried research materials. The dry format helps separate peptide identity, storage stability and later laboratory preparation.
