While many companies advertise only “99% HPLC purity,” we go above and beyond by evaluating
additional quality attributes that purity testing alone cannot establish.
Hi-Tech Peptides conducts comprehensive lot-release testing panels that evaluate
identity, purity, peptide content and assay, net content, sterility, endotoxins,
heavy metals, residual solvents, moisture, counter-ions, appearance, and conformity.
The exact testing panel is determined by each product’s intended research specifications
and applicable quality requirements.
A high HPLC purity result is important, but it does not independently confirm
identity, actual peptide content, net quantity, sterility, endotoxin levels,
residual solvents, moisture, heavy-metal content, or overall conformity.
Our broader testing approach is designed to provide a more complete quality profile
for every applicable lot.
