Trusted US Supplier of Lab-Tested Research Peptides

Hi-Tech Peptides provides lab-tested, high-purity research peptides in the USA, with third-party COAs available on every product.

Quality is at the center of everything we do.

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.
