PEPTIDES FOR LABORATORY RESEARCH
Look beyond purity.
A purity percentage is only part of the picture. Explore our published independent laboratory reports for a closer look at the peptide samples tested—from identity and purity to additional analyses where available.
Testing varies by product and sample. Reports apply to the samples tested; not every batch is tested.
Available reports may include identity, purity, heavy metals, endotoxin, or sterility testing. The analyses performed vary by sample.
Third-party tested
Identity and purity on every batch, with a rotating secondary panel for heavy metals, endotoxin and sterility.
Janoshik and US labs
Testing runs through Janoshik Analytical plus US-based laboratories, with every certificate published before the batch ships.
Same-day shipping
Orders placed before 2 PM PST leave the same business day. Two-day UPS Air from California.
