# Should I get my peptides independently tested?

That is your choice. Sable's specification is at least 99% HPLC purity with mass-spectrometry identity, and the lot certificate is emailed within 2 hours. If you test independently, ask for purity plus identity, because HPLC purity alone cannot tell which compound a peak is.
