Peptide Gurus

Peptide Gurus is a vendor shipping from the USA, offering both retail and bulk sales. The catalogue is narrow, focused on a small selection of peptides, but COA coverage is extensive — self-hosted reports show purity averaging around 99.6%. The site currently lacks pricing transparency, with no listed prices observed. Community discussion is minimal, with too few mentions to draw conclusions about product quality, shipping experience, or customer service.
