How We Test & Grade Peptide
We adhere to clinical testing standards to filter out under-dosed or impure products.
Anonymous Sample Purchases
We secretly order products from vendors directly to prevent cherry-picked samples from being submitted for testing.
HPLC & Mass Spectrometry
Vials are sent to ISO-accredited 3rd party laboratories (e.g. Janoshik, Colmaric) for High-Performance Liquid Chromatography.
Endotoxin & Dose Verification
We verify exact milligram quantity matches the label and check for heavy metals or bacterial endotoxin contaminants.
Shipping & Support Scoring
We evaluate delivery packaging, temperature protection during transit, refund policies, and customer service response rates.

Frequently Asked Questions
Are research peptides legal to buy online?
Yes, research peptides are legal to purchase in many jurisdictions specifically when sold for laboratory in-vitro research and scientific study purposes. They are strictly not intended for human consumption or therapeutic use.
What is an HPLC Certificate of Analysis (COA)?
High-Performance Liquid Chromatography (HPLC) is an analytical chemistry technique used to separate and quantify components in a peptide mixture. A legitimate COA details the purity percentage (ideally >99%) and mass spectrometry verification of the exact chemical structure.
