Visit Vanguard Research Institute →This is the checklist inside the guide. It's how you size up any research‑compound supplier in about a minute — no lab required.
The lab report stating a compound's identity and purity for the exact lot you receive — not a generic "typical" spec. No lot‑specific COA, no deal.
"High purity" is a marketing phrase until it's a figure from a named method. HPLC is the standard — ask for the percentage and the method, per lot.
Purity tells you how much of the sample is the target compound. Identity — often confirmed by mass spectrometry — confirms it's the right compound at all.
The lot number on the COA should match the lot on the vial in your hand. Traceability is how a result can be reproduced later.
Documentation is downstream of good sourcing. Ask where the material originates and whether that facility is cGMP‑certified. Vague answers are an answer.
Peptides are sensitive to heat and moisture. How a supplier ships tells you how seriously they take what's inside — handling is part of the product.
Clear "For Research Use Only" labeling and no human‑use or benefit claims. Honest labeling is a signal of a supplier that respects the category.

All Vanguard material is clearly labeled For Research Use Only — not for human consumption.
