Why COA is Important
COA stands for Certificate of Analysis. Without it, you have no way of knowing what you're actually injecting.
The Single Most Important Safety Check
Vietnam has limited pharmaceutical regulation. Without third-party COA verification, you cannot confirm purity, concentration, or even that the compound is what it claims to be. This is your primary protection against underdosed or fake products.
What a COA Should Include
- Peptide identity confirmed (mass spec or HPLC)
- Purity percentage listed (98%+ for injectables)
- Batch/lot number matching your vial
- Testing date within the last 12 months
- Verifiable third-party lab name
- Testing method clearly stated
Red Flags
- No COA provided at all
- Generic COA without a batch number
- In-house testing only (no third-party verification)
- Old testing dates (over 12 months)
- Unverifiable or made-up lab name
- Purity listed below 98%
- COA that "applies to all products" (not batch-specific)
How to Verify a COA
Request COA Before Purchasing
Any reputable supplier will provide a COA on request. If they hesitate or refuse, walk away.
Match Batch Number
The batch/lot number on the COA must match the batch/lot number on your physical vial.
Research the Testing Lab
Google the lab name. Legitimate labs like Janoshik have a web presence, client reviews, and contact info.
Contact the Lab (If Suspicious)
For expensive orders or suspicious COAs, you can email the lab with the report number to verify it was issued.
Trusted Independent Testing Labs
If you want to independently verify a product you've already purchased, these labs accept samples directly from consumers.

Why This Matters Especially in Vietnam
Vietnam's pharmaceutical regulatory environment is developing. Unlike the US, EU, or Australia, there is no established enforcement mechanism for research peptide quality. This means the market contains both excellent quality products and counterfeit/underdosed compounds.
COA is your primary protection. It's not foolproof — a COA can be fabricated — which is why we recommend only suppliers using verifiable third-party labs like Janoshik, where you can cross-reference the report.
