Research peptides · Third-party tested · Batch-traceable
Every batch tested. Every certificate published. Buy the lot you can verify.
Most peptide suppliers ask you to trust them. We would rather you checked. Every lot we sell is tested by an independent laboratory, and the certificate for the exact batch in your vial is on the product page, before you pay, not after.
Independent third-party testing · ≥99% purity by HPLC-MS · Endotoxin & sterility screened · Batch-traceable COA on every lot
Featured peptides
A few from the catalogue. Every one ships with a batch-traceable certificate.
How it works
1. We test every batch
Not a representative sample. Not a batch from last year. Every lot, sent to an independent laboratory for identity, purity by HPLC-MS, endotoxin and sterility.
2. We publish the certificate
The COA for your specific lot is linked on the product page and searchable in the COA library. Not a generic PDF. The document for the vial you are buying.
3. You verify, then you buy
Read it first. That is the whole point. If a supplier will not show you the certificate before you pay, you already know what that means.
Why Wellstasis
We cite the studies that do not flatter us.
Our best-selling product page links a controlled study that found no significant effect. We left it there on purpose. A supplier who only shows you the good data is telling you something about how they will behave when the data is bad.
Named lab. Not “an independent lab.”
Anyone can say “third-party tested.” We tell you who.
No dosing. No protocols. No promises.
These are research materials and we sell them as research materials. Anyone telling you otherwise is taking a risk with your money and your licence, not theirs.
