A COA for every batch, published against the batch number
Each release is verified by reversed-phase HPLC and mass spectrometry at an independent lab, and the certificate of analysis is registered to the exact batch number printed on your vial.

The Molequa alternative for lab-verified research peptides
Molequa runs text advertising in Slovak search built almost entirely on two promises: 99% purity and a 25% signup discount. It is a discount-led acquisition model, and the headline purity figure does most of the persuasive work.
Updated
A stated purity number and a verifiable one are different things, and that difference is the whole comparison here. The useful question is not whether a supplier claims 99% — most do — but whether you can open the certificate that proves it for the vial in your hand.

Questions about switching
- Molequa advertises 99% purity — how is Ascend Labs different?
- The claim is similar; the evidence is the difference. Ascend Labs releases batches at ≥99% HPLC purity and publishes the certificate of analysis against the batch number printed on the vial, so you can read the actual chromatography result for your batch. When comparing any supplier, ask whether the purity figure is backed by a document tied to your specific batch or stated only in advertising.
- Is a signup discount a good way to choose a peptide supplier?
- It is a reasonable tiebreaker, but not a first filter. A discount changes what you pay once; batch documentation changes whether the material is usable for research at all. Compare the certificate availability first, then the price.
- Is Ascend Labs a good Molequa alternative?
- Ascend Labs is a European research-peptide supplier focused on verifiable quality: every batch is HPLC- and MS-tested at ≥99% purity with a certificate of analysis published against the batch number. If purity documentation and fast EU shipping are your priorities, it's a strong alternative.
- Can I verify purity before I order?
- Yes. Certificates of analysis are published against each batch number, so you can review the HPLC result before ordering.
- Are these products for human use?
- No. All products are sold strictly for laboratory research purposes only — not for human or veterinary consumption.
