Q&As

Here are some of our most asked questions!

We do U.S. based lab 3rd party testing of every batch for purity and identification. The Manufacturing COA (Certificate of Analysis) is available upon request for lab research professionals and institutions. 

SemaLabs is committed to offering the most competitive pricing with guarantees of quality and transparency.  We beat all industry pricing without any compromises. We ensure research-grade standards while also offering product credit for your own 3rd party testing.

With certain exceptions E.g. (BAC Water) most peptides should be stored in a cool, dry place like a refrigerator when reconstituted. Freezer storage is recommended for longevity on peptides that are still in freeze dried powder form.

All of our products are strictly intended for research only and are not intended for human or veterinary use. This is in our agreement terms when purchasing.

All of our products are intended for research purposes only and should be handled by qualified individuals in a controlled lab environment. 

When a production batch is not waiting on 3rd party testing, In stock orders are promptly shipped via UPS. Returns/Exchanges are only accepted for incorrect shipments or damaged goods. Due to the tamper proof nature of our research peptides, all sales are final.

Yes we do! We offer credit towards the vial if purchased individually or towards half your 10 pack quantity. JANOSHIK is the only testing platform that we support this on, and you need to properly accredit us as a supplier as well as contact us prior.
