Are NXT GEN peptides pharmaceutical grade?

Yes. Every batch is HPLC and mass-spectrometry tested, with purity independently confirmed at up to 99.9% depending on the compound. A Certificate of Analysis (COA) accompanies every lot.

What shipping do you offer?

Free express, stealth and temperature-controlled shipping is included on orders over £150. All orders are dispatched discreetly.

Are these products for human consumption?

No. All products are supplied strictly for research and laboratory evaluation purposes only. They are not intended for human or animal consumption, or to diagnose, treat, cure or prevent any disease.
