Products & Quality

Peptides are short chains of amino acids - the building blocks of proteins. Research peptides are synthetic versions of naturally occurring peptides, manufactured under controlled conditions for use in scientific research. They are sold strictly for in-vitro and laboratory research purposes.

All products are manufactured to 99%+ purity as confirmed by HPLC (High Performance Liquid Chromatography) analysis. Mass spectrometry (MS) is also used to verify molecular identity. Every batch is tested before dispatch.

GMP stands for Good Manufacturing Practice - a globally recognised quality framework enforced in pharmaceutical and research compound manufacturing. GMP certification means the production facility meets strict standards for cleanliness, documentation, equipment calibration, and quality control.

A COA is an official document from an independent third-party laboratory confirming the identity, purity, and potency of a batch of compound. Our COA documents are available on our Quality Standards page.

Yes. Every product batch is sent to an independent, accredited laboratory for analysis before we dispatch orders. We do not rely solely on manufacturer certificates - we verify independently.

Lyophilised (freeze-dried) peptides should be stored at −20°C for long-term storage (up to 24 months) or at 4°C for short-term use (up to 4 weeks). Once reconstituted:

• Store at 4°C and use within 2–4 weeks
• Avoid repeated freeze-thaw cycles
• Protect from direct light
• Use bacteriostatic water for reconstitution when storing reconstituted peptides

Most peptides are supplied as lyophilised (freeze-dried) white powder in sealed vials, with the quantity and lot number printed on the label. Some products are supplied as pre-made solutions where noted on the product page.

No. All products sold by BuyPeptides.now are strictly for in-vitro research and laboratory use only. They are not intended for human or veterinary use, diagnosis, treatment, or prevention of any disease. By purchasing, you confirm you are a qualified researcher using the compounds within applicable laws.

Lyophilised peptides stored at −20°C have a shelf life of 24 months from the date of manufacture. Batch dates are indicated on the vial label. We do not ship products with less than 12 months remaining shelf life.

Yes. If you need the COA for a specific batch lot included in your shipment, include this in an order note or support ticket with your order number and we will send it directly.
