Nexxgen research laboratory

Our story

Verified science, every lot

Nexxgen Peptides synthesises research-grade peptides in Australia to a single uncompromising standard: clinical purity, full transparency, and a verifiable Certificate of Analysis behind every vial.

Built in Australia, held to clinical standards

We started Nexxgen because the research-peptide market was full of unverifiable claims and inconsistent quality. Researchers deserved better than a label they couldn't trust.

Every compound we ship is synthesised in Australian facilities and independently tested for identity and purity. The result is material you can stand behind - lot after lot, with the data to prove it.

Lot NX-2604 matched the COA to the decimal, 99.4% on the HPLC trace. First supplier I have re-ordered from without hesitation.

Ordered BPC-157 and TB-500, both dispatched next day from AUS, cold-packed. The purity data was on the vial, not just the website.

The lot-lookup tool sold me. Punched in my number and got the signed COA plus retention chart. That level of transparency is rare here.

Marcus T. Marcus T. · VIC · Verified

GHK-Cu arrived exactly as described and reconstituted clean. Endotoxin results were on the report, no other supplier gave me that.

Priya K. Priya K. · VIC · Verified

Subscription for my NAD+ saves the reorder hassle and a bit of cash. Packaging discreet every single time.

James W. James W. · VIC · Verified

They actually name the auditor (Sigma Labs). Small thing, but in this space it is the difference between trust and a gamble.
