All products are intended for laboratory research use only. Not for human consumption.

Phased Research Group

Research peptides with lot-specific COAs. Every batch tested by an independent lab. No “available upon request” games.

99%+ Purity, Verified

Every lot is HPLC and mass-spec tested by a third-party lab. The COA goes up before the vial ships, with a lot number that matches what's on the label.

No Grading Our Own Homework

We don't test in-house and call it third-party. The lab that tests our peptides is independent and contactable. You can verify the batch ID yourself.

Ships Same Day If You Order Before 2PM

Order before 2PM CST, it goes out today. Tracking emailed same day. No “3-5 business day processing” nonsense.

Why We Exist

The Industry Has a Trust Problem

You already know the deal. Half the peptide vendors online post COAs with no lot number. Others say “available upon request” and never send one. Some ship thousands of vials while only testing a single unit from the batch. A few got caught forging lab reports.

We started PRG because we were tired of it too. Here's what we do differently:

  • Every lot gets tested. Not sampled. Not “representative.” The actual lot.
  • The COA is on the product page before you buy. No email back-and-forth.
  • The lot number on the vial matches the lot number on the COA. Always.
  • We name the lab that does our testing. You can verify it yourself.

This isn't the industry norm. It's our minimum standard.

Every Vial. Every Lot. Every Time.

We publish the COA for every batch on the product page. The lot number on your vial will match the lot number on the document. If it doesn't, something is wrong and we want to know about it.
