About Phased Research Group
We sell research peptides. We test every lot. We publish the COA before you buy. That shouldn't be unusual, but here we are.
The Problem We Saw
The peptide supply chain is a mess. Most “vendors” are resellers who bought from someone who bought from someone who bought from a lab in China. By the time the vial reaches you, nobody can tell you which batch it came from, when it was tested, or whether the purity number on the label came from an actual lab or a marketing department.
We watched vendors post COAs with no lot numbers. We watched them say “available upon request” and then ghost the customer. We watched them test one vial from a batch of a thousand and call the whole batch “verified.”
So we built PRG to do it the boring, correct way. Every lot gets tested by a lab that isn't us. The COA goes on the product page. The lot number on your vial matches the lot number on the document. If we can't prove it, we don't ship it.
No Weasel Words
We Name the Lab
The lab that tests our peptides is independent and contactable. Not 'in-house.' Not 'a partner lab.' A real lab with a real name you can look up.
Every Lot, Not Samples
We test the actual lot your vial came from. Not a 'representative sample.' Not a single unit from a batch of a thousand. The lot.
COA Before You Buy
The COA is on the product page. No email back-and-forth. No 'available upon request.' You see the purity and lot number before you pay.
Same Day Shipping
Order before 2PM CST, it ships today. Tracking emailed same day. No '3-5 business day processing' games.
Lot Numbers Match
The lot number printed on your vial matches the lot number on the COA. Every time. If it doesn't, something is wrong.
Lyophilized Powder
Ships as freeze-dried powder, not pre-dissolved solution. Pre-dissolved has hydrolysis and oxidation risk. We don't do that.
