Real feedback from researchers and customers. Every review is tied to a verified purchase.
purity good, label has typo
Purity is fine, COA matched. Small thing — vial label spelled the lot number with a lowercase L instead of a 1, made me look twice. Maybe just a sticker thing. Otherwise no complaints.
good product, packaging was a little bent
vial was fine. box looked like it lost a fight. peptide reconstituted clean tho. 4 stars only because the box arrived crushed but contents were perfect so probably a fedex thing not them
exactly what i ordered
ordered tues, arrived friday. coa was right there in the box, purity 99.1. ran my own hplc in lab and it lined up. nothing more to say.
fast delivery, sealed tight
shipped same day i ordered. ice pack still cold when it got here in arizona. not bad
Solid lot
Switched from another supplier after they ghosted my COA request twice. 22EXO sent it before the package even shipped. Lot 24-08-BP157. No issues with reconstitution, no cloudiness. Will reorder.
academic lab use
Bought for a wound-healing assay. Lyophilized cake was intact, dissolved in BAC water with no swirl-time issues. Mass spec matched the spec sheet identity peak. The cost difference vs. our previous vendor is noticeable.
Repeat customer now
third order. consistent. consistent. consistent. that's the whole review honestly
Better than the other guys
Used to buy from one of the bigger names. Their last lot came in with visible discoloration in the cake — 22EXO's was textbook white, fluffy. Going forward this is where I'm ordering. The honesty about FOR RESEARCH USE ONLY also matters.
tried to deliver when i wasnt home
fedex left a slip. had to drive to the depot. otherwise fine product i guess.
Good quality, solid COA
Purity checked out at 98.7% on our end. Only minor note is the vial labeling could be clearer. Product itself is excellent.
Fast shipping, clean product
Arrived well-packaged in 2 days. Reconstituted cleanly with no visible particulates. Very satisfied.
Exceptional purity
Consistent batch-to-batch quality. HPLC results match the COA exactly. Our lab has reordered three times now.
