SLU-PP-332 was out of stock
Brenda A.

Wanted to grab SLU-PP-332 but it was unavailable for a couple weeks. Ended up ordering GHK-Cu instead, that part was fine. Wish they kept stock more consistent.

Quality concerns with recent order
Blake Russell

Have been using Atlas for about 6 months and this latest order was disappointing. Got Semaglutide and CJC-1295 for research. The Semaglutide vial had some particulate matter floating in it even before reconstitution which is concerning. The CJC looked fine but when I contacted customer service about the Semaglutide issue they were slow to respond - took 5 days to get back to me and then just offered a replacement without much explanation. The COAs both looked legitimate with good purity numbers but seeing visible particles makes me question the handling. Previous orders from them were flawless so not sure what happened this time. Shipping was standard 6-7 days. Hoping this was just a one-off quality control miss but it's made me more cautious.

support is slow to reply
Catherine K.

Had a question about stock and it took three days to hear back over email. Order itself was fine once it shipped.

decent but plain packaging
Janet Q.

No complaints about the actual vials, sealed and labeled correctly. Just a plain bubble mailer, nothing protective beyond that. Got the job done though.

COA wasn't batch specific
Cynthia D.

Product itself looked fine, lyophilized cake intact. My only gripe is the COA they sent looked generic and didn't match my lot number. Asked support about it and got a slow reply.
