**★★★★★ Testing you can actually trust** — Oct 18

The verified testing standard is the whole draw for me. Every batch gets HPLC and MS and it is posted publicly. Epithalon order this time, quality was spot on.

**★★★★★ No surprises, exactly as listed** — Oct 12

Tirzepatide ordered, exactly what the listing described, COA matched the lot and shipping was two days. Will be back.

**★★★★★ Would recommend to anyone** — Oct 6

Clean vials, accurate fill, scannable COA, domestic two-day shipping. This is how a vendor should run.

**★★★★★ any word on them coming back** — Jul 21

Used Peptide Sciences as my default for a long stretch. Packaging was always clean, ice packs still cold on arrival, COA in every order. Sad to see them shut down and just checking if anyone has heard whether they'll reopen.

**★★☆☆☆ expensive and then just closed** — Jul 2

Honestly the writing was on the wall. Prices crept up, customer service got slower and slower to answer emails, and then one day no more site. Decent vials when they arrived but I wouldn't call the whole experience worth the premium they charged.

**★★★★☆ solid run while it lasted, anyone know a replacement?** — Jun 14

They were never the cheapest and the COA was always their own in-house testing rather than a third party, which bugged me a little. But shipping was quick, the website was easy, and stock was reliable for a long time. Now that they're gone I'm a bit lost on where to reorder, hoping someone here points me somewhere with the same consistency.
