**★★★★★ 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.

**★★★★★ great experience** — Jul 22

Epithalon order came packed well and got here in three days. Vials sealed properly, labels clean. No notes.

**★★☆☆☆ shipped slow this time** — Jul 14

I've ordered before with no issue but this round sat in processing for four days before a label was even created. It eventually showed up and the product was fine, but the whole point for me was the fast turnaround. Emailed twice during the wait and only got one reply.

**★★★★☆ my new go\-to** — Jul 8

Third order from them now. Consistent every time and the free shipping over $200 makes bulk orders worth it.
