What Customers Mention
Ordered from these guys for years and never had a bad box. Vials always filled right, packing was tight, COA tucked in every time. Gutted they closed up and still looking for anywhere that comes close.
We used peptide sciences for years, but since they went down we moved to Oath peptides (Oath Research) And couldn't be happier. The support is actually much better, they actually answer the phone. The packaging and overall experience just feels better. All that said, we'll miss them. They set the standard.
Two months since they closed and I still haven't found a vendor I trust like I trusted them. Open to recommendations for CJC-1295.
Placed one last MK-677 order days before they went dark. It never arrived and support has been unreachable. Just disappointing.
Years as my one and only vendor for ipamorelin and BPC-157. Never had a reason to look elsewhere. Heartbroken they've shut down.
Long-time customer here. Their TB-500 and CJC-1295 were always clean and shipped fast. Sad they're done, end of a good run.
Had a BPC-157 order in when they closed. It never went out and nobody has answered a single message since. Frustrating way to lose a customer.
Used Peptide Sciences for everything. Now they're gone and I have no idea who to trust for MK-677. Hoping the community has suggestions.
Ordered CJC-1295 and ipamorelin from them for years without a hitch. Genuinely the most consistent vendor I had. Going to miss them.
My order was still processing when they shut down. No shipment, no refund, no reply to any of my emails. Just radio silence.
These guys closing leaves a big hole. Anyone have a reliable alternative for BPC-157 with shipping this fast? Feeling a bit lost.
Been my go-to for TB-500 since I started. Sad to see them shut their doors after all these years. They set the bar for domestic shipping.
Website's been offline for over a week now. Used them for MK-677 a few times. Just neutral confusion at this point, wish they'd say something.
Placed an order for ipamorelin right before the site went dark. Never shipped, no tracking, and my emails have gone unanswered. Out the money.
Five years of ordering BPC-157 and CJC-1295 from these guys and now they've closed. Best source I ever had, never a single bad order.
Tried to reorder TB-500 and the site has been down for days. Anyone know if they're actually gone or just having issues?
TB-500 shipped same day I ordered. Powder looked great and the COA matched. Hard to beat the turnaround.
No issues with my ipamorelin order and shipping was fast. Still, I'd trust them more if the COA came from an outside lab instead of in-house.
GHRP-2 order arrived in two days, sealed and labeled right. Prices are steep but the product is consistent.
Product quality was good and shipping quick. Email support is slow though, took several days to hear back on a simple question.
