Peptide Sciences

Years as my one and only vendor for ipamorelin and BPC-157. Never had a reason to look elsewhere. Heartbroken they've shut down.

Ordered CJC-1295 and ipamorelin from them for years without a hitch. Genuinely the most consistent vendor I had. Going to miss them.

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.

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.

TB-500 shipped same day I ordered. Powder looked great and the COA matched. Hard to beat the turnaround.

Reordered IGF-1 LR3. Same fast domestic shipping and clean product I've come to expect from them.

Our neuroscience lab ordered Semax, Tirzepatide, and Selank from Peptide Sciences for ongoing cognitive enhancement studies. Everything about this order was professional and high-quality. Shipping was fast - 4 days to the Midwest. All three compounds arrived in pristine condition with proper cold chain management. The packaging was among the best I've seen from peptide vendors - pharmaceutical-grade vials, clear labeling with batch numbers, and comprehensive COAs showing purity levels of 98.7%, 97.9%, and 98.2% respectively. We performed our own verification testing and the results aligned perfectly with their documentation. The Semax and Selank have been particularly impressive in our behavioral assays, showing consistent bioactivity across multiple trials. Customer support was knowledgeable when I had questions about optimal reconstitution procedures for the Semax. Pricing is fair considering the exceptional quality control. Will continue using them for research purposes.

Been using Peptide Sciences for my research work for about 8 months now. Just received my latest order of Selank and the CJC-1295 + Ipamorelen combo. Everything arrived within 4 days, well packaged with ice packs still cold. COAs are always included and easy to verify. The Selank quality has been consistent across three orders now. Pricing is competitive and they often have sales. Customer service answered my questions about reconstitution within a few hours. Highly recommend for research applications.

Years of ordering TB-500 and CJC-1295 here. Quality and shipping have always been on point. USA made.

Ordered GHK-Cu for our dermatology research program and couldn't be happier. Product arrived in 5 days with professional packaging and complete documentation. The COA showed 98.4% purity from a reputable testing lab. Reconstitution was smooth and we've been using it for two weeks now with consistent, reproducible results in our collagen synthesis assays. The vial sizing is perfect for our needs and the price point is reasonable for the quality. Customer service answered my questions about storage stability within a few hours. Will definitely reorder when we need more for research purposes.

Order placed Monday, in hand Wednesday. CJC-1295 with DAC, COA in the box. Can't complain.

Several orders of BPC-157 now and the quality never changes. That consistency is why I pay the premium.

MK-677 capsules arrived fast and exactly as listed. Easy reorder, will keep coming back.

Been ordering TB-500 and BPC-157 from them for over a year. Consistent every time, never had a bad batch.

Ordered BPC-157 in the morning and it shipped same business day. Domestic shipping with these guys is genuinely quick.
