Core Peptides

Solid all around. Ordered TB-500, came in three days, packaging was secure. Customer service answered my question quick.

Tirzepatide order, my second from them. Same fill, same fast shipping. Glad I found a steady source.

Ordered retatrutide, shipped same day since I beat the cutoff. Showed up fast and well packed.

Four orders in, never a problem. MK-677 and ipamorelin both consistent. Site says UPS but it always ships USPS, minor thing.

Quick shipping, GHK-Cu tested clean, packaging tight. Reordering.

Ordered CJC-1295, KPV, and Tirzepatide for different research protocols. All three came well-packaged and the COAs showed good purity numbers - CJC was 99.1%, KPV at 97.8%, and Tirz at 98.6%. Shipped via priority mail and arrived in 3 days. The only reason I'm not giving 5 stars is the KPV vial had some minor crystallization but it dissolved fine once reconstituted. Their product selection is excellent and covers most of what I need for ongoing studies. Customer portal is easy to use and order tracking actually works unlike some other vendors. Will definitely order again.

Got an email from Core Peptides asking for feedback after my last order. I've been using their TB-500 for various tissue repair studies over the past two months and the results have been consistently reliable. The peptide arrives with proper COA documentation showing 98.4% purity which matches what they advertise. Shipping took about 4 days which is reasonable. Only minor complaint is the vials could use better cushioning in the packaging - one arrived with a slightly loose cap though the product itself was fine. Customer service responded quickly when I asked about reconstitution protocols. Price point is competitive for the quality you're getting.

TB-500 arrived in two days. Tested it myself and came back clean. Will reorder.

Vials came well padded with an ice pack still cold. Appreciated the care given it was 90 degrees out.

Been using Core for my ipamorelin and CJC-1295 blend. Consistent every time, reconstitutes clean.

Ordered BPC-157 and TB-500 on a Monday, had it Wednesday. USPS Priority. No complaints.
