Peptide Pros

Second time ordering BPC-157, same fast shipping and the powder looked clean both times. Packaging is basic but does the job.

Prices for MK-677 are great and shipping is fast when they have it. Half the time the thing I want is out of stock though.

Order was fine but took four days to hear back when I asked about a tracking issue. Product arrived eventually, vials intact.

Several orders in, shipping is always fast and pricing beats most. CJC-1295 came sealed and clean. The checkout payment options are the only weak spot.

Quick turnaround, ordered Friday got it Tuesday. Ipamorelin vials full and properly labeled. Good rewards points too.

Prices and shipping are good. My only gripe is the COA they provided looked like a UV report, not the HPLC they advertise. Product itself seemed fine.

Fast, well priced, vials sealed and labeled. BPC-157 reconstituted clear. Will keep ordering.

Half the things I want are always sold out. Ordered TB-500 finally when it was back and shipping was quick at least.

Long time customer. Ipamorelin and sermorelin consistently good, vials full, powder clean. Wish they took cards but otherwise solid.

No frills, just a bubble mailer, but everything inside was sealed and intact. Shipping speed is the strong point here.

Cardarine liquid and MK-677, both well priced. The bulk tiers save real money if you order a lot. Came in two days.

Ordered GHK-Cu, the COA they sent actually matched the lot number this time. Shipped same day. Happy.

Peptide Pros has become my preferred source for tirzepatide after testing samples from five different vendors. Their product consistently comes back at 98.5-99.1% purity which is exceptional. The lyophilization quality is professional grade - reconstitutes perfectly clear every single time with zero particulates. COAs include full mass spec analysis not just basic HPLC which gives me confidence in what we're actually getting. Shipping averages 3-4 days with excellent cold chain management. The vials are pharmaceutical grade with clean crimps. Customer service is knowledgeable and responds within 24 hours. Pricing is higher than budget vendors but significantly cheaper than the premium boutique suppliers. My lab has gone through 15+ vials over the past 4 months with zero quality issues. The website could use better mobile optimization but that's a minor complaint. Highly recommend for serious metabolic research where peptide integrity actually matters.

They sent me an email asking for a review so here it is. Got tirzepatide and CJC-1295 about two weeks ago. Both peptides arrived fast - ordered Wednesday, had them Monday. Packaging was excellent with gel packs still frozen solid. COAs were included and showed 98.6% for tirz and 97.2% for CJC. Good stuff.

Shipping was fast and the BPC-157 looked fine, but one vial in my order was noticeably underfilled compared to the others. Support offered store credit eventually.

Third order this year. CJC-1295 and ipamorelin both arrived quick, vials properly capped and labeled. Prices stay competitive.

Tried to pull the certificate of analysis for the RAD-140 liquid and the link just refreshed the page every time. Not great when testing is the whole point.

Honestly the best prices I've found for sermorelin. Free shipping over $150 and it showed up in two days.

TB-500 came lyophilized okay, cake intact. Packaging was pretty plain and one label was crooked, but everything was sealed.

Was asked to write this after my recent purchase. Ordered tirzepatide and TB-500 for two separate research protocols. Both arrived within a week properly packaged with temperature monitoring strips showing they stayed cold the whole time. The tirzepatide COA showed 98.9% purity with comprehensive testing data. TB-500 came in at 97.4% which is acceptable for our purposes. Reconstitution was smooth for both peptides. Customer portal is easy to use and reordering is quick. Pricing seems fair compared to what I've paid elsewhere. Only complaint is their minimum order threshold is a bit high if you just want to test a single vial. Overall good experience and I'll order again when we need to restock.
