Highly recommend for excellent service and quality

I completely agree with what many have mentioned; I can't recommend them enough. The support team is incredibly prompt and helpful. Their prices are reasonable, and they offer a vast selection. I particularly appreciate their transparency regarding the various tests they conduct. This commitment to quality research truly sets them apart in an industry that can often be unreliable. I've placed five orders so far and look forward to ordering again soon!

The best

Very fast shipping, best prices I've found, trustworthy lab results, great customer service, and a points system where I can redeem for discounts! Also, you can sign up for their email list to receive a 10% discount on every order. I haven't had any issues since I started ordering from them (approx. 20 orders so far).

I’m genuinely impressed with Peptide…

I’m genuinely impressed with Peptide Crafters! Their transparency and dedication to quality are on another level. I recently read through their solvent study, and it was eye-opening. The amount of detail, data, and care that goes into ensuring purity and safety really sets them apart.It’s shocking how many vendor are selling contaminated or completely fake solvents and research materials. Peptide Crafters clearly takes the science and integrity of their products seriously, and it shows. It’s rare to find a company that backs up its claims with real testing and published studies. Highly recommend to anyone who values quality, consistency, and honesty.

Ashley with the one-star review..

Ashley with the one star probably shouldn't be making decisions on buying research peptides if she doesn't know what reconstituting is or is asking for directions on how to do so. It's for research, and people who are knowledgeable enough to know how to use and handle the product as well as being able to do the minimal calculations for the processes. Everything needed is listed on each item, and if there are any questions you may need to do further research. PHD

Quality, affordable and quick shipping

I have recently begun using Peptide Crafters for my research peptides. The peptides are high quality, reasonably priced, ship quick and safely. I had a shipping issue (my fault) and they promptly refunded my money. That was great customer service. I will continue to use Peptide Crafters with confidence.

I get my Peptides from two different places. This is one of them.

Changed my mind

At first I had great experiences with the company. Recently, I received a vial of BPC-157 that had no vacuum. The company told me that vacuum did not mean much and the product was good. I used it for research and it was contaminated. I tried another vial with the same outcome and contacted the company. I was told that they did not sell contaminated product. Rather than argue and because of negative reearch, I have decided not to use them anymore.

Gold Standard of Tested Research

Honestly you would be hard pressed to find a vendor for your lab research that does well renowned labs and iso certified HPLC for Identification & purity, USP 85 for endotoxins and UPS 71 for sterility. Not to mention all the studies they do for free on important topics. Peptide Crafters (PC) is a Gold Standard in the industry with a very fair price point and shipping. Whenever we need samples of products for our lab, we always can trust PC!
