Awesome customer service
Awesome customer service, my order was in limbo because of a storm that hit there area. They reached out several times giving me updates where the package was. After two weeks with the package in stand still they went and reshipped a new set of peptides at no cost, also gave me a future $25 for my next order, this was out of there control but they went above and beyond to get me what I ordered.

Really great experience
Really great experience! Ordered GLP3 (Retatrutide). It was the best price, incredibly easy to order, and everything arrived in 48 hours just like they advertised. Packaging and materials were also fantastic! I was nervous about my first experience dealing with peptides. I will be ordering from peptidecrafters from now on!

Echoing what most folks here have said
Echoing what most folks here have said, cannot recommend them highly enough. The customer service is so prompt and so helpful. The prices are fair and they have such a huge variety. I especially like the transparency with their testing in all the different things they test for. That is what makes them worth it for high quality research. In an industry where it’s easy to be shady, these guys are different. Have placed 5 orders so far and will be ordering again soon!

Ordered the Kit (nice storage container included):BAC & 14 research items. Website user friendly and payment with c/c was simple. I paid the extra $ for insurance/delivery and was able to track my shipment and it arrived quickly. Every aspect of my order from start to finish was perfect and the product was as expected. t was nice to see the research product had labels that matched the COA).

I had the best experience with Peptide Crafters! So grateful for their above and beyond outstanding customer service and excellent research products. I had some urgent research due to a serious injury right before the holidays and the Peptide Crafters team really went the extra mile to ensure I received my order right away with fast shipping and were very generous and helpful in working with me to accommodate my needs. I have placed many large orders with Peptide Crafters and will continue to make them my go to source for research peptides for myself as well as my friends and family! Thank you so much! 🙏💓

Good price Reliable source and Good product
Trying to find a reliable source and reasonable price is a frustrating process when it comes to peptides. The reason I am leaving this review is the service, cost and product from this company have been good. I have order a few different stacks. 11 different peptides over the last 6 months. I compared prices to about 10 other recommended companies by spreadsheet and they are continually the best price. The peptides have been effective and no issues with product, payment or delivery. Placing another order today, ran price comparisons and they are still competitive and I can trust product. crafters10 gets you discount every order.

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.

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).

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.

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

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!
