This is a vendor review submitted by brithus on PeptideCritic.com. Rating: (5/5) Review I have ordered from them many times. I appreciate that their products are tested through Janoshik which makes results easily verifiable. In addition to KLOW, I have also purchased their DSIP, Pinealon, Thymalin, Thymosin alpha 1, Oxytocin, Epitalon, FOXO4-DRI, LL-37, SNAP-8, Cartalax, Selank, Semax, Ipamorelin, Sermorelin, & NAD+. Every product has been top quality and shipped quickly with receipt in about a week at maximum. They are one of my top vendors. Only complaint is that they do not carry P21, PE-22-28 or SS-31 but most vendors don't so I didnt consider that in my rating. Highly Recommend!

Their testing is thorough and transparent. Prices are very competitive. No issues with quality either. I like that they post articles and have some educational information on various peptide topics.

This is a vendor review submitted by pc.envy on PeptideCritic.com. Rating: (5/5) Review Glad I stumbled on them and was able to get anything I really needed. Testing to me is huge and they seem to do it all, more so than other vendors. Shipping was super quick and prices were fair with discounts etc... I've ordered 5 times already and each time it's been a great experience. It's hard to find this kinda overall quality and value for singles IMO.

5.00/5 | Reviewed November 16, 2025 Peptide: CJC-1295 + Ipamorelin I've ordered from Peptide Crafters on at least 6 different occasions. So far, every order has been sent promptly, filled correctly. When I had questions regarding an additional to an order they were prompt with their response. Also, the results on body composition of my test subject has seen noticeable improvements, albeit slow and steady. I plan on using Peptide Crafters again.

5.00/5 | Reviewed November 15, 2025 Peptide: CJC-1295 + Ipamorelin I've had the pleasure of purchasing peptides from Peptide Crafters 6 times at this point. So far, excellent, prompt service. My orders have been correct and sent promptly. As an informal experiment I ordered Melanotan II to see if these peptides worked. Well, about 8 days later my research subject was VERY tan. Lol. I have also noticed changes in my research subjects body composition. So yes, the peptides i ordered are working. CJC-1295/Ipamorelin, and Tesamorelin along with IGF1-LR3 have all been researched thus far with satisfying results.

5.00/5 | Reviewed September 21, 2025 Peptide: Tesamorelin They maybe in middle of road for pricing but their testing goes beyond others.
