Vendor Reviews & Orders

I noticed, at least in my browser, their main shopping list displays only 48 out of 74 listings. It doesn't load the rest. I though that's all they had but if I go to another page (research-peptides), I can see the rest of their products. I wonder how many people missed that.

@pep_researcher I used a Citi Visa card and it worked with no issues. I think I tried a Mastercard back a few months ago and had a problem so just moved on to Citi Visa.

They ended up giving me a store credit or offered a Zelle payment. I took the credit

I havent gotten glp3 from crush but im currently running a 10 pack of cardiolipin repair and also on my third vial of VIP. The reason I did this was because awhile back cardiolipin repair seemed to be a major mover for my blood pressure. Figured I would try running it again with VIP and see what happens. Long story short im getting a taste of what its like to not constantly sweat from being pressured up. I like it. Purchased both from Crush. Excellent pricing on the 10 pack also. Thumbs up!! Keep it up Rory. Dude is always sold out of a lot of stuff, but i can see why. This has become my backup to Nexaph. Reminds me of Verlander and Kuechel when Houston won the series then they took it away. Solid 1-2 punch to lead me to the promise land.

This is a vendor review submitted by WBWright on PeptideCritic.com. Rating: (5/5) Review A friend of mine referred me to PX Peptides and I’m so happy he did. I have bought Peptides from multiple companies over the last several years and this is the first company where I feel I have a connection with the owner, and understand his mission and what he strives to do in regards to not just providing a high quality product at a great price point, but also helping people find happiness through health. As a business owner myself, I understand the fine balance between maximizing profits and revenues, and leaning into high customer service. Over the years, I have learned that the more you lean in the customer service, the more profits and revenues tend to take care of themselves. That’s exactly how I feel Px Pepetudss conducts all of its business. I have no hesitation whatsoever in referring PX Peptides to all of my friends and family.

@kristophermatyas While i agree and have ordered dozens of peptides from Certified pep, their prices are ungodly expensive, just compare to Nexaph, which i'm finding are far more expensive from others... So guess all is point of view!

I’ve placed multiple orders with this company since January, and they’ve earned my trust every time. My latest order(much needed kit of TB) was placed on July 25th and delivered by July 27th during their Birthday sale. The customer service is consistently fantastic, and the products work as expected, no issues to speak of in my experience. A dependable company in my opinion.

This is a vendor review submitted by researchpeptides99 on PeptideCritic.com. Rating: (5/5) Review Peptidology is just excellent in their quality control, product testing (consistently use same ISO certified lab and full testing), and customer service. Been using them for a while now. They are slightly pricier but I don't mind paying for quality, mature ops, and great customer service.

This is a vendor review submitted by The masked Pepper on PeptideCritic.com. Rating: (5/5) Review Pricing is as close to gray as you're going to get without actually going gray so if you're trying to avoid having your address in a database after a customs seizure and want the security of using a credit card, they're your best bet. They test with Jano and if you're in their TG you can volunteer a vial and they'll pay to test up to 3 customer's vials for mass and purity. On top of that there are traditional 3rd party group testings you can join. In addition to that, they wholesale to other resellers so you might already be using their product and don't even know it. They always have 5% off for crypto and occasionally run sales. Two that they just did was 15% off everything which stacks with the crypto discount and 25% off everything if using crypto. Finally, they do have presales on Reta 24/48 and Tirz 30/60. The last one was 33% off the regular price. While I do buy gray also, if I just need to buy a single kit and need it fast, they are my go to. They overfill and the additional cost is worth due to the testing.

This is a vendor review submitted by uxu on PeptideCritic.com. Rating: (5/5) Review Placed this order on Saturday, August 1, 2026. It shipped within 48 hours via FedEx 2Day, which is faster turnaround than I expected for a weekend order. Ordering and checkout were straightforward. Pricing stacked cleanly: a 10% sale price on the 3-vial pack, a 10% discount code, and an additional discount for paying by bank transfer. Final total came to ~$150 including $12.00 shipping, down from a $180.00 list price. The confirmation email itemized every line, so there were no surprises between checkout and the receipt. Packaging was better than average. The FedEx 2Day envelope contained a black bubble mailer as an inner protective layer, and inside that the KLOW vials came in a branded box with a molded 3-vial holder. All three vials arrived intact with no shifting in transit. Product matched the published COA. In use it performed as expected for its stated purpose.

Definitely one I'll be putting on my "DO NOT CONSIDER" list

@emkay Same for me. I originally bought it for the vial labels, but I'm using it for so much more, work, household etc

I'm surprised to find several EZ product pages with broken COA links, although the COAs are there under "Previous certificates". I messaged them about two but also found a couple more just now having the same issue. Their site and product pages used to be quite well maintained a few months ago. What's going on?
