I have been using peptides for a while…

I have been using peptides for a while now so I was weary of changing suppliers, but peptidology was half the price. I ordered it and got it the next day. Which was awesome. It came packaged great. I noticed that it was a little more viscus. And contacted support, which answered me immediatly. They walked me through the issue and why and how to resolve it. They were quick and addressed my concerns. I appreciate a company that has a live person helping you through, and making sure youre happy.

Great Customer Service

Made my first order with Peptidology…received my order promptly but the vial looked damaged . Contacted CS and quickly was sent a replacement order no questions asked !
But! FedEx delivered to the wrong house. With no help from FedEx at all other than them saying the package was delivered - Zero follow up from FedEx.
Contacted Peptidology not expecting much since they had already sent a replacement order. But they again replaced my Pep and switched delivery companies. Received the 3rd replacement quickly with no hiccups.

Cannot say enough about their great Customer Service.

BLOWN AWAY BY THIS COMPANY!

Ordered five vials of different peptides on Saturday. Site says would ship next business day and should arrive Wednesday. Nope. Shipped Saturday and arrived Monday!! Ordered wolverine, GLPs, one lesser known for cartilage damage.

Their tirzepatide is no joke! Started back at 2.5mg and it began to kick in within 24 hours. I have been on compounded GLP2 through 3 different companies and lately (last 6 months) nothing worked like two years ago! They are watering them down out there! I was spending $100s/month on crap!

Chose PEPTIDOLOGY bc of reviews and their immediate reply to a question before I ordered. Their GLPs are the real deal and the wolverine stack erased my hip/groin pain in two days! I had recently popped something after hiking and it left me limping - second day and pain was gone. Not subsided - gone!

AOD9604 is not well known but I’m starting it for cartilage help to try and put surgeries off a few years. I’m 51 and have severe osteoarthritis in both thumbs and knees are damaged from skiing and FIVE surgeries! I’m aiming to be the bionic woman 😉 and I’m doing my part to stay active and not rely on pain pills. My orthopedic surgeon was 100% onboard with peptides and complained that bc of the FDA pulling them all back he can’t help but he 100% believes in their efficacy! Enough said - peptidology.com has a long standing customer in me as long as their quality doesn’t change!! “Thanks!” Just doesn’t say enough!

Reply from Peptidology

Hi M Trr, So sorry to hear you didn't get the delivery. Although our carriers are reliable, we usually get a lost package once every 200 or so shipments.

Could you please give me (Josh) a call? The office number is 480-974-4660. You can also email us at hello@peptidology.co with your order number and let us know the package didn't arrive.

We'll get you fixed up.

Thanks, Josh

I Ordered my first Peptides from Peptidology for my husband that’s been wanting to lose weight. I ordered Retatrutide and let me tell you this product works wonders. He’s already down 30 pounds in less than two months. Their product 100% pure and when I have any questions or concerns, they have great customer service. A very great reputable company. I will continue to order again.

Fast Shipping!

Website was easy to use. They have a good selection of peptides. I was super impressed with how fast the order was processed and how fast i received my shipments! The products have all been of good quality, meaning they worked and there were no negative side affects. The only thing i would ding them for is the peptides are hard to draw out with a needle some times. I dont have this issue with peptides from other sites i order from. I dont know if it is good or bad (is it super air tight?). Anyway, I always put in air at the same dosage that i am drawing out, but struggle to get the dose at times. Overall, i am very pleased and will continue to order from them for the speed and quality!!

Amazing product unbeatable service and pricing

With so many un reputable pharmacies out there and sub par products online vendors, i was so hesitant to jump in this new wave of medicine. But after speaking to the staff and becoming better informed on my own health i can promise you i will never go anywhere else. The product has shown amazing results, kept me from getting surgery. Everything is always delivered on time and the prices are better then anyone in the nation. 100 percent recommend this site great great place to do business
