Your company is amazing I wish I would have found y'all sooner, last year I had major back surgery I have 4vrods 16 screws to hold the spine in place. I was using sermorelin then I found y'all and switched to Tesamorelin. This was my 21st surgery I have lost 18 pounds my body has transformed so much in 64 years old, I can tell you I look and feel like I'm in my mid 30's. I have a friend who's going to start using your product I absolutely love this product and your company is extremely fast and offer so much and great prices. I wish I could be your poster boy lol. Thank y'all so much Robert Delicino

I received my order very fast. They package the smaller viles in small plastic containers to keep them safe for travel. I will definitely be ordering again from this company since they do third party testing.

Great products, fast shipping, so easy! My only suggestion is to use slightly shorter labels so you can see the liquid level through the side of the vials.

I was nervous about my first order but it ended up being a great choice. I ordered 1 vial of T30 and it was here in 2 days. The results have been fantastic and I will be a regular customer for as long as this site is up and running. I told a work friend and he ordered a few days ago and was very pleased with the price and shipping time. This place is great in my humble opinion.

Have been using another company's peptides and that company's customer service is non existent and when you do get anyone they are very arrogant. Certified-Pep jas been 100% easier to deal with, pay and recieve my order in a much better timely manner. And a better price! A home run in my book.

I contacted customer service before placing order due to a reconstitution/strength question and they responded within a few hours. My delivery was on time and I really appreciated the business card and the barcode on my vials for lab information. Will definitely order again!!!!

In the wild and woolly world of peptide options, it can be overwhelming. I truly wish that I had found Certified Peptides first in my journey to find a reliable and TRUSTED supplier. If you are a first-time shopper looking at options, seriously, look no further. Jason has busted hump to build the company. I witnessed some of the growing pains and the never-ending battles Jason has endured to supply us with reliable, trusted products. The staff is super helpful, order fulfillment is crazy fast, and shipping is typically within a few days. Don't hesitate to buy from them! Certifed Pep: The real deal.

Ordered ipamorelin 10mg and bac water. Was extremely surprised at how fast delivery was, notifications on every step in the road to my door 👍 But in the order was a card for someone who specializes in this industry, which shows me a level of care that exceeds expectations. Will definitely keep using certified peptides.

Review ★★★

I’ve been asked for a review too early. I’ve only been researching for one week and have zero results so far. As of now, I’m 50/50 on purchasing again from Certified Pep. My next research will be with Reta but will probably look elsewhere. I will say, incredible shipping and company to do business with.

The prices already expensive and you charge protection product. You are responsible for packing them right. Also you charge for shipping.
