Will only get my research supplies from CertifiedPep. Very reliable and fast shipping
Always good product and shipping no problems.
Ording peptides has never been so easy before. The process is smooth. It doesn't take long to get them to me. And I love all the promos i get on the weekends and holidays. Makes it very affordable.
Jason, the owner is great to work with. His GLP 1 really worth!!
Enjoy working with Certified Peptides. All you could ask for! Fair pricing, transparent and quick delivery. Thanks
Delivery is on point, the peptides seem to work great. Only problem I see is the rubber stopper on top. You need to get the syringe exactly in the middle and go straight in, no play either way, or the needle doesn't hit the liquid. Would like to see a change in that.
I have ordered from this company several times and will continue to!
Reta is really good.Like the quality I compared to other other vendor was not as good.Like the customer service
Easy ordering process and quick shipping.
I have tried other sites and Certified has won my trust and all future business. When I started the journey into this area, I had no real idea where to start or who to trust. I tried several other options. Believe me, there is no need to search anywhere else but here. The selection and speed of service is unmatched.
I trust their peptides are better than others. They are easy to work with and always deliver in a timely fashion.
Very high quality peptides. Excellent customer service & fast delivery. Overall a great company
Hey Jason. It would have been a 5 but I need to use the peptide first. Great service and thank you for correcting the errors in the order. Kindest regards Tim
The GLP three has been a really good product. I’ve lost about 45 pounds in about 3 to 4 months and really haven’t had any side effects.
I’ve been very happy with this company. The products have provided great research benefits. The only issue I’ve ever had is my product being out of stock once and having to wait an extra week, but the shipping is fast and the customer service is great. Highly recommended.
I started resarching Tirzepatide and Certified Pep is the real deal! I have to force myself to eat because I have no appetite even on the lowest dosage. They have fast shipping and the COA is available by scanning the QRS code. I have purchased again after my first shipment.
This is a great company with wonderful customer service. I have been using them for a year and a half.
I have been with Certified Peptides for close to a year now. The support, quality and swift delivery is what keeps me committed to this company. I would highly recommend this company. Oh did I mention the testing, numerous American based testing. Each delivery comes with a QR code that shows the testing score. No stress, no problem. Once signed up for email and text messages you will get discounts and access to all the products. Also frequent questions and answers. No guessing. I have personally talked with the owner Jason. It’s nice that Cert Pep is still invested personally with its customers.
Product seems to be quality. Love the COA's and the dosing suggestion. Delivery is outstanding and the discount sales, I really appreciate as this can be expensive For a senior citizen.
Great products, fast delivery, great service. I will be back!
I have been thrilled with my experience with Certified Pep! The product information, ordering process, shipping and communication are stellar. I wouldn’t purchase peptides from anywhere else.
Quality is fantastic and Customer Service is top-notch. They’re very responsive and client oriented. That’s hard to find in the peptide business.
I love certified pep! I referred 2 of my friends and they are using the products too. I have also recommended certified pep to my patients. I am having great results! The customer service is also great!
I have made several orders. Everything always arrives within days after ordering. They have discount codes often. Every time I leave a message, the ladies respond almost immediately. No issues as of yet. I currently have things in my cart now, just waiting for the next discount code.
