Retatrutide not working
I too thought I was tripping when I read a review on here from Dec 9th that their retatrutide was not working. I increased my dose and still can barely feel anything. I too bought the 3 kit vials and I am disappointed. I thought it was just me at a stall already, but thanks to another reviewer I’ve concluded it just isn’t me and is the product itself. From reading Peptira’s response to the other reviewer, it sounds like they will blame customer diet and etc. Will not be shopping here unless they make it right. I’ve had way better results with my other vendor, tried this one since they had a sale.

8 of the 10 vials had lyophilized powder broken
I ordered Nad1000 x 10 vials 8 of the 10 the lyophilized powder was shattered or chipped which could indicate a problem in the lyophilize process. Wrote the company and they responded it was fine. Now I have to pay for testing and lose a vial of product to verify its fine. Peptira sells you insurance and doesn't stand behind it. I suggest you go to another peptide company. Peptira I buy thousands of research peptides a month and I really wanted you to be my supplier but I can not do business with you when you refuse to stand behind your insurance. A simple google search will explain how broken pucks could be a quality issue.. The truth is you don't know anymore than I do and it needs to be tested. Profits should not come before safety that is how people could die.. Facts

Very good and very well
Questionable Potency Compared to Other Vendors
I am not impressed with Peptira's retatrutide- it feels completely different than a much less expensive and fancy vendor. I even upped my dose with the Peptira reta and felt nothing. I paid almost $200 for 3 vials and am sorely disappointed. Needless to say, I am staying away from these fancy overpriced sites and going with the more modest ones. I really hope Peptira can rectify my situation, as I see I am not the only person having issues with potency. I have also spoken with other people who have purchased retatrutide from this company and have a similar experience. Hopefully this company cares about making it right over profit. A "thanks for the suggestion" is far from improvement. Check out MRP (modern research peptides) and CoffeeandPeppers for better quality retatrutide at a much lower price, without all the gimmicks. I cannot speak to anything else from this company as I have only ordered the retatrutide. I will come back to update my review after I speak with the company. Thanks for reading.

Will order again!
Placed my first order from you and it was delivered promptly and with great communication!
Reliable, transparent, efficient.
Peptira has shown time and time again how transparent they are in every aspect of the business; from the way they handle the ins and outs to the COAs for every product. They are quick to answer questions and to resolve issues. By far some of the best customer service I have received and that’s coming from someone who has been in customer service for 20+ years.
Trustworthy quick and reliable
I have been skeptical to order from companies that are on the newer side. These days new companies are popping up left and right in this particular business. After seeing numerous videos put out by the owner and receipts backing his claims I decided to go for it. I couldn’t be happier. Customer service is top notch, the quality of product is excellent and as advertised. Shipping is FAST
Peptira, keep it up!
It was delivered in proper packaging to reduce risk of breaking during shipping.
I liked their prices over competitors although the peptide I got was 97%, when on the website it said 99% purity for the vial.
