Their product is tested and safe. It also came super fast, much faster than we will get it from a telehealth and no hoops to jump through as well as way more affordable!

They rock
Order a product was delivered in two days. I’m excited to start it. Everything looks to be on point with quality and with the COAs we will see how the product works but as far as the shipping and how legit they are, it looks perfect.

Hello, based on your review it appears our research-use-only product was used in a manner inconsistent with its intended purpose. All Peptira products are clearly labeled and sold strictly for in vitro and in silico research only.
We have supplied hundreds of thousands of units to laboratories without reports of sterility issues. When adverse outcomes are alleged, they are most often attributable to laboratory handling, preparation, or procedural variables outside of our control.
15lb in 4 months... Meh
Their orders are shipped quickly, emails are answered quickly. The sales help a lot when buying the product.
I'm just debating on whether I continue using or bow out..

I screwed up and ordered the wrong product and immediately emailed Peptira to cancel the order. They wouldn't cancel it. I won't return.

Hello Richard,
Thank you for reaching out. Unfortunately, per our Terms and Conditions, we’re unable to cancel, refund, or accept returns due to the nature of our products. These terms are presented and must be agreed to via a required checkbox at checkout before an order can be placed.
Our records also show that your order had already entered fulfillment by the time we received your message. Given our order volume, our fulfillment team operates continuously to ensure orders ship quickly, which limits our ability to intercept orders once processing begins.
While we understand the frustration, it is the responsibility of the purchasing laboratory to review the Terms and Conditions and confirm order details prior to submission.
You can view the full policy you agreed to here:

Didn't work for me
Haven't noticed any results whatsoever. Ordered 5 Amino. Very disappointed. Now that I'm comparing prices too, I overpaid for what I got. In response to your response: I'm definitely not new to lab protocols and have tested several other companies products. The consensus shows yours had no results. It just is what it is. Nothing else changed except the product. You're not the only company I've gotten products from that simply don't work. It seems like there are alot of companies out there selling bunk products. All I can do is leave honest reviews as to my personal experience. What works for one person, may not work for another.

We’re sorry to hear you’re disappointed. In our experience, a lack of observed results in research is most often tied to other variables within the lab environment, not the material itself. All of our products are third-party tested for identity, purity, net peptide content, and endotoxins (tested twice), and we now include additional conformity testing as well.
While outcomes can vary widely depending on handling, storage, and research conditions, we stand fully behind the quality and verification of our materials with COA's available for each batch including historical.
Thank you,
I’m giving this company 3 stars
I’m giving this company 3 stars. The peptides work very well, and shipping has been reliable with products arriving well packaged and in good condition. However, ongoing inventory issues significantly affect the overall experience. I’ve been waiting a long time for acetic acid to come back in stock, which is a key component for reconstituting certain peptides like IGF. While the product quality is solid, the frequent stock shortages prevent me from rating this higher.

We appreciate the kind words and the honest feedback. We do want to clarify that we have yet to offer acetic acid on our platform since inception. Aside from a small handful of particularly difficult-to-manufacture items (such as AOD and Snap-8), we maintain consistent availability across the vast majority of our 55+ research products.
We’re glad to hear you’ve been happy with the quality and reliability of the products you’ve been able to source for your lab, and we appreciate you taking the time to share your experience.
Quality product and decent price
Quality product and decent price. Been buying peptides from peptira for about 6 months now probably spent about 5 grand here had one order issue and they handled it right away. I also won the 12 days of Christmas give away and got a bunch of stuff including a sweet embroidered Nike hoodie. I will continue to buy from peptira.

I’ve ordered from Peptira about 5 times…
I’ve ordered from Peptira about 5 times now. Customer service is always on point and I truly appreciate that they test every batch that comes in. Putting our safety over anything. There COA’s are resent, not from 2024.
