Company details
Written by the company
FITSKNS Peptides is a Texas-based, family-owned company built on transparency, trust, and integrity. We started FITSKNS to bring clarity and accountability to an industry that often lacks both. Our focus is on high-quality research peptides, supported by third-party testing and accompanied by Certificates of Analysis so customers can independently verify purity and quality. We believe trust is earned through transparency, not marketing claims. As a family-owned business, accountability is personal—customer service is never outsourced, and when you reach out, you’re speaking directly with real people who stand behind what we offer. We also prioritize education and access to information, providing resources to help customers better understand research materials and processes. At FITSKNS Peptides, we operate with integrity and are committed to earning your trust with every order.

Appreciate that a lot. Thanks for the support and for recommending us.

FITSKNS provides support beyond your order. The Skool app is full of resources including a classroom with information on each peptide, the purpose, how to dose, and other important information. There’s also an informational thread that includes topics on peptides. You can also message your questions where feedback is provided. When starting peptides education and communication are not keys to a successful experience. FITSKNS provides both plus much more.

Absolutely amazing experience with FITSKNS Peptides!
From start to finish, everything exceeded my expectations. The quality of the products is top-tier, I’ve noticed real, visible results in my skin, energy, and overall wellness. What really stood out to me was the consistency and reliability. You can tell they truly care about what they’re putting out and the results their customers get. Shipping was fast, packaging was professional, and everything arrived exactly as expected.
If you’re serious about peptides and want products you can trust, FITSKNS is 100% worth it. I’ll definitely be a repeat customer!

Passionate Company
This is my second time ordering research supplies online and my experience with Fitskns has been 100 times better than my first experience with another small company. The owners of the company seem passionate about their research and in helping others with theirs. They even offer group support with research methods and current research information on all of the available treatments available for testing in a customer community group they have created. They definitely go above and beyond to support their customers. If you are about to start your own research and don't know where to start I highly recommend Fitskns. If you are researcher with experience just interested in getting high quality research materials to use in your research I highly recommend this company as well.

Luck was on my side!
I’m so lucky that this company came up on my FYP! I was new to everything and honestly didn’t do much research on vendors before I ordered. I now know how many fakes and scams are out there but I can say that FitSkins is 100% legitimate!! Again I really lucked out!! I’ve placed three orders now and the communication is on point, if you ever need to reach out, you they are so quick to respond and you can tell it’s not some auto response which is so nice. Shipping is fast and we’ve had zero issues with product!!

Good customer service, bad personal experience with reta
The personal is really nice and effective to fixing problems like when they sent me the wrong product, instead of reta they sent me tirz, immediately sent me the correct item and a shipping label to return wrong product. Now to the problem, I come from doing research with other companies and have had results but I liked that I saw faces to this company so I chose to change and try some of their products. There reta is the problem as I cannot honestly tell with the tesa. I felt absolutely nothing with reta at 2 mg, 3 mg and 4 mg doses. I came from 2 mg elsewhere and could tell it was working within an hour. I felt absolutely nothing from their product so don’t know why or if their testing is as accurate as portrayed. Just an honest review because i would have liked to know since we are researching these items on bodies and that’s important. Just be careful. Stay safe! Hopefully it was just a bad vial and everybody else has gotten normal ones because all the good reviews.

Thank you for taking the time to leave your feedback. We’re human, and while mistakes can happen, we work quickly to make things right when they do. In your case, once the shipping error was identified, we immediately sent the correct product, provided a return label, and issued store credit for the inconvenience.
Regarding the Reta, we do want to clarify that this review was posted after the product had been used for less than two weeks. With Reta, it’s common for effects to take 4+ weeks to become noticeable as the compound builds in the system and the body adjusts across all three receptor pathways. Individual experiences can also differ, especially when transitioning from another source or protocol.
We also want to share that this is the first feedback we’ve received questioning effectiveness with this product. All batches undergo third-party testing, and quality and consistency remain a top priority for us.
We appreciate the honest feedback and always encourage customers to reach out directly so we can review any concerns and help work through them together.
