I'm a huge fan of Zen! You can really tell they care about their customers by how much effort goes into their packaging, everything arrives safe, secure, and exactly as ordered. Plus, the free sticker... Ver más

I used Zen Aminos a few months ago when…

I used Zen Aminos a few months ago when I was new to peptides and purchased CJC-1295 for a 3-month cycle. Throughout that time, I noticed inconsistencies between the vials I received. Some were clear, while others appeared cloudy, which made me uncomfortable using them.

To their credit, they did replace one vial after I contacted them. However, I was told the cloudiness was likely caused by the quality of the water I used for reconstitution. After learning more about peptide handling and working with a medical provider, I no longer believe that explanation applied in my situation. That response left me questioning the company’s quality control.

Another issue was customer service. The company advertises that they’re available to answer questions, but I rarely received a response when I called, and most email replies were brief and didn’t address my concerns. I also felt that questions about other products were often ignored.

Personally, I didn’t experience the results I was hoping for while using their products. Since switching to physician-prescribed, pharmacy-grade peptides under proper medical guidance, I’ve noticed a significant difference in my results. While that’s only my personal experience and doesn’t necessarily reflect the quality of every product they sell, it has made me choose a different source going forward.

I was also surprised to find that I appear to have been blocked on their social media after sharing my concerns.

Overall, I can’t recommend Zen Aminos based on my experience. The lower prices may be appealing, but I would encourage others to do their research and consider the importance of product quality, customer support, and medical guidance before purchasing.

Thank you for taking the time to share your experience. We genuinely appreciate customer feedback, as it helps us continue improving our processes and service.

First, we want to clarify that Zen Aminos sells research-use-only (RUO) materials. Our products are not intended for human consumption, diagnosis, treatment, or prevention of any disease. Anyone seeking medications or therapies for personal health should consult a licensed physician and obtain products through a licensed pharmacy or healthcare provider.

Regarding your comments about product appearance, peptide solutions can vary in appearance after reconstitution depending on several factors, including the type and pH of the reconstitution solution used, storage conditions, and handling. When quality concerns are reported, we take them seriously and investigate each case individually. As you mentioned, we replaced one of your vials because we believe in supporting our customers whenever reasonable concerns arise.

The CJC-1295 vials you received were produced through one of our U.S.-based laboratory partners that operates to compounding-quality manufacturing standards, and each production batch undergoes independent third-party analytical testing prior to release. We stand behind our quality control process and are always willing to review any product concern brought to our attention.

We would also like to clarify that, to the best of our knowledge, you have not been blocked on any of our social media platforms. We welcome customer questions, concerns, and constructive feedback. Our goal has always been to resolve issues professionally whenever possible.

As a small business rather than a large corporation or compounding pharmacy, response times can occasionally be longer than either we or our customers would like, particularly when investigating product-quality inquiries that require review. We respectfully ask customers to allow us a reasonable amount of time to thoroughly evaluate concerns so we can provide an accurate response rather than a rushed one.

We understand that you’ve chosen to work with a physician and obtain pharmacy-dispensed products, and we sincerely respect that decision. We encourage anyone seeking medications for personal use to do the same and to follow the guidance of their healthcare provider.

We appreciate your business and wish you the very best moving forward.

IF UR LOOKING FOR THE BEST, YOU’VE FOUND IT ON ALL LEVELS A+++++

I’ve ordered from ZenAminos since Aug 2025 and could not be happier. By far one of the BEST companies I have ever ordered from on all levels. Friendly, reliable, knowledgeable, respectful, trustworthy and above all, always has top quality products. They have super fast shipping & packages items with care. I have never and will never order from any other place. I am always referring others to Zen & always will! I cannot thank Chris and his team enough for all they do!

I find it disturbing you’re removing access to COA’s until AFTER an order has been placed!
I want to make my own decision on what to purchase after reviewing the COA!

If you’re concerned about pirates, you should put a watermark across your COA’s.
I find it hard to believe that I am the only one who feels this way.

Good morning Paula, Thanks for the review. Im not sure if you are referring to the email we sent yesterday or not to our customer base explaining regulatory changes in the space but I will assume that. Attached is the portion of the email you my want to read again.

We understand how important transparency and testing are to our customers.

To better protect our operations while maintaining that transparency, we are beginning to transition our Certificates of Analysis (COAs) off the website to a secure Google Drive system.

COAs will no longer be publicly displayed on the website
All batches will continue to be tested and tracked
COAs will be available via a secure Google Drive link

You will receive the secure Google Drive link after your order is completed. This will be included in your receipt email

During this transition, if a COA is not listed or you need immediate assistance, please reach out to our team at COA@ZenAminos.com and we will be happy to provide it promptly.

*Please note that COA@ZenAminos.com is strictly for COA assistance and is not monitored and utilized for customer service relations.

Inexpensive premium quality research materials

Everything I have gotten from Zen Aminos so far has been great, and most of the catalog is extremely affordable. They are always running surprise sales and promotions so it's really worth it to subscribe to their newsletter. Also, they have really worked to create a visible brand and aesthetic, which I like. Their branding and packaging is so excellent. I'm really happy to have found Zen Aminos!
