Great products, but limited in powders. Sometimes products are sold out given the tariff situation. I cannot ship from C I S countries meaning there’s less availability of products and slightly higher prices. Overall, I have been very satisfied with the website and the products offered. The one thing I would try to improve is offering products from the CIS zone through other countries to avoid tariffs. Also, it would be a great benefit if you sold dexamethasone Eye drops.

Hi Max! Thank you for sharing your thoughts with us! We’re happy to hear you’ve been satisfied overall. Ordering from our CIS warehouse is available for most countries, though in some cases customs restrictions may apply. However, we are trying to resume shipping from our CIS warehouse to the US as soon as possible. We really appreciate your feedback and continued support!

I really only stay coming back because I can continuously get Phenibut. But how come I can only get 3 packs at a time?
Response from CosmicNootropic· Jul 11, 2025
Hi Joshua! Thank you for your feedback. Unfortunately, due to regulations, we can only send three boxes per order.

Usually a really good experience with no issues. This time it took over a week to get my order processed due to cart issues that even support couldn't figure out. Eventually, I did. However, there were a few things in my cart that were in a really good special that ran out before the order finally was able to process. Very frustrating. Update: I'm going to change this to 4 stars from 3 because Cosmic took the time to reply to this post and send me an email. I'm sure next time will be a 5 starrerrr

I love the eye drops I get, Visomitin, they are the only drops that make my eyes not dry. The shipping is very expensive but seems to be getting better so I think they are working on it. I wish the free shipping limit was a little lower. Because the quality of the eye drops I use are so good and helpful it makes me confident to look into their other products, they seem to really care about quality.
Response from CosmicNootropic· Oct 3, 2024
Thank you for your thoughtful review! We're thrilled to hear that Visomitin eye drops are making such a positive difference for you. We appreciate your feedback about shipping costs and are continuously working to improve that experience. Some of our customers, who use a product regularly, tend to order several packages at once to stock up, this way the delivery is free, and you also get a quantity discount - it's a win-win :) If there’s anything else we can do to turn that 4-star rating into a 5-star experience, please let us know!
