DO NOT ORDER FROM COSMIC NOOTROPICS!!! I placed an order back in July for 3 products that were supposedly in stock. I was sent tracking information and waited patiently for my package to arrive, while checking the DHL website for updates. Well all tracking activity ceased the day after my order was placed interestingly. I contacted both DHL and Cosmic Nootropics after being told by both of them to contact each other. I was told by Cosmic to wait until August 7th. I relayed that info to DHL who said there was no need to wait and as the merchant, THEY, NOT ME, would need to contact DHL to open an investigation to find the lost package. I relayed that to Cosmic. They insured me they were sending a reshipment and I would receive it the middle of this week. Well, the end of the week has arrived and still nothing!! In fact, another order was “created, on August 7th, but it says “on hold!” There are over 20 email messages with this company. They have done nothing but stall. There is no delivery for me…there never was. I will be leaving reviews on sites suggested by ChatGPT. I’m disputing the charge and reporting them as one of the vendors as untrustworthy and with questionable business practices. Learn from my expert and save yourself the time and aggravation. Order from a vendor who stands behind their promises. You won’t find that with Cosmic Nootropics! Note: If you have had the same experience, leave reviews to let others know and dispute the charges to get your money back. Do not let them take advantage with these scams!

Hi Tammy! We’re truly sorry to hear about your experience and the frustration this has caused you. We always strive to provide reliable service, and we regret that this situation did not meet your expectations. Please know that we acted strictly within our Reshipment & Refund Policy, which is available on our website for transparency. In your case, we have already processed a refund for the order. Regarding the reshipment: we did create the replacement order, but since we did not receive confirmation from you that the shipping details were correct, it remained on hold. We understand how disappointing this must feel, and we’re sorry for the inconvenience caused along the way. Your feedback is very important to us, and we’ll use it to improve our processes so that situations like this are avoided in the future.
Always great customer service and reliable products.

I've tried many of their products and always had a fantastic experience, Semax, Phenotropil, Noopept and Vinpotropile and all of them works perfectly well and are a must try to any nootropics connoisseur!
