I have placed several orders now. I have had an issue before where an order was cancelled after I made the payment on their end because it ran out of time(it was over the weekend). I reached out to them via their phone number on the website. Got a real person that answered the phone in under 2 minutes. Explained the problem and they apologized for the inconvenience, confirmed the payment and processed the order. Overall good experience with Swiss Chems. As far as effectiveness of the products. My research rat has been observed to respond to the compounds in a manner consistent with what those compounds are intended to do. Based on the results witnessed in my rat, I have been able determine that the products are legitimate and in fact what they say they are. In conclusion, read their terms of service and the instructions given at checkout and you will have no problems getting what you pay for.
