Good product and fast service
By Aaron W.
I know you've been doing it for awhile... but your prices are a bit ridiculous. Your taking advantage of "Dumb Bro" mentality and charging that much just because they'll pay it. I took 15 capsules out from Anogenin. I weighed and measured the volume of each and there is a standard 15% difference between all. How can people get serious about the science of their stacks if your not serious about giving a solid consistent product?

The preworkout is extremely intense and the fat burners seem to be doing their job very well also. The only thing that was discouraging was the delay in the product being delivered through USPS. They quoted the delivery on 2/2/23 and then again on 2/3/23 and the product didn’t get delivered until late afternoon on 2/4/23.

We're so happy you like the products! Unfortunately, Once the product leaves our warehouse there is nothing we can do about transit times or delays caused by the postal service. To accommodate postal delays, our economy shipping option is 7-14 Business Days. While USPS's estimates may have been inaccurate, Your item arrived in five business days
Fast delivery service better then other supplement companies in Florida. Only thing I didn’t like was the bottle of supplements came in a plastic bag but that’s not going to stop me from shopping more.

I’ve only been using Arson for a few days now so I can’t speak about fat loss yet but man is the energy insane!!! I take 1 capsule in the morning on an empty stomach and it keeps me going all day. No need for coffee and energy drinks anymore. It has also helped surprise my appetite
