How fast it came in! Wasn’t expecting to drop 4lbs in 4 days, wow. The YouTube videos about products is key 👌🏻 love the knowledge behind it and educating buyers.

Billy and Kenden were FANTASTIC!! I will definitely be reaching out to them next time I order! Billy helped me out with the spooky sales and Kenden helped me with some free product samples! Seamless and quick responses that contained good news only. 11/10
