I was in the market for a new supplier as the last one had gone dark. The product quality had also slipped. There is always a concern when it comes finding a new supplier as reviews and companies can be a little risky at first. Sadly not everyone out there is honest and many rip you off. After some hunting, I gave these guys ago, started off with a small order with some new labs Id not tried. Found the products and the site to be fantastic. Easy methods of payment that suits me. Always fast to respond to my emails and happy to answer any questions I have. There isn't a single bad word to say. As for SIS, I've found them equally reliable regardless of what other reviews might say here and there. The thing to remember is diet and training is key if those are right no matter what gear you're on it won't work for you. Cant fault them.
