I honestly don't have anything bad to say about this besides the cost but i also feel the cost is important to the placebo, spending money on this makes me want to work out harder, so essentially I'm spending money on a placebo but research also shows the affects persists even if you know its a placebo so here i am. But after reading some of these of reviews on this page there's no way these are all legit, like zero chance. so here is genuine advice, if you have the extra money to spend on this why not go for it it wont hurt (probably) and maybe it'll help, but it you don't then please do not waste your money on this, none of this matters, just work out eat healthy it'll be fine. I am a legit pharmacist with a doctorate and the supplement industry is an unregulated scam show, so as I said before. the placebo is real, so if you purchase this as i have, you have to accept that most likely you guy purchasing the placebo affect and that's fine with me. the more invasive the intervention the stronger the placebo, a pill is better than powder, injection is better then pill, you get the idea. Just please be responsible with your money, I like this greg dude hes got some sauce I'm okay with supporting this, but again, if you think this is going to change you life and the money back guarantees make you feel safe, dont buy this, this is nothing special, go on science direct and search it up.
