I'm just planing on taking the hit on the muscle loss - if it gives me benefit for my PFS, like CD said, I have the rest of my life to build muscle. I think the HIIT will surprise you, at first I thought it would make me weaker but I FEEL GREAT after finishing them and hitting an ice cold shower. I take nothing but cold showers now too, the benefits of those are amazing. Takes a lot of willpower to make it a habit, but that's the kinda willpower building you need to follow through with something like this.

Also, I took the Polyrhachis Ant Extract today with coffee, and other than the fact that I put literal ants in my mouth and took them, they really gave me a jolt.
