Personally I always add some Ammo or TUTH in the mix, mainly because of the androstenone in those products. Ramps up sexual attraction a fair bit for me.
If you’re buff your natural testosterone levels are already quite high, and so will be your androstenone output. So you might not need it. I myself hit the gym every now and then, but I’m definitely not very muscular. Think I need the extra androstenone boost.
