Well in talking to you, you already know where I stand with it. Rather enjoying it at the moment. No pct, but in cruise. However I wish I had had it at the ready to start right when I came off blast. Or even a couple weeks prior. Instead of 6 weeks later!!
Will it be the same as your AAS cycle? No
Will it add in some great benefits (recovery, strength, fullness, sleep)? Absolutely
I think if you start it ASAP, even before your pct begins, it will help prevent losing as much size and shape once pct begins.
Just get your mind right. Be prepared for the reality of coming off. I know your cycle has been a real game-changer. Take whatever gains, or maintain of gains you can get, and enjoy the ride.
