In my opinion you must run it as long as you can afford for. I am using for more then 6 months already and my strategy is to keep running it for as long as possible. I have bought a lot of the stuff, so I have a supply for 6 more months
So far I am using 25mg/day but I might increase it up to 50mg/day. The longer you use it the better benefits you get, just like with all of the growth hormone peptides, and synthetic growth hormone.
My recovery on this stuff is awesome, to be honest I've experienced better recovery from workouts only on steroids. My strength has increased, sleep is also incredible and skin also improved. I really advice this stuff to everyone who is looking for additional advantage in the gym, doesn't matter if on or off steroid cycle.
