I was told that it takes 2weeks for the enanthate to kick in, I take 2 shots of 250mgs a week... Its been 5days and two shots and I swear I can start to feel it, my muscles are getting harder and my muscle injury in my calve that i've had for 3months has mysterioulsy started feeling 90% better, and I am feeling a little water retention. Is it possible for it to start taking effect sooner for some people? Or maybe my mind is playing tricks on me!ha. Also is there any difference between taking 2 shots @250mg or 1 shot @500mg if so which is better?
