i dont think at this point there is any ideal approach to taking gh , some favour 3 x big doses a week some pw, some twice a day some 5 on 2 off some 2 on 2 off.
there are many things to consider, gh is a costly en devour ,i would rather be on gh longer at a reduced dosage than shorter on a higher dosage as i believe with gh duration of use is what makes it sparkle.
if you can afford the 5iu ed over a longish period go for it then again 5 on 2 off is also fine i have run it both ways, start low, 2 iu ed and build from there .i would rather run gh 5 on 2 off over 6 months than 5 iu ed over 3 months
with reagrds twice a day logistics come into play, carrying a round a pre loaded slin pin that needs to be kept cool is a pain or impractical for most . i opted for 5iu ed one shot at 4am and it worked great for me in the long run.
