Hello all, first of all I am glad to be a member of SST. Secondly, I was going to place my first order of GH with ParetoPharma but I am curious about the selection of GH. I was given a choice between Optitropin and OXYGEN HGH, both have same price per unit. I am relatively skinny and I want to pack some muscle size and possible increase bone width to expand my narrow chest. I also have natural low T and GH levels. Which one would you recommend for my purpose? Also, I have heard a lot about Saizen and Genotropin, but I failed to find a difference among all the GH types. Please shed some light from your shredded pecs and planetary delts on me.
