You have to remember one thing..........it will affect everyone differently like any compound. The generalizations you state that you are "supposed" to get, are just that, the "majority" get this or that.
I think one factor, although not necessarily against you, but will make you "feel" it differently is you are only 21, your natural levels of IGF and GH may be high, thus lessening the effects of exogenous introduction of substances/hormones like IGF.
Not everyone gets the acne or sore joints. Me, I am on day 22 and now up to 80mcgs split in 2 doses of 40 each. I have had ZERO joint problems, in fact my joints after 3 knee operations, dislocated L shoulder and numerous other 40 year old joint pains are GONE, hardly notice any joint problems at all since starting. My skin has improved to a more youthful appearance and my Hormone related breakouts have dissappeared.
I don't get the tired feeling "some" people report, would be nice since my second shot is after WO and just before my bedtime. This has not raised my appetite, but I most definitely have a higher protein intake. The fat loss was not real noticeable, more of a body composition changing, muscle dimensional change, just different, but something was positively changing. My weight has fluctated only a pound or two from 180 since the first day on, but the mirror has seen a DRAMATIC change in vasularity and lean mass.
MR is an awesome company and their product is Superior, it is all they do, so they do it well.
Hope this helps sort things out for you.
