my take on your situation,,, i think instead of going over 1g of test just just now, add in others such as decca/equipoise/tren etc....
no need to make huge jumps, ride the wave along the way, you can make great gains without jumping in with 2 feet too soon
what i would do is 1g of test with 600mg of any of the above and maybe an oral, do that for 8 to 12 weeks...
have a week at 500mg of test, then go back on and switch compounds..
if you have the money start with the gh 4 to 6iu ed... ive yet to use inuslin so i cant advise you on that, it depends on the level of contest your going to do on how your going to approach this, i always think there has to be a risk vs benefit ratio
i wouldnt use it for a novice contest, definatly would as a heavy in the open class
