Ok, I'll save you the "you're too young" speech....
Why are you running testosterone propionate for 8 weeks? If you're looking to use it as a kickstart to your testosterone cypionate, that's fine, but you'd only have to run it long enough until the testosterone cypionate kicked in (4-6 weeks tops).... but you have Dianabol - methandrostenolone - as a kickstart. I'd save the testosterone propionate for another cycle and bump up the testosterone cypionate a bit....also, 8-10 weeks is long enough IMO... simpler cycle and it should give you some nice gains. For P C T, run the H C G for 10 days (500 iu ED) during the last week of your cycle... then a week or so after your last test shot, start the Nolvaldex - tamoxifen citrate - and run it for a minimum of 4 weeks.
