+1 on the dont do it. on one of my earlier cycles i got my deca in 3wks before i got my test. so i took 400mg of deca for those 3 wks.
wk1-everything was cool. pumped bout my cycle. no sexual side effects
wk2-no more morning wood. went from having sex 7x's a wk to 2 or 3. hard time keeping wood
wk3-no wood

!!!!!!
wk4-took 750mg test E(pumped bout cycle again and had effects of wk 2)
wk5-back to good
so moral of the story is unless your a priest dont use deca alone. it will fvck your juck up like a turned over tackle box.
seriously read the stickies on this board.
1st- go read the test and deca profiles in the profile forum.
2nd-come back to this forum and read the stickies.
3rd-go to the PCT forum and read those stickes.
then order all your pct supplies and whatever else you plan on using.
start cycle when you feel comfortable with your knowledge and when you have ALL ITEMS OF THE CYCLE!!!!!!!!!!
that is enough to get you started and get a basic understanding of steroid use. ive prolly read all those stickies 4 or 5 times.
