I am planning my next cycle:
16 weeks
4ml sust or cyp pw for 12 weeks (week 1 - 12)
A gram per wk??
1ml prop eod for 4 weeks (week 13 - 16)
I like this but you only need to do it for two wks to pick up the long ester 
1mg arimadex ed (week 1 - 18)
Too much bro. .25mg to begin then titrate up from there if necessary.
optional 50mg dbol ed for 6 weeks (week 1 - 6) (milk thistle if used)
I like.
optional 2ml deca pw for 12 (week 1 - 12)
Dont need it.
pct
start 3 days after last shot of prop
hcg 3 shots pw for 2 weeks (week 17 - 18)
hCG on cycle @ 250iu 2/wk
nolvadex 40mg ed for two weeks (week 17 - 18)
noladex 20mg ed for two weeks (week 19 - 20 )
Add clomid here 75/50/50/50
and then start again a few days after pct...
Start what? Another cycle?? *Time on plus PCT = time off.
What are your thoughts on this cycle plan?
Could I use test boosters like HCGenerate or something during PCT and if so when to start?
No.
I have been considering using proviron instead of arimadex or alongside it?
Not necessary.
Sperm production and general health are always a concern and any advice is much appreciated...
You better run hCG on cycle if this is important to you.
I am considering HGH in maybe a few cycles time..
.Never used it.
