hcg mixing

[TM248]

i've been reading about hcg a lot and am deciding whether or not to use it...

my cycle looks like this

1-4 dbol 20mg/day
1-10 test E 250mg/week
12-14/15 clomid 50mg/day

this is my first cycle and some say that hcg is not necessary but if i were to use it at the end of the cycle maybe weeks 10 and 11 what dosage and do you need to mix it with water or is that just a comfort thing??

thanks
TM
