i think for cyp it is 18 days till u start pct. get clomid and nolva from this site. you can

run nolva @ 20mg/ed and clomid @100mg/ed
(dosage for clomid could be different, do a search, 300/100/50 is another popular way to take it)

as far as cell tech or watever, it would not be a bad idea, but pct should be your main focus.
