IMO even 14 days for Test E/C is too short of a time, the ester is still in your system @ 500mg for 12 weeks and PCT calculator should be used.
Agreed. The PCT calculator suggested waiting 22 days minimum (for a test e, 12week cycle @ 500mg/week, via two 250mg injections). There's a "Show FAQ" link on the PCT calculator page that explains what you just mentioned. Pretty cool stuff in my opinion.
