I dont' know...
I think if u perpetually did 2 weekers with say 6 weeks rest in between each one...u will rogressively lower your hpta. I would say this would be true for the average person.
But to take test prop for a week, stop, no pct (and no other aas before or after)....u wud require very weak endocrine for that to happen.
I geuss u wud be in trouble b4 u eevn started.
