Shutdown is shutdown. There is no such thing as "light" or "minor" shutdown, its all the same. How long you are shutdown matters, but that's determined by cycle length. Also how FAST you become shutdown should be considered. Tren shuts me down in days while test or dbol takes a couple weeks (2-3ish). I know this for my body from blood tests during cycle.
So the question of what shuts you down more is like asking what will get me to work? A sports car or Truck? They both will but one will get you there faster.
there are varying levels of htpa supression. if you want to really get at it, no one ever gets "shut down". only supressed. even 20 weeks of deca, the hpta is still functioning, albiet, very weakly.
example, 10mg of anavar is shown to cause supression on htpa function. I dont think anyone on this forum is going to run 10mg of var, and if they did, they sure wouldn't need to use a pct program.
all the sarms currently being research have some level of htpa supression.
how strongly an androgen binds with and interacts with the androgen receptor is going to be a determining factor in htpa supression.
11-keto-testosterone will not cause as much supression as testosterone.
superdrol vs a stacked product containing dimethazine and methyl stenbolone, can not really be compared.
ultimately, supression is going to be determined by dosage, and legnth of cycle.
the big thing to worry about is testicle desensitization, cause that's what is going to pump out your test. getting the boys back into full swing is whats key.
