Some steroids affect ALL receptors, while some only affect ONE type of receptor, while others have very little effect on ANY of these receptors.
Steroids that cause an OVERSATURATION(too many receptors activated) of these various hormone receptors, WILL CAUSE SHUTDOWN.
Steroids that DO NOT CAUSE an OVERSATURATION of ANY of these various hormone receptors, will NOT cause SHUTDOWN!
The Following drugs either DIRECTLY or INDIRECTLY activate ESTROGEN receptors, to varying degrees:
Testosterone
Methandrostenolone
Mathandriol
Oxymetholone
Nandrolone
Boldenone
The Following drugs either DIRECTLY or INDIRECTLY activate PROGESTERONE receptors, to varying degrees:
Nandrolone
Trenbolone
Oxymetholone
The Following drugs activate Androgen receptors, to varying degrees:
Testosterone
Methandrostenolone
Mathandriol
Oxymetholone
Nandrolone
Boldenone
Trenbolone
Halotestin
Oxandrolone
Stanzolol
Chlorodehydromethltestosterone
Methyltestosterone
Methenolone...
(ALL AAS*)
As we can see, the steroids that cause HPTA SHUTDOWN either OVERSATURATE ONE SPECIFIC receptor, or they activate too many TOTAL receptors(Androgen/Estrogen/Progesterone)
For instance, Trenbolone causes HPTA SHUTDOWN because it OVERSATURATES BOTH, the ANDROGEN and the PROGESTERONE receptors.
Testosterone causes SHUTDOWN because it converts to ESTROGEN and DHT, therefore, it oversaturates the Androgen/Estrogen receptors.
As we can ALSO SEE, the steroids that DO NOT cause SHUTDOWN of the HPTA, do NOT oversaturate ANY of the different hormone receptors, and thus, do NOT cause SHUTDOWN.
Methenolone(Primobolan) does not possess ANY Estrogenic or Progestational ACTIVITY WHATSOEVER. It does, by virtue of being an anabolic steroid, posses a SMALL Androgenic component. Because it lacks ANY ESTROGENIC/PROGESTATIONAL component, and it lacks a strong Androgenic component, it WILL NOT CAUSE SHUTDOWN!
Oxandrolone(Anavar) posseses NO Estrogenic/Progestational component either. AND, it also lacks a strong androgenic component. Thus, Anavar will NOT cause shutdown.
