HPTA Suppression



Is there such a thing as a "more or less suppressive" steroid ? I read that Deca for example is extremely HPTA suppressive while Primo is way less suppressive... I thought all steroids are 100% suppressive even used at very low doses. For example even with a low dosage of Primo you won't be producing any testosterone of your own, none, zip. Could someone clear that out for me please ? Thanks :slight_smile:
