AAS can result in a decrease peak of plasma corticosterone concentrations by way of potentially disabling HSD-11B or 11B-HSD which are hosts of enzymes that catalyze the conversion of cortisone to active cortisol.. Almost inducing a state of adrenal fatigue by other methods of action, basically inducing adrenal fatigue like symptoms..You can experience this while on most AAS "especially" Trenbolone, drol and some pro-hormones (MT1/SD), there can be a slew of other rather aggressive sides not only from it's toxicity to the liver but through this other indirect course of action yielding a slew of undesired sides in "some" users....
I would suggest adding some DHEA with some sublingual vitamin B complex and take it from there.. Try and cut back on caffeine, in fact I would suggest extracting it from your daily life just for now..
An other suggestions, you may want to add some low to a moderate dose of GHRP-6 and/or Hexarelin, these peptide both act in a similar mechanisms and have been known to increase the release of ACTH which can improve the serum plasma levels with cortisol, restoring it to a health functional state, hindering any "halotestin or AAS" related sides that may be present by way of adrenal fatigue like symptoms..
Good luck..
