Look into different ways to stimulate GABA and/or supplement with oxytocin. There might be a sponsor here who might carry oxytocin?
Without getting to technical and over-the-top explanations. Both of these natural occurring neurotransmitter/neuropeptide act in an orchestrating way to inhibit excitatory responses (on other overactive neurotransmitters). As for endogenous oxytocin, some individuals genetically have an abundance of this neuropeptide to where others don't express but minute amounts. Not to mention, as we age, we lose the the ole muscle regenerative, love neuropeptide. According to some literature, oxytocin levels seem to rise with the use of Tren. With that said, as aforementioned, aging and genetic predisposition to either high or low endogenous oxytocin levels may explain why some individuals experience higher levels of anxiety when using Tren. This goes without saying, repeated blunted actions (extended AAS use or other environmental factors) on our hypothalamus may be partially to blame, as well. That's all speculation on my behalf, though it makes quite logical sense.
Nevertheless.
There's a laundry list of different Rx/supplements and certain foods (to a lesser degree) that help tame the beast within for supplying the raw materials for GABA. Some individuals, including myself that help put the breaks on anxiety while on Tren have been low doses of hCG (on paper has shown to help stimulate testicular 17-hydroxyprogesterone--> Allopregnanolone-->GABA). Some individuals can get by using a low dose of pregnanolone at night, in which can exert benzo reactions. Again, there's several different methods one can pursue to help feed the raw materials to stimulate GABA, i.e., glutamine, apigenin, Kava, ect.
In the end, it comes down to your biochemistry and how your body metabolizes different types of supplements.
Ultimately what has/may work for me, may not effectively work for you.
It may be a simple manipulation of your dosing protocol of your AAS?
Good luck.
