I've had mild panic attacks off and on for years. Usually when I run things a bit higher. When I started TRT a few years ago I got them here and there. I even got them when I was natty. Being on test+primo at 200 and 100 I never got them. I began an experiment yesterday and swapped the primo for mast to see if I can get my e2 and lipids better. I injected my usual 100mg of test and 50mg of mast e yesterday mng a long w my usual hcg. Slept like a baby. Woke up this morning and was walking my kids to school and had the worst panic attacks of my f*cking life. Had clammy hands (first time that happened) and knots so bad I nearly fell over. I took a prescription Xanax that I have low dose. I have never used masteron before. Could this just be a short adjustment period or should I bin this sh*t? Any thoughts appreciated.
