I just changed my whole HRT routine from 5 gm Androgel daily to 200mg custom blended Sustanon once a week along with 250 IU HCG twice a week. I felt the change within the first 3 days, the 4th through 5th days were almost to the point of roid rage. I'm leveling off now emotionally. I suspect the initial spike pushed my T levels way above what the Androgel was doing. Last year about this time I did a cycle of 500 of Mexican Sustanon with QV 300 Deca a week and never had response like this one. Maybe it's the HCG....
