I think that TRT will return men to the level of acne they had in there 20's. But these severe problems are not something that I have any idea about. These problems are more often reported by body builders, power lifters etc that take high amounts of anabolic steroids. You might find some useful info on the steroid forum, even if its disappointing.
This will have specific information:
When starting TRT, some pores that were blocked will need to clear with eruptions. My acne cleared up after a while; which might be a normal course of events for most.
