On TRT, just do your own hypodermic shot. I hate, hate, hate, hate needles but it's easy to do. Ive never really gotten used to it but it is so easy to do. Just do it and get it over with. Gels and orals or pellets all have their own negatives. The needle is more of a mental block than an actual pain.
DHEA is great. I used it all the time before I went on TRT. DHEA is hormonal but not really anabolic but my energy levels, well being, etc... I read a study on DHEA being used in high doses , like 500 mgs a day, to treat depression.
At one point I was taking like 400 mgs a day and had no estrogenic side effects. I don't use DHEA now but I think I may use 50 mgs and see if it improves my mood. If estrogenic sides concern you you could use the otc AI (thats two words) arimistane like 25 mgs a day. You'll feel fan-fucking-tastic. Guaranteed.
