Sounds like you're doing most things right. Are you eating enough? A calorie deficit will trash your recovery more than any supplement can undo. I've found that very gradually increasing my calorie intake over a long time seems to have increased my metabolic rate and energy levels. I now maintain my weight on around 3,000kCals per day (and I work from home on a PC).
Creatine monohydrate? Very few people can max that out with varied eating and it's one of the few supplements with tons of evidence supporting its efficacy.
If / when I have issues relating to low testosterone I'll probably begin injecting it!
