I've been on TRT for 3 months now and even though my T level is near top of the reference range, I have not experienced faster recovery from workouts or an increase in muscle strength or endurance. What's been bothering me the most is severe DOMS. It is worse than before TRT. Apart from TRT, the only things I have changed is taking a multi vitamin/mineral supplement (Enzymedica Enzyme Nutrition Men's multi) daily and drinking home made milk kefir daily. Could any of these things be contributing to my severe DOMS? Is there anything that can be done to reduce DOMS?
How often are you squatting / deadlifting? The older you get, the less elastic muscle fibers are, and thus the longer the recovery time between strength training days.
Also, are you getting enough protein in your diet?
Personally, and there are some studies to back this up, I have found that a daily Vitamin E supplement, Magnesium supplement, and beet powder supplement helps with both exercise performance and recovery. That said, there is some evidence that while Vitamin E can reduce muscle and joint soreness, high doses of antioxidants can have a minor impact on gains.
