my T shots, testosterone cypionate
, is prescribed for my low T state. IF you can get your husband in to a doctor, see if the can get a full hormone panel, while he may not have Low T, he might have other problems. I take it once a week and when i do, WOW, its like the sun is shining on me! Yes, its hard to build mass with low T, and the general energy level is down and depression is a side effect.
If he does have low T, then shots may or may not be needed.
