My husband was diagnosed with way below the low end of what is an acceptable level of testosterone last year. He didn't have much energy, and was very frustrated because of it. The doctor put him on Androgel, (which is cheap at first, with the card the doctor gave him, to be able to get in less expensively than insurance, the first year, but even after he increased it to 50% more for him to use (and the cost of the prescription went up over a hundred dollars- and now it would be every 20 days he'd need it), he still wasn't feeling as he should- (and still not in the normal range of testosterone) though felt some better. I searched iHerb for some testosterone help and the reviews looked so good for this product- Ultra T-Male, so we got that for him. It really works. He went through one bottle, and started another- got his blood work done, went to the doctor and the doctor was thrilled that he finally was in the normal range. The doctor is glad for him that the Ultra T-Male is working for him, and didn't try to get him to use a prescription again!
