With supplementation (3 squirts per day of Androgel), about 800+ ng/dl. I could raise it to 4 squirts and still be within normal guidelines but I am happy where I am. I was way under 200 ng/dl without Androgel and felt very tired. Does the Androgel contribute to what success I have had with lifting? No question about it. You cannot build muscle without T. However, in my demented old mind, I justify it by saying that as long as I stay within medically accepted normal T levels, I can consider myself natural or, to put it another way, I do not abuse AAS. I also have to take synthroid and do not consider myself not to be a natural lifter because of that either. Scripts are relatively easy to obtain in the US if you have low T. The benefits of male hormone supplementation as a means to increase one's on-going quality of life has become widely touted and accepted in the medical community during the past decade. After insurance, the cost to me is less than US$2 per month. If you do not have low T, then you do not medically need it although I am sure it is available on the black market as are all sorts of AAS that are even much more potent. I could get T in an injectable form but I have heard many stories of peaks and valleys since it is normally injected two to four times per month. I also take 1 mg of Finasteride daily to help avoid the conversion to DHT which can contribute to hair loss. One anecdotal side note is that I have noticed that the more bald men become as they age, the less likely they are to need T supplementation. I assume that is due to higher T levels which means higher conversion to DHT. There may be some studies out there that agree or disagree what I seem to have noticed but I have not come across any yet.
