I followed the winning products noted by Good Housekeeping study as I wanted products verified by actual scientific studies.

I was torn between three and four stars, but I like it to buy more and enter into a regular delivery program for awhile, sums it up. I tested with the classic "low T"--I haven't retested yet, so I don't know if this product has had a measurable impact on my testosterone level--but, I have felt more energetic then in months. My weightlifting has improved, with seemingly greater strength, and I think I have noticed a firmer musculature. I have been on Ageless Male for a month and a half. But the changes are significant enough to have me continue use.
