Excess weight suppresses testosterone production, so it is great that you are working out as well as losing weight. Talk to your doctor about clomiphene (now generic but original brand was Clomid). Unlike injectable or topical testosterone, oral clomiphene stimulates the production of your own testosterone, doesn't shrink your balls (actually increases their size) and is designed to kick start your testes so you will no longer need anything to maintain a healthy T-level. The drug was originally used to increase fertility in women, but its mechanism works in a similar way in men. Repros Therapeutics has trials underway for using the drug specifically in overweight men and the clinical trials show very good response. It is expected to clear FDA approval in the near future. But, until then, many doctors are prescribing the (cheap) generic off-label. I've written about it elsewhere in this forum (it worked wonders for me). Full disclosure - I now have invested money into Repros' stock.
