is there any product (natural herb; prohormone,etc.) that can truly raise your test levels besides actual aas test?
also if it (a product) does raise your test levels can actually keep them up without raising the levels for a hour or two and then your back down to your normal test levels?
Low dose clomid, 10 to 20mg 3 times per week ensure optimal levels of testosterone. There are many scientific studies to back clomids effectiveness in raising testosterone. The low dose means no mental or physical side effects.
Or did you mean legal non prescription products?
Lowering your body fat levels will raise testosterone levels. The "aromatase enzyme" which converts testosterone into estrogen is largely produced by body fat. So lowering body fat is a natural "aromatase inhibitor".
Aromatase inhibitors such as 6-0x0 are shown to increase testosterone via lowering estrogen which fools your bodies hormone regulation system into producing more testosterone in order to maintain balance.
In any individual there is an inverse relationship between body fat % and testosterone. With the exception that extreme low bodyfat like exhibited by bodybuilders is supressive of testosterone production due to inadequate calories and overall increase stress.
There is a scientific study I read which showed that an obese person given the aromatase inhibitor arimidex caused their testosterone to shoot up from low to normal. His testosterone was being lowerd by his bodyfat which was causing excessive amounts of estrogen production.
