You could givea try. It doesn't contain nettle.
Here’s a little of the “techie” stuff about how it works:
positively alters 7 homeostatic mechanisms of action that effect free and total testosterone output:
Contains a natural suicide inhibitor of aromatase, and will improve the Testosterone : Estrogen (T:E) profile while concurrently increasing testosterone levels
Increases NO/cGMP levels, which leads to increases in lutenizing hormone (LH) and greater endogenous testosterone production.
Increases testicular (ALCAR) levels. High testicular ALCAR levels are conducive to heightened spermatogenesis.
Lowers levels of cytokines IL-6, IL-1, and TNF-alpha- cytokines, which inhibit endogenous testosterone production by reducing levels of LH.
Lowers cortisol levels and heightens Testosterone : Cortisol (T:C) ratio via competitive inhibition processes.
Increases cAMP levels, which also increase LH levels.
Influences/Increases androgen receptor (AR) binding via altering receptor electro-negativity.
After 8 weeks of usage of FREE TEST, test subjects were observed to have increased levels of free testosterone ranging from 50-200% over baseline. Impressive results for any product – especially one with no negative side effects!
Furthermore, the subjective feedback from the FREE TEST beta testers was nothing short of amazing. Within the first week users experienced feeling more motivated and assertive with shirt-splitting pumps, big-time strength increases, and revved up libido…all within the first week!
