Horny goat weed and Yohimbe if you want herbs..
Viagra is an option...
Testosterone issue... maybe go low dose androgel if you are low? they make 2.5g packets.. deliver 2.5mg's of test if I'm not mistaken..
Yohimbe?! What, did you just step out of a time portal from 1991?
Look, if you want to raise test naturally, UNLEASHED is the only sane alternative since it lowers SHBG, which in turn raises free testosterone.
If youwant to lower estrogen without the carcenogenic effects, again, do it naturally. POST CYCLE and ALpha Sustain work very well -- obviously, not as strong as a-dex or aromasan, but it'll help keep levels more stable, drug free.
But if you need weekly injections because you're clinically low and too old to recoup, then that's what you need. There is no other option. You can use the supps along with it, but only as an adjunct.
Viagra does not increase testosterone or elevate libido.
