I will assume you are looking for something to raise test levels, in order to increase nitrogen retention, and gain strength/mass correct?

If that is the case, then look into Activate Xtreme by Designer suppliments. IMO its the only "test booster" out there that will help with strength/mass gains.

If your just looking for a libido boost, then I would go with a regular tribulus product, or something with long jack, and maybe some maca. Fuze by Primaforce is pretty good for that.
