andro products are shit period, don't waste your time or money. If you want something that's not gear try Tribulus Terris it's an herbal that increases your natural test levels some..not a great deal either. So they too are IMO a waste of money but wont give you bitch tits.
If your a natty then food is your main deal more so than someone on gear. (Flame away all I'm saying is that it's the critical nature of diet comes more into play for a natty.)
6 to 8 small high protien meals a day with solid veggies.
There are only two OTC supps that I use that I think are worth a shit. Creatine and Gluatamine.
