What's wrong with just using Cialis for performance, unless lack of libido is a problem? The latter can be helped by supplements that increase testosterone and DHT but doing that is not completely risk- or side-effect free.
Most methods of increasing testosterone have well documented unwanted side effects but tongkat ali does not work in the same way as, say, anabolic steroids. But your point is taken. Cialis merely lets you attain an erection it is not the same erection that would be obtained when taking a potent supplement like tongkat ali/eurycoma longifolia. Even if you do not have a libido "issue" it definitely increases arousal in such a way that enhances sex (at least for me). The topic was sexual enhancement. You can feel it mentally as well - almost like a subconcious projected confidence. Testosterone is the best aphrodisiac there is! I mean hell why not give it a try and see if it doesn't make you feel like you've been doing it with one eye open this whole time? I dare someone to point out a better sexual enhancement supplement that is better than tongkat ali. You won't I'd be willing to bet.
Well if we're talking about increasing testosterone, did you miss my posts about zinc right above yours?
Effectiveness isn't the only thing at issue here - safety is a real concern as well. In my mind, herbal supplements are inherently more dangerous because they can contain a large number of substances which can have any number of effects on the body. The net benefit of such a substance is going to be rather hard to deduce, especially considering herbal supplements have been prone to things like poor quality control and contamination with toxic substances.
My point is this: zinc is the most important mineral for the production of testosterone. If you're deficient in zinc, it makes by FAR the most sense to start supplementing there and to see if doing so increases testosterone. Zinc is also a very essential nutrient, so if you're deficient you should be considering correcting that deficiency anyway regardless if it increases testosterone or not. It's also an exceedingly safe supplement unless you're megadosing it and throwing your zinc-copper balance out of whack.
If that doesn't work, of course, or if you aren't deficient in zinc, then certainly you'll need to look somewhere else. I just get the feeling that too many people jump straight into the herbal stuff without considering *why* their testosterone might be low in the first place, and that leads them to make supplement choices that could be putting them at needless risk.
