Should you take it just to raise the test levels? - Definitely no.
Do more research. It is much more complicated that just that, and there will always be consequences that you will have to deal with. HCGenerate ES would be a good starting point if you just want to raise the testosterone levels a bit in a safe manner, as it will not suppress your natural testosterone production, and it is all natural without any side effects at all. In fact, it is a supplement you can take for very long periods of time without any problems at all.
