What natural supplements (not PEDs) are there reliable results of actually increasing testosterone levels?
I would like to know different opinions and experiences of supplements of this type, for example: tribulus, ashwagandha, zma ..
or supplements that are combinations of these or other...
Just wondering if anyone has come across a good "natural" alternative to pinning HCG. I've done web research and there's obviously tons of supplements that claim they work. Is there anything remotely as effective as the injectable?
