I always say herbal Test Boosters will increase Total T by a couple/few hundred points, the higher you are normally, the smaller the increase. This *can* benefit (saying nothing of Placebo in the first place): Well Being, Libido, and Fat Loss. I say all this, because this is exactly what has been shown in some properly conducted studies. So if that is what a person is after, because they can't/don't want to get on TRT - and they don't mind paying out the a$$ for a lifetime supply of an OTC supplement - by all means, have at it.
But they will not take you from 800 to over 1500, and they will not add more lean mass to your frame, and they will not increase your 1 RM - because there are properly conducted studies showing that bouncing around the physiological range means nothing in that regard.
I know you know this - I just wanted to get my take out there in this thread because despite what most people will say in public, deep down they believe that any increase *at all* in Free/Total T = more muscle/weight lifted. It doesn't - unless it's Placebo
