it isn't a competition to seeing how high you can get your test levels. you can be perfectly fine with a 400 test level and some other dude on testosterone with a 2500 level can have loads of problems
That's a really good idea. Get blood work done before using the product and then get blood work done again once you have been using the product 2-3 weeks.
A good natural testosterone booster should increase free and total testosterone levels by around 20%
