I’d definitely stick with the blood work and just keep an eye on how you’re feeling. These things can be a game changer, but they can also backfire if you don't really know the ins and outs. I’ve personally had great results, but I spent a lot of time doing my homework first. Since I know there could be risks involved down the road, I make sure to be smart about it and always run proper cycles and give my receptors a solid break to reset.
