Hey don't mention it Man...you man, me wo..man :shh: but don't tell anyone :lol:
Beav before you start throwing your money at Test boosters ,there are a lot of ways you can increase T naturally. Obviously diet and exercise play the biggest roll, and this will hopefully increase insulin sensitivity overall. Which I know you already know.
Fat is very important in the diet for T, lots of good fats, not processed, cream, cheese, oils,coconut oil. Fatty bacon is great.
Also Cruciferous veg, Kale is fab, Bok Choy, broccoli ,Cauliflower,Brussels ,all these promote T.
Zinc is a aromatase inhibitor , I have been taking it for a bit now along with the B vitamins to enhance T ,to counteract high Progesterone which is a problem for me during my cycle. I have had promising results with it for my needs.
I would be honest and straight up front with everything you do concerning your Diabetes with your Dr, in the long run having good control and good overall health is the most important thing really. And chasing one medication with another to get a good aesthetic physique , would not be that wise in the bigger scheme of things...You will probably do yourself more damage than good in the long run and probably waste a whole load of money.
I don't know what diet you follow but I have found a low carb , higher fat, higher protein approach is the best for me as far as lean muscle mass to low body fat ratios are concerned.It's also the most beneficial I have found for my Diabetic control.
As you will know all about the diet already if you train as much as you do. Do you do cardio aswell? Maybe step this right up for a while to concentrate on getting body fat down and insulin sensitivity up.
Just a few ideas, sorry if it seems like I was preaching about the Test booster...but do you really need it???? And then to start wanting to buy Metformin ,it seems a bit extreme really.
There are other supplement that are good too, I'm sure the test booster you are on about is just natural supplements but they are expensive, and you can get them all naturally from foods. Or single cheaper supplements.
stay safe
