Hey man, to be honest save you time and money they simply don’t work, you can do it all that with diet and hard training. Those 2 things will ensure your T levels will be as optimal as they can for your body. There’s no cookie cutter one size fits all number but to get your levels as optimal or upper end of normal diet is the one. Meat, sufficient sodium intake, getting the minerals for foods like veg fruit and eggs plus slamming the weights to illicit the bodies need to release hormones and then the biggest one enough sleep and rest. Money better spent on the food my friend just my 2cents hate to see you getting taken by a business 👍🏻
