Zinc doesn't inhibit aromatase but is used in the production of testosterone. Supplementing it will help your body recover as it will be easier for it to produce test. You don't need
ZMA or anything that costs over 10 dollars. Go buy a regular ass zinc supp and magnesium supp and take them before bed.
Also there is no need to take 4g - that is way too much and can lead to zinc toxicity. Which you don't want. Just take one tablet of each at night. I use the 'nature's promise' brand or whatever it is.
