A great one is bulk turmeric root. With the antioxidant properties being popular, the anecdotal evidence for helping gynecomastia and also supposed recovery properties, it would be a good pickup in my opinion. Many people are willing to try damn near anything to clear a bad case of gyno, but theres a lack of bulk turmeric around. Personally, I'm forced to buy about 5-7 bottles of Solaray brand, and even then the dosage is low.
