Hey guys i am about to embark on my first cycle and have done plenty of info. Since it is my first one i am going with strictly test c. @ 500 mg a week split up monday and thursday. I know i should have an Aromatase inhibitor (AI) on hand in case of gyno symptoms but they are pretty pricey @ $300 for 28 tabs. Is there a product a a vitamin shop that i can use as an alternative ?
