I love this product, I wasn't sure it was really helping me or not with my first bottle. BUT after my first bottle of Testocor was finished, within a week I with feeling tired, no energy, I didn't want to do anything, and weak. I Wasn't sure why I was feeling like this. Than I realized that It could be caused by not taking the Testocor! well I ordered the second bottle and it arrived in 2 days, I took 2 capsules immediately. Soon after it was in my system again, it was like a switch was turned on. I had my energy, stamina, and I couldn't wait to go to the gym that afternoon. I would recommend this product to any man that is seeking some of their youthful stamina and energy!
