My husband started taking these Essential elements T-Hero Male Health Supplement - Muscle Builder & T-Booster with DIM, Ashwagandha, Shilajit, More - 60 Vegan Capsules about a month ago and he is in love! He said that, Approximately two weeks into taking the product he noticed an improved sense of wellness in his breathing and seemed more alive (if that makes any sense). He also said that his energy levels are higher than he has ever noticed before. At any rate, I love that the product is free of fillers and cheap ingredients found with so many so called natural supplements. Give it a try! I think you'll become a quick fan like my husband and I.
