An eight-ounce oyster has 18 grams of protein — making gains easy while upping your t-levels. Oysters are rich in zinc, a t-boosting mineral. From food, you get about 10 milligrams of zinc each day, but the body only absorbs 2-3 milligrams of it — putting you at risk for a deficiency. The common cold is actually a symptom of low zinc levels along with a low sex-drive, which is an indication of low-t levels. When low zinc levels are present, the pituitary gland limits the release of the luteinizing and follicle stimulating hormones; they are responsible for triggering T production in the testes. This then decrease the amount of androgen binding sites and free testosterone in the blood stream.
