Some of the approved drugs are synthetic versions of the natural hormones, such as trenbolone acetate and zeranol. Just like the natural hormone implants, before FDA approved these drugs, FDA required information and/or toxicological testing in laboratory animals to determine safe levels in the animal products that we eat (edible tissues). Furthermore, FDA required that the manufacturers demonstrate that the amount of hormone left in each edible tissue after treatment is below the appropriate safe level. As described above, a safe level is a level which would be expected to have no harmful effect in humans.
First, my BIG question/concern is in making the whey. I first tried it with a 32 oz. tub of organic plain whole milk yogurt but didn’t get the 5 cups that the recipe said I should get. I used a linen towel the first time, then I used cheesecloth only to see actual yogurt going through the cheese cloth. How can I tell what’s the correct thickness of cheesecloth or towel to use?! And are we supposed to leave the yogurt or kefir out of the refrigerator when making the whey?? Doesn’t leaving yogurt/kefir out make it go bad??
