Abstract: Provided herein are compositions (e.g., pharmaceutical compositions) comprising deuterated testosterone, deuterated methyltestosterone, deuterated androstenedione, or derivatives thereof. The provided compositions and related methods may be useful for treating and/or preventing various diseases and conditions, such as hypogonadism, delay of growth and puberty, weight loss associated with HIV-associated wasting, vulvar dystrophies, micropenis, breast cancer, and sexual disorders.

Abstract: Provided herein are compositions (e.g., pharmaceutical compositions, nutraceutical compositions, foods, beverages, cosmetic compositions, diet supplements) comprising deuterated caffeine. The provided compositions may be useful for treating and/or preventing various diseases and conditions, such as obesity, causing weight loss, increasing metabolic rate, reducing appetite, increasing energy expenditure, increasing urine output, increasing sodium excretion, reducing edema, a pain disorder, apnea, hypotension, an encephalopathy, a neurological or psychiatric disorder, and an inflammatory disorder.

Abstract: Provided herein are compositions (e.g., pharmaceutical compositions, nutraceutical compositions, foods, beverages, cosmetic compositions, diet supplements) comprising deuterated paraxanthine. The provided compositions may be useful for treating and/or preventing various diseases and conditions, such as obesity, causing weight loss, increasing metabolic rate, reducing appetite, increasing energy expenditure, increasing urine output, increasing sodium excretion, reducing edema, a pain disorder, apnea, hypotension, an encephalopathy, a neurological or psychiatric disorder, and an inflammatory disorder.

Abstract: The present disclosure provides compositions comprising deuterated forms of acetaminophen. When administered to human subjects, such compositions form less of the toxic metabolite NAPQI, and therefore are useful in methods of treating various diseases and conditions with a reduced risk of liver injury or other side effects associated with non-deuterated forms of acetaminophen.
