4-AD will give you some serious mass gains when stacked with our other new legal product 1-Androsterone. Used alone, it will still give you solid, steady gains that you will be able to keep for years.4-AD is Our new formulation that is naturally found in several tissues of the body. 4-AD is converted to testosterone via the naturally occurring enzyme 3beta-HSD. 4-AD converts to testosterone at a significantly higher rate than other previously available prohormones (such as androstenedione), and like the now banned older products also does not have the weakness of conversion to estrogen and/or DHT prior to conversion to testosterone. These factors made the older products some of the best testosterone prohormones on the market at their time. Like our other new product 1-Androsterone, 4-AD also converts at a high rate to testosterone. We have licensed these advanced delivery system legal formulations for utilizing your naturally occurring hormones to provide the most advanced system on the market today for blocking negative side effects while increasing free testosterone! Again, like the older products 4-AD does not directly convert to estrogen or DHT, and you can use the product the same as you used the older products such as 4-Androstenediol and 1-Test.4-AD is also more androgenic, meaning it has more male characteristic enhancing properties. This is of course, something all males desire. When stacked with 1-Androsterone, you can expect extraordinary mass and strength gains while experiencing increased libido enhancement and the energy to power through the most grueling workouts.4-AD Supplement Facts: Serving Size 1 capsule Servings Per Container 60 Amount Per Serving % Daily Value Piperine 2 mg Stinging Nettle (Leaf) 10 mg 4-Androstene-3b-ol, 17-one 200 mg Enhancement Complex 3 mg Stinging Nettle 100 mg 1,4,6 etioallocholan-dione 5 mg percent Daily Values are based on a 2,000 calorie diet.Ingredients: Other Ingredients: Pyrolsate, Gelatin, Magnesium Stearate, Silica.Directions: As a dietary supplement, take 1to 3 capsules per day in divided doses with food.
