Return of Effective Prohomones - A Breakthrough in Legal Supplementation

Remember when Prohormones worked as advertised without harsh side effects or dangers? Advanced Muscle Science (AMS) revives those days with the groundbreaking product 1-Androsterone! This product has many of the same beneficial effects that the now banned products 1-Androstendiol and 1-Test did. In fact, due to its unique legal formulation 1-Androsterone will give you even better results, because we have learned a few things since the original "andro" prohormones were on the market.

The most common benefits include the following:

- Non-Toxic (unlike virtually every "methyl" prohormone on the market)

- Orally Active Compound

- Extremely Potent

- Completely Non-Aromatizable to Estrogen

- Naturally Occurring

1-Androsterone converts at a high rate to 1-Testosterone and will give you similar strength and size increases to other products such as the old 1-Andro or 1-Test products that were on the market before they were banned. Old 1-Andro products were known for their high conversion rate and for being truly orally active. Those products also converted to 1-tesosterone (which is an isomer of testosterone) and were found in research to be 700% more anabolic (muscle building) than standard testosterone. Early user feedback reported lean mass and strength gains without much, if any, corresponding water gains. To sum it up, they have reduced estrogenic and increased androgenic activity. This allowed for increases in strength and aggression, reduction of body-fat and a leaner look to the physique.

Now, through a new and different legal formulation 1-Androsterone provides the similar results! Not a liver toxic methyl prohormone, 1-Androsterone combines the safest and most advanced delivery method available in a prohormone product to deliver better results than the older products. 1-Androsterone will improve upon what was an already high conversion rate to its target hormone, 1-Testosterone. Once again, like the older products, 1-Androsterone cannot convert to estrogen or DHT, so gyno and hair loss are not a concern.

If you are looking to relive the benefits of the older products with a safe and effective legal prohormone product, look to 1-Androsterone to provide the horsepower for your next cycle of six to eight weeks. It is best stacked with our other legal and effective superstar, 4-AD on cycle to keep up your libido and increase your gains. Finally, stack them both with Arom-X to boost your natural production off cycle and complete your AMS Hormone Regulation kit.


Your Next Generation Legal Prohormone

Before they were banned older products such as 4-Androstenediol and 1-Test were some of the most popular prohormones ever! These now banned products gave great gains in size and strength along with killer libido increases. Now, AMS has introduced a new legal formulation of a prohormone that will achieve similar results as the older products. Considered a wet prohormone, 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.

The original older products were effective prohormones to testosterone. Our new formulation 4-AD, 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.


Arom-X is the best off cycle legal estrogen management and natural testosterone production product on the market. This dual focus is highly desirable when combined with 1-Androsterone and 4-AD both during and after a cycle. Complete your hormone regulation kit with Arom-X. The proprietary formulation of ingredients in the amazing new product Arom-X include:

3a-Hydroxyetioallocholan Ethyl Ester

3a-Hydroxyetioallocholan Ethyl Ester is a brand new and magnificent anti-aromatase that is also a libido booster. Other benefits include an increase in focus as well as an increase in aggression. This is a perfect companion and balance to ATD.

1,4,6 etioallocholan-dione (ATD)

ATD is a powerful inhibitor of the aromatase enzyme, and as such, it reduces the production of estrogen in the body. In males, this results in a concomitant increase in testosterone production.

ATD can be used two ways. By itself to raise endogenous levels of testosterone production (most useful after discontinuation of suppressive hormonal products) and it can be used simultaneously with aromatizing steroids to minimize estrogenic side effects. ATD is extremely strong and it is overused in many other products (not Arom-X!), which can cause a rebound of the aromatase enzyme and a possible decrease in libido. While it is a very effective anti-estrogen compound, it is definitely a situation of "more is not better".

Beta Sitosterol

Beta-sitosterol has been shown to have activity in promoting prostate health. It also has cholesterol-lowering activity.

The unique combination and formulation of the legal and naturally occurring compounds in Arom-X make it the leader in today's marketplace
