4-AD-EC Information
The Premier Class-II Androgen
4-AD-EC Pro-Steroid Delivery System


4-AD-EC delivers optimal pro-steroid benefits over longer-term cycles up to eight weeks without the concern of side effects. So if you like being on more than you like being off, 4-AD-EC is the ultimate designer anabolic delivery system.

In fact, 4-AD-EC is so novel that we've filed a patent on the design. The EC (ethylcarbonate) part of the molecule, combined with our unique, liquid delivery system, provides nearly 100% efficiency of absorption and a 24-hour duration of action. No other pro-hormone or pro-steroid in the world can claim that, with the exception of Biotest's big gorilla, pro-steroid delivery system, MAG-10.


Designer Molecule Produces Results

To date, the only legal Class-II androgen we've found that meets our criteria maximal gains with minimum side effects is 4-androstenediol (4-AD).

Surprisingly enough, 4-AD is 95% as potent as Testosterone, and it turns out that it's a very important steroid in the body: Biotest research uncovered that there's actually more 4-AD in the blood than Testosterone, something that scientists had not generally been aware of. Since it's comparably potent to Testosterone, it has tremendous promise as a legal anabolic, but its effectiveness depends on actually getting enough into the body.

Early products, particularly capsules, weren't effective because so little of the compound reached the blood, and duration of action was short. These problems were largely solved with the introduction of Androsol Sports Skin Tonic. Using transdermal delivery, Androsol is able to achieve sustained super-physiologic blood levels of 4-AD (in the ballpark of 3000 ng/dL!) and to produce excellent muscle-building results.

A 5-lb gain in LBM within the first two weeks of use is common, given high protein intake, sufficient calories, and proficient training. Some users have even experienced a 10-lb LBM gain in two weeks!

While regular 4-AD in an effective formulation such as Androsol is very good for aiding muscle mass gains, it doesn't represent the optimum anabolic strategy. Androsol gave an excellent improvement, although the efficiency of absorption and duration of action still weren't high enough to achieve maximal results.

Fixing these problems with 4-AD was surprisingly simple. Biotest blueprinted a powerful one-step solution by adding a chemical structure called a protective group onto the 4-AD molecule. We didn't use just any protective group, either. We chose ethylcarbonate ester (EC) for the job. Reason being, it's by far the most efficient ester for accomplishing our goals:

EC won't break down in the digestive tract and it's far superior at increasing the absorption rate and extending the active life.

With 4-AD ethylcarbonate ester 4-AD-EC we were able to dramatically increase efficiency of absorption and duration of action. Combined with our patent liquid delivery system, we've achieved nearly 100% efficiency with more than 24 hours of active life from one single dose!

Bottom line, 4-AD-EC is the long-term user's dream come true. Now, for the first time ever, you can experience optimal gains and benefits that only androgens can deliver with minimal or no side effects and all this from one single dose per day.

It really doesn't get any better than that!
