"19-Nor 3-Andro Integrates 3 Potent Precursor Substrates That Enhance Testosterone and Nortestosterone Production to Help You Build Lean Muscle Fast!"

It’s no secret that finding ways to increase testosterone levels is the current direction the performance enhancing trend is heading. And why not? - testosterone builds muscle! It’s a fact! The more circulating “free” testosterone you have in your system the more lean muscle mass you’re going to gain! It's as simple as that.

In the Journal of Applied Physiology, scientists concluded . . .

19-Nor 3-Andro . . . what it is and how it works -

19-Nor 3-Andro is unlike any other hormone precursor on the market. By uniquely integrating 3 precursor substrates, 19-Nor 3-Andro provides a potent hormonal punch. Each of the pro-hormones is a single enzyme reaction away from conversion to the potent muscle building hormones testosterone and nortestosterone.

100 Milligrams of 19-Norandrostenedione

Each capsule contains 100 milligrams of 19-Norandrostenedione. 19-Norandrostenedione is a unique anabolic substrate that coverts to an androgen called nortestosterone. This is an efficient one-step enzyme conversion process.

Nortestosterone is a distinctive androgen that has a higher anabolic/androgenic ratio than testosterone. Though not as potent as testosterone it adds a unique dimension to androgen onset muscle growth. You see, nortestosterone binds differently to the muscle cell's androgen receptor. It is theorized that the receptor affinity for nortestosterone is very high thus binding the molecule "tighter". This may make nortestosterone more efficient in delivering it's "anabolic" signal.

100 Milligrams of Androstenedione

Androstenedione is a potent androgen produced primarily in the adrenal gland. Androstenedione has been shown to support “free” (the non-bound biologically active) testosterone production through a single enzymatic reaction in the liver.

100 Milligrams 5-Androstenediol

5-Androstenediol is another unique androgen substrate that has been shown to support testosterone production. It is believed to be as much as 3 times the potency of androstenedione in its conversion into testosterone. What sets it apart however, is that it utilizes a different conversion enzyme than either androstenedione or 19-norandrostenedione. This may allow for efficient conversion without overly taxing the enzyme pathways.

You get multiple conversions via different substrate pathways.

5-Androstenediol also has a unique characteristic not found in other pro-hormone substrates including 4-Androstenediol. It exerts anabolic (muscle building) properties in its unconverted form. This means that it may promote muscle growth even if it's not converted into testosterone. This appears to unique to 5-Androstenediol.

Lastly, 5-Androstenediol has been shown to have immunostimulating effects.

Testosterone is Derived From ONLY Two Metabolites

Testosterone is manufactured in your body from only two metabolites - Androstenedione and Androstenediol. Nothing else in the body converts directly into testosterone. By providing both Androstenedione and Androstenediol you are delivering the very two androgen substrates that will naturally convert into muscle-building testosterone.

Take on capsule before bed.

Train in the afternoon.

Take one capsule immediately upon wakening.
Take one capsule at lunch time. (optional)
Take one capsule 30 minutes to one hour before you train.

Train twice daily.

Take one capsule 30 minutes to one hour before your morning workout.
Take one capsule at lunch time.
Take one capsule 30 minutes to one hour before your evening workout.

Beware of "Fake" 19-Norandrostenedione!

19-Norandrostenedione is a very expensive compound. Because of this you have some companies cutting corners. Unfortunately there are many bogus products on the market claiming to contain 19-Norandrostenedione. We have tested numerous brands and have found widespread fraud and label short comings. Two widely distributed and deceptively respectable brands claiming to contain 19-Norandrostenedione as an ingredient actually had NO detectable levels of the pro-hormone.

AST Sports Science guarantees all our products to be 100% pure HPLC tested and certified. For guaranteed purity and potency insist on AST Sports Science supplements.

Ingredients:
100 milligrams Androstenedione
100 Milligrams Androstenediol
100 Milligrams 19-Norandrostenedione

Size:
60 capsules

Strength:
300 milligrams per capsule

Dosage:
1 capsule two to three times daily

Not for use by children, teenagers, pregnant or nursing women. Do not use this product if you have breast, uterine, ovarian or prostate problems. If you are under medical supervision, consult with your physician before taking product. Teenage boys already produce plenty of testosterone so pro-hormones are of little value. Too much testosterone at this age could cause premature closure of the growth plates which control the growth of the body's long bones. This could stunt their growth. Do not take pro-hormones until you have reached your full growth potential. Cycling Recommendations: We recommend that you take two weeks off for every four weeks of taking pro-hormones to prevent your body from adjusting to the exogenous (external) source of hormones. As always, consult your physician before taking any product that may alter hormone levels.

U.S. Federal Trade Commission WARNING: This product contains steroid hormones that may cause breast enlargement, testicle shrinkage, and infertility in males, and increased facial and body hair, voice deepening, and clitoral enlargement in females. Higher doses may increase these risks. If you are at risk for prostate or breast cancer you should not use this product.
