• Acquire Hard, Dry & Striated Lean Muscle Mass
• Easy to Stack with other Prohormones for Maximum Gains
• Helps Increase Strength for Mass Building Cycle

DecaBolin® is orally active, extremely powerful and rounds out Hi-Tech's Pro Anabolic line, offering the only legal “Nandrolone” precursor on the market. DecaBolin® converts at a high rate to its target hormone Nandrolone and is better than testosterone for building mass and strength as it produces fewer side effects. It's effectiveness at the androgen receptor of muscle tissue is superior to that of testosterone.
Nandrolone (“Deca”) is prized as the perfect anabolic compound. DecaBolin® — 19-NorAndrost-4-ene-3b-ol, 17-one Decanoate — is the only product of its kind still legal to convert to “Deca” in the body. Even more important is that DecaBolin® cannot directly aromatize to estrogen nor does convert to DHT or its derivatives, making it highly potent, completely non-aromatizable to estrogen and naturally occurring.

THE SCIENCE

Early user feedback reports lean mass and strength gains without any corresponding water gains. This allows for increases in strength and aggression, reduction of body-fat and a leaner look to the physique. It is a really good stacking product because it has so many positive benefits. Some athletes use DecaBolin® alone or stack it with 1-Andro products (1-AD®), 4-Andro (Androdiol®) and Superdrol® to experience the most potent pro anabolic compounds on the sports supplement market today.
DecaBolin® is extremely popular with bodybuilders and weightlifters due to its ability to add muscle mass and strength while maintaining leanness. 19-NorAndrost-4-ene-3b-ol, 17-one Decanoate  is a new compound that's a two step precursor to 19nortestosterone. This conversion takes place in the body as 19-NorAndrost-4-ene-3b-ol, 17-one Decanoate  --> 19norandrostenediol --> 19norTestosterone. This new compound is comprised of lipophilic ester (Decanoate ester bond) at the 3-key position to not only to increase the stability of the compound, but also to increase purity. The term "19nor" means that a methyl group was removed from testosterone at a key position on its molecular backbone. This slight alteration of the chemical structure reduces the DHT related side effects (prostate issues, balding, acne) as well as the estrogenic side effects (gyno) that testosterone possesses. Because of its relatively low side-effect profile and its overall effectiveness, 19-NorAndrost-4-ene-3b-ol, 17-one Decanoate  has rapidly become the prohormone of choice for competitive trainers looking to enhance overall lean muscle mass.
This Nandrolone precursor is quick to attach itself to natural steroid receptors in the body. It is further believed that Nandrolone's effects last longer than even testosterone. The real benefit of this amazing Nandrolone precursor, however, may be that while it produces good anabolic effects in the body, its aromatization to estrogen and its negative androgenic side-effects are significantly lower than that of testosterone and older testosterone precursors like Androstenedione and Androstenediol.
This combination of anabolic properties with reduced estrogen aromitization and androgenic complications is precisely what makes DecaBolin® such an effective, potent, and relatively safe muscle-building supplement. One important side-note here is that drug tested athletes need to be aware that because of its conversion in the liver to Nandrolone, DecaBolin® may indeed lead to positive on a steroid test for Deca Durabolin or Nandrolone.

So now you might be asking what in the world is 19nor? The 19-nor prohormones are a group of compounds that are precursors to Nandrolone. The chemical structure of the 19-nors differs from the more familiar and naturally prevalent Androstenes and Testosterone by the absence of the number 19 carbon atom and its attached hydrogen atoms. The removal of this chemical group results in a much flatter three-dimensional structure. That structural change in turn results in much more favorable binding affinities for skeletal muscle rather than for prostate and other sexual tissues. This is important because a high binding affinity means that a substance is more likely to enter the cell and bring about the desired effects.
Nandrolone (also known as 19-nortestosterone), the substance into which the 19-nors are to some extent converted by the liver, has a binding affinity that is not only high for skeletal muscle, but that is roughly equal for skeletal muscle and sexual tissues such as the prostate. In comparison, testosterone has a binding affinity as much as 50 times greater for sexual tissues (thus its greater "androgenicity") than for muscle. So, Nandrolone has anabolic effects (which take place in muscle) but less androgenic effects (which occur in sexual tissues). One of the most talked about benefits is the ability of 19N or prohormones to ease joint discomfort due to heavy lifting. 19-NorAndrost-4-ene-3b-ol, 17-one is a molecule derived from Nortestosterone. It converts to Nandrolone when assimilated into the body through absorption. Nandrolone acts as an anabolic composite which apportioned its nutrients helps to create a leaner body mass and uses up stored fat more efficiently. This in turn provides rapid recovery mechanism to exhausted muscle mass. 19-NorAndrost-4-ene-3b-ol does not aromatize or synthesize to estrogen when taken and was noted as being able to improve the individuals mood, as well as quick recoveries during workouts. 19-NorAndrost-4-ene-3b-ol can aid in the increase or enlargement of the muscle. Its nutrients also repair and rebuild muscle between workouts, and some athletes enjoy an increase in energy.
