Although chemically the only difference between testosterone and 1-testosterone is the position of the double bond, pharmacologically the two products are quite different. According to research done by the pharmaceutical giant G.D. Searle and published in the 1960s, 1-testosterone is over 7 times as myotrophic (anabolic) as testosterone(1). That makes 1-testosterone a phenomenally potent compound, surpassing even most synthetic anabolic steroids. No Aromatization
1-testosterone differs from testosterone in another way as well. Being a 5alpha-reduced androgen (a DHT derivative) it simply cannot aromatize to estrogens. The same goes for 1-AD itself -- no estrogen transformation can occur. This makes 1-AD unique compared to other prohormones -- all of which can either aromatize directly, convert to a product that aromatizes, or both. So what does this mean in the real world? It means that your chances of getting gynecomastia (bitch tits) from 1-AD is essentially zero, and that water retention side effects are vastly reduced compared to other prohormones.
The Only Truly "Orally Active" Prohormone Natural androgenic steroids are normally not very active orally. Large amounts have to be taken orally to see biological effects. This is because the first pass through the liver causes a massive deactivation of the compounds, primarily through the oxidation of the 17beta-hydroxyl to a 17-keto group. Chemists long ago found that by adding an alkyl (methyl or ethyl) chemical group to the alpha position of the 17 carbon, this oxidation can be prevented. However, this alkyl derivatization also greatly increases the liver toxicity. Therefore the usage of such synthetically altered compounds (methyltestosterone, oxymetholone, stanozolol) are not without substantial risk.
Luckily, there are other ways to render a steroid orally active, and do so without making the compound toxic to the liver. Certain structural modifications can alter the metabolism of steroids making them resistant to liver breakdown. One of these modifications is unsaturation (presence of a double bond) in the 1-position. One steroid that has this structural modification and is orally active is the anabolic steroid Methenolone, also known as Primobolan.
As you may have noticed, this double bond position that makes Primobolan orally active is the same one found in 1-AD, which, by the way, is also orally active. Steroids with this particular double bond characteristic are known as 1-dehydroandrostanes.
During the 60's and 70's some papers were published describing the phenomenon of oral activity seen with 1-dehydroandrostanes, including 1-testosterone and 1-AD. What was discovered was that these compounds resist metabolic deactivation by profoundly shifting what is known as the "17-keto redox potential" towards the formation of active 17beta-hydroxyl steroids(2,3). What does this mean? It means that when you take 1-AD, the liver serves primarily to activate the compound, rather than break it down and excrete it as it does with other prohormones and testosterone. It means that 1-AD is "orally active," yet it does not impart the liver toxicity that 17alpha-alkylation does. A Natural Hormone Made in the Body
One of the beautiful things about 1-AD is that in addition to its impressive pharmacological activity, it is also a natural androgen made in the human body(4) . This means that it is not foreign to your body, and that it can legally and openly be sold as a nutritional supplement. Furthermore, 1-AD's high rate of active conversion after oral administration is not just a "theory" of ErgoPharm's - it has been demonstrated and published in a highly reputable peer reviewed journal. Summary
Let's put it all together and see what 1-AD has to offer:
High oral activity Conversion to a hormone 700% more potent than testosterone Absolutely NO aromatization to estrogens Natural and safe
There can be no argument that this is the ultimate prohormone. Believe us, there simply are no natural compounds out there that can come close to what 1-AD does, so don't even bother looking. 1-AD is Now Available at FitnessONE.com
