Kaizen 1-Adiol is no longer available

What is it?

1Adiol Up until now, most body builders were familiar with "Andro" prohormones (converting to Testosterone) and "Norandro" prohormones (converting to Nandrolone). Now, KAIZEN 1-ADIOL has been developed and is even better! KAIZEN 1-ADIOL is a precursor to testosterone, with no estrogen conversion. This well absorbed prohormone works on a different pathway than other prohormones, converting to 1-Testosterone (7 times as anabolic as testosterone). It is better absorbed than any other prohormone and is almost twice as strong as ANDRODIOL. Due to its chemical structure, KAIZEN 1-ADIOL cannot aromatize to estrogens. KAIZEN 1-ADIOL goes directly into absorbable testosterone, and consistent reports show increased lean muscle mass and strength.

Q: What do you mean specifically when you say that 1-ADIOL converts to a hormone that is over 7 times as anabolic as testosterone?

A: 1-ADIOL converts to an isomer of testosterone known as 1-testosterone. The anabolic potency of 1-testosterone and testosterone were determined (Counsel et al., Anabolic Agents. Derivatives of 5alpha-Androst-1-ene, J. Org. Chem., 27 (1962), 248-251) by the rat levator ani assay, which is the way that steroids have traditionally been tested for muscular anabolic activity.

In this study, testosterone was assigned a myotrophic potency of 26, while 1-tesosterone was given a myotrophic potency of 200. These potencies were determined by measuring the minimal doses from which significant increases in muscle weight were observed. It took over 7 times LESS 1-testosterone than testosterone to produce the same increases in muscle weight.

This means that it should take much less 1-AD to stimulate your muscles to grow than with a testosterone precursor like 4-androdiol (4-AD) - and this is without taking into consideration 1-ADIOL's oral bioavailabilty advantage over traditional prohormones.

Q: 1-ADIOL sounds good in that it doesn't convert to estrogen, but what about DHT? Is this going to have the same effects as Andro on my prostate?

A: While 1-testosterone can convert to DHT through an unusual pathway, the extent of that conversion is unknown. The extent of 1-tesotsterone's impact on the human prostate is unknown as well. According to assays on rats, prostate growth is similar to that with an equal dose of testosterone. But this is in castrate rats that have underdeveloped prostate glands to begin with. This kind of prostate growth (developmental growth) is in no way the same thing as benign prostate hypertrophy (BPH), the kind that can be damaging in humans.

Since BPH is estrogen dependent, there is a possibility that 1-ADIOL is in fact very prostate friendly. In case you do not know, DHT given by itself can actually reduce BPH because it reduces serum estrogen (US patent# 5,648,350, Dihydrotestosterone for use in androgenotherapy). The same may be true for 1-ADIOL — at this point we don't really know.

Q: Is 1-ADIOL outstanding for mass gains?

A: 1-ADIOL can put bodyweight on you, but if you compare the strength and pure muscle gains to the overall bodyweight increase it is less than what you would see associated with an aromatizing steroid like testosterone (for the same given amount of strength and pure muscle gains). This is because the mass gains seen with 1-ADIOL are not associated with water retention.

This is considered by many to be a very desirable property in an anabolic agent. It is for this reason that strong anabolic steroids such as Trenbolone, Halotestin, and Winstrol are so treasured for pre-contest usage. These steroids are not noted for promoting great body weight increases, but they increase pure muscle mass considerably and without definition-obscuring water.

Q: Would 1-ADIOL be a good product to use for losing fat or cutting up?

A: 1-ADIOL can be extremely useful for cutting up, and this is probably its most valuable use. While 1-ADIOL will not impart any direct fat burning effects like you would get from a thermogenic product, it can assist in losing fat indirectly. 1-ADIOL can minimize the loss of lean body mass (LBM) while dieting, aiding in the maintenance of a high basal metabolic rate.

While all prohormones can help maintain LBM, most of them also convert to estrogens. Estrogens promote fat gain and therefore their elevation is counterproductive while dieting. 1-ADIOL does not increase estrogen levels making it a superb prohormone choice for cutting-up.

Furthermore, since 1-ADIOL has little associated water retention, your muscle definition will not be adversely affected. You will maintain a lean, hard look to your physique.

Q: What about stacking 1-ADIOL with other types of prohormones? Is this advisable? Would this help mass gains??

A: Stacking 1-ADIOL with 4-Androstene-3, 17diol (Cyclodiol) or 19 Nor-4-Androstene-3 17diol (Norcyclodiol) prohormone products can be of value. You can get the mass gain benefits of the diol prohormones combined with the strength benefits of 1-ADIOL.

Q: Could you give some dosing and cycling info for 1-ADIOL?

A: The recommended dosage is one to three capsules (100-300mg) per day with meals. If three capsules are taken, then these should be spread out over the day (i.e. breakfast, lunch, and dinner). Subjects have taken more 1-ADIOL (600-900mg per day) and gotten excellent results with no adverse side effects, but the (conservatively labeled) bottle tells you to limit your intake to 300mg per day.

Q: Can women take 1-ADIOL?

A: 1-ADIOL is significantly androgenic, which means that it will put women at risk for virilizing effects much more so than a low virilizing product such as Norandrodiol. For that reason, it would probably be advisable for most women to avoid 1-ADIOL. Some women may be able to tolerate one capsule a day perhaps, but certainly for the majority of women it is just a better idea to take a Norandrodiol product.

Q: Is KAIZEN 1-ADIOL the same as Ergopharm 1-AD?

A: Yes, in that it is of the same chemical structure and quality.
