While athletes and some researchers believe that testosterone produces a mass improvement in performance and endurance, others believe that it cannot produce overnight effects. It cannot give a jolt of energy to sportspersons in order to improve their performance, since testosterone acts over time to build muscle and strength in the athlete. But even then, there has to be a considerable amount of effort (in terms of exercise) on the part of the athlete. Simply taking testosterone without any exercise or a suitable diet will only do more harm than good.
The partition coefficient of the ester in question is important because is effects how long the drug itself stays in the system. If the testosterone transfers too quickly from the oil to the blood, the result is a sudden spike in testosterone which then rapidly drops once the dose has been used up. In the example of free testosterone injected into the muscle from a water suspension (as in Aquiviron, mentioned above), the testosterone is essentially immediately available to the bloodstream due to its low partition coefficient, and thus there is an immediate spike of testosterone which is used up quickly in the body.
The common dose for Dianabol is 30-50mg each day , with a cycle that would usually last between 4 and 6 weeks . 30-40mg would be an effective dose for a person that is new to Dianabol, resulting in great gains in muscle mass and strength, whilst restricting possible side effects. More experience users may wish to take a slightly higher dosage, although like most other compounds, there is a dosage level where the muscle and strength gains plateau off and the side effects heighten, resulting in a point in which it is not worth increasing the dosage. Most experienced users will rarely take a dosage over 70-80mg per day.
