As we all know, injctables are generally healthier than orals, but many orals are not very bad for you at all when run at low to moderate dosages. In addition, many orals can be run at low to moderate dosages pretty much indefinitely without liver enzymes becoming excessively elevated. As one poster said, as long as bloodwork stays within range...or doesn't become too elevated, you can continue to use them basically forever. Now, the doses most people use today will not allow them to run orals for long periods of time without experiencing unacceptable bloodwork, but many guys would be surprised to learn just how much the body can reasonably handle without exoeriencing serious side effects.
In general, D-bol could be run at 15-20 mg/day for YEARS and YEARS without liver enzymes becoming seriously elevated....and when you get guys using good liver support products, dbol at 15-20 mg/day will barely cause any flucuation in liver enzymes, allowing the individual to continue using that dose indefinitely. I know one guy who ran D-bol for close to a year ay 60-70 mg/day and his liver enzymes were elevated but not into a dangerous range. The doctor wasn't overly concerned. He went off a short time after and his liver enzumes returned to baseline within a few weeks. I know another guy, a previous world champion powerlifter in the 165 lbs class, who used 10 mg of D-bol every day for 5 years and his bloodwork was perfect. He would take 10 mg every morning like clockwork. His base cycle was low-moderate dose test & Deca (with 10 mg d-bol), which he used all the time...and right before a contest he would add in 50 mg Anadrol/day and 100 mg tren/week...yes, only 100 mg of tren per week. That was only for about about 6 weeks, 3 or so times per year. He is in his later 40's now and in in perfect health. This is because he never pushed things to the limit...and this man busted his ass in the gym. I am sure he decision to use relatively small amounts of gear was due to the fact that he wanted to stay within the 165 lbs weight class and would already have to drop 20 full pounds in order to make weight, so he couldn't afford to gain any more weight at all.
Still, the point is that d-bol is relatively mild and when used at low doses and can be used for many years without issue. There are some medications that are considerably more liver toxic than a 20 mg dose of D-bol...and some of these medications need to be used every day for life. These patinets are regularly monitored by their doctors and live long, normal lives.
So, if you want to use 40 mg of D-bol for a few more weeks, go for it.
Note: The liver is not what most guys need to worry about when using orals, it is the cardiovascular system. It is more important to keep cardiovascular health markers in range than anything else.
