I don't care what anyone says, dbol is great. Many people feel great on it, but just as many feel lethargic. It has a bad rap for many reasons, water retention is a big one. I personally don't retain much water from dbol so I just get strength and size, some water but not much at all. I love it. Blue hearts are the only ones I want to use these days.
Liver toxicity is overrated. Yes it's harmful and will elevate enzymes, but when used responsibly in a healthy adult, it's not that bad. Elevated liver enzymes don't mean liver damage. In a healthy male they will return to normal upon cessation.
30-50mg a day is great when used in the beginning or middle of a cycle. It needs to be used with test. Drol has similar bad rep and a lot due to bloating yet I know guys who use it during pre comp cutting to keep muscle full.
Now the other reality is orals are really not needed. They are used for our egos just to get a quick boost and fast weight gain when starting a cycle. It won't to any more then a test/deca cycle will over the course of a cycle. Oils aren't liver toxic and will provide more realistic and sustainable gains for most people. But I don't see much water retention so it's not much different for me, the only issue for me, is I typically lose the strength and a few pounds of weight almost instantly after stopping use not matter what oils I'm on.
Dbol will elevate BP pretty fast and I do not like an elevated bp, so it has many negatives, most are overly hyped up on the Internet but for good reasons. Orals need to be used intelligently and in small amounts. With anything, moderation is key, support supplements should be used, ancillaries. There really aren't any supps that will protect the liver from orals but use them to help them return to normal.
Dbol is not a substitute to injectables, not a standalone, not a base of a cycle, and not to be used in teens, because they can cause serious problems but in a healthy adult male it's not anything you should fear as long as you have a brain, but keep in mind a test only cycle can provide the same thing without all the sides. Yes test has sides but is well tolerated at reasonable doses.
I can't say it enough times, after you have put some time in on the basics, experiment and see how AAS effect you, and which work the best for you. We all tolerate them differently but if you have on cycle blood work, which is cheap online, you don't have to guess at how it's effecting your body. Some people may see rapid spikes in liver enzymes from a standard dbol dose, while others may only get a slight elevation, but why guess, get labs and you will quickly learn if it's something worth using for you.
