We all have those guys in the gym that talk about how they love to do dbol only cycles. Here's why that is not a smart choice:
Don't do a DBOL ONLY cycle! EVER!
There are plenty of good reasons for this - Obviously in that Dianabol is a 17-alpha alkylated steroid, warranting short-term use. Since Dianabol has little Androgen receptor activity, it functions particularly synergistic with compounds that have a strong Androgen receptor activity as is the case for all the aforementioned. In other words - stack it! Forgetting about the science here - do you want to make muscle, strength and water gains and end up feeling pumped and huge by the end of your cycle only to realize that the dianabol mainly gained you water and a few weeks after the cycle you lose it all?
Dianabol is a methylated compound with a certain toxicity, so in the interest of safety you wouldn't use it longer than 6 weeks on end, 8 weeks at the absolute maximum and only under supervision of a medical professional who can monitor your liver values. Arnold was said to use it for eight weeks at a time (of course this is only speculation), but even if this was the case, Arnold was on a whole other level than most beginners. Don't copy what he did and expect the same results - his workouts, nutrition program and steroid stacks were designed for his body and his genetics - never copy him or anybody else for that matter. Dianabol heavily aromatizes so its not particularly useful during cutting and with 6-8 weeks of use maximum, that leaves the option open - Stack it with another, injectable, compound that can be used for longer terms (beginning of stack when other compound is least active).
Dianabol is mainly meant to kick start your cycle gains. This is normally done by stacking it with a longer acting product, such as testosterone enanthate or cypionate, deca or equipose. For best use, include it early in a stack.
Weeks 1-4: Dianabol - 20-25 mg daily.
This should be more than sufficient for a beginner and just fine to kickstart your mass gains. Sometimes less is more! When it comes to 17-alpha alkylated drugs, this is one of those times. Liver health is something that you should be very important to you.
When stacking with a longer-acting product, such as testosterone enanthate or cypionate, Deca or Equipoise, the best use is early on in the stack. Dianabol is a very fast-acting steroid and most injectables don't start showing their real value for 2-3 weeks. That makes it particularly useful to kick off a cycle with.
