What is the ideal stack for maximum strength and size when using steroids?
An ideal stack is an oral and injectable. The length of the cycle should not exceed 8 weeks. For example, a classic steroid stack in bodybuilding is Dianabol and Deca.
I've used Dianabol and injectable Primo but the best results I've had using an oral Winstrol and Sustanon 250. To me this is the ultimate stack! My cycle lasted only 4 weeks (being afraid about side effects, lol) but during those 4 weeks my physique added like 10lbs. Now, be advised that I did my first cycle after 20 years of bodybuilding experience and hitting a plateau and the medications were original, obtained from a pharmacy (there're lots of fakes out there).
The doses were less than moderate. Some users may describe my cycle as a "girly cycle", but I was concerned about potential side effects. You have to understand that the side effects are always dose-related. Nevertheless your natural testosterone production will be disrupted, so bear this in mind. The longer and heavier the cycle-the longer it takes to recover your test production.
In conclusion, if your goal is to build an aesthetic physique you don't need steroids and PED's. Just train hard, have a suitable diet and recovery and you'll experience results. If you're intending to compete that's a different story and a topic of another discussion.
I hope this information is helpful.
