For beginners, it is recommended to start with a dose of 10-20 mg per day for 4-6 weeks. The drug is really effective for rapid muscle mass gain, as it increases protein synthesis and retains nitrogen in the muscles. In just a couple of weeks, you will notice an increase in strength and volume. But keep in mind that DIANABOL Spectrum Pharma on MisterOlympia shop has a short half-life, about 3-6 hours, so it must be taken several times a day to maintain blood levels. There may also be side effects such as water retention, acne and possible liver problems. Therefore, I recommend using it in combination with supporting drugs and be sure to undergo recovery therapy after the course.
