Accurate Dosage of steroids for a pro bodybuilder

Pro bodybuilders should consume 3–5 grams of gear per week!

They take multiple substances since they all have slightly different effects or mechanisms, plus other substances like insulin, HGH, peptides, stimulants, and metabolic modulators.

• There is always a testosterone base, which for a beginner might be 300 mg/week, but for a professional, 1000–2000 mg/week.

• Other injectables are usually paired with the testosterone base, like nandrolone, trenbolone, and equipoise, in the 200–1000 mg/week range.

• Orals are added on top, like Stanozolol, Anavar, Dianabol, and Holstein, in the 10–100 mg/day/substance range.

• Moreover, HGH and insulin can add another 10% to your muscularity once you turn pro.

Naturally, when taking these high doses of steroids, it's also important to maintain healthy levels of prolactin and estrogen, which is why aromatase inhibitors like Arimidex or Aromasin are used.
What is essential is that DOUBLING THE DOSE WILL NOT DOUBLE THE EFFECTIVENESS but will only double the health side effects.
