For those who’ve run multiple bulk phases, how do you think about total weekly mg relative to food and training?

If someone has calories, protein, and training intensity fully locked in, is staying around ~500 mg/week total (e.g. Testosterone + another compound) limiting progress?

Or does the diminishing returns curve still apply regardless:
• Big response up to ~500 mg
• Slower returns beyond that
• Increasing side effects at higher totals

At what point does increasing total mg actually translate into noticeably better growth during a bulk? I am doing a bulk with a friend and he is pushing 1200 a week and making great progress. I would say that I am making progress, but not at his pace.

I was listening to a podcast with Todd Lee and John Jewett where they referenced Broderick Chavez and mentioned a guideline of around 15–20 mg per pound for PED dosing. I’m assuming this would mainly apply to higher-level or professional bodybuilders, not the average lifter. Curious how people here interpret that—does that seem like a “top-end” framework, or something more broadly applicable?

(I also realize that this subject might have been beat to death over the years).
