Homebrew Chemistry Saturation Point question

What factors affect how saturated an oil can be with dissolved powder before it starts precipitating out of solution? Would it be beneficial to craft stronger doses of gear (400 mg/ml Test E vs. 200 mg/ml) in order to reduce pinning or injection volume in order to meet a more aggressive dosing regimen?

Apologies, I didn't see my previous thread, so I recreated it. Please ignore this.
