Timing for blood testing question

[JmAch]

I apologize as I am sure this has been posed many times, but I cannot find the resource- 1.=What is the optimal time to have labs done after pinning..... I do inj. on Monday a.m. and Thursday p.m. and plan to have blood draw on a Friday? 2. For PSA test, how long should one refrain from ejaculation as I hear this will affect numbers?
Any other recommendations for full panel blood testing- ie. fasting, sexual activity, supplements to "hold" etc that may skew results?
Thanks for your rec's!

Refrained for 48 hours before PSA test. Do labs on injection day before you inject. Since you usually fast before you do labs, Monday mornings seem to be the best.
