i have 3 10ml bottles of test e, that will = to 500mg per week for 15 weeks.

i was going to run 1-12 weeks but i will have some left over so its a waste.

options are

run the test weeks 1-15 at 500mg per week?

or run the test weeks 1-12. at 500mg per week and then week 13- untill it runs out at 100mg per week just to help keep gains?

i will still be doing pct from week 14-18 on both options.
