How long after change before new blood work?

Went from 100 mg of Test-Cyp and 12.5 mg DHEA two times a week and started a trial blast. My original Test is pharmacy grade and I have my lab work from before and then 8 weeks in. Now I started 75 mg of Test Cyp and 30 mg of Tren-Ace every other day, but these are UGL supplied so I want to go have my blood test done to see where the numbers are and verify that I am actually boosting levels for some gains. How long after changing the cycle should I wait before having testosterone levels checked?

Cypionate takes about 5 weeks to fully saturate.
Levels will slowly taper up from first shot and peak at week 4-5. You'll definitely feel the strength gains at week 4 and being able to add poundages(assuming you're in a surplus and proper programming).

As far as acetate ,itll peak even faster.
Problem is if this is your first , you shouldn't be using another compound besides test to see how you react mentally and blood work wise.
Especially with something like Tren. Thats my personal opinion. To each his own .
