im assuming they are both 10ml vials... need more specifics though... how many mg/ml is the test p and test cyp? no pun towards you, but it's really hard to give you answers without these type of specifics. a lot of places whether it's pharma grade or UGL (underground labs) will make different blends. also another question would be what was the dosage that you were thinking of doing per week? if this is your first cycle then i would prob recommend 400mg - 500mg per week just to get the effects of what its like to be on test. YES, pick up an anti estrogen (AI) like letro or anastrozole. a lot of people like letro, but i prefer anastrozole because letro is too strong for me (dry/achy joints, anxiety).
and correct me if im wrong man beast, but what i think manbeast meant is that test prop is usually injected everyday or every other day, the half life is really low so if your doing it every 4 days, your really not allowing the test prop to saturate in your blood, especially when test cyp is not gonna kick in til week 3.
many companies will make:
test prop 100mg/ml
test cyp 250mg/ml
now depending on how many mg you want to run per week of test and that the vial amount is the same as my example, im gonna take a guess at saying that you probably only have about 2-3 weeks worth of a cycle with just those two vials.
