Is it Primobolan Depot? If so the half life is in or around 14 days. That means it essentially tapers itself off.
I would wait on the Var. Basic science dictates you take one element at a time and document the results. So you would want to wait a bit and see how your body reacted overall to the Primo.
Once you are in the clear you could start Var and see how you react to that.
If you start right away it would blur the lines between the two and you would not know which was what.
Myself, I would wait a while. I tend to be conservative. Due to that I have an eye for my health. So I do the least amount necessary to achieve the desired results. I also like to see clearly how my body reacts to each substance.
Best of luck!
