Also, get more cyp and run 750mg/week if you've done a couple of prohormone(steroid) cycles, especially w/ superdrol. You might be disappointed if you dont. The 500mg of test will feel like nothing compared to your old SD cycle(s), though the sides are less and overall it is better/more effective in the long run. At least think about frontloading with 1g the first week if you cant do that, it always seems to make my cycles more productive (and attains peak blood levels of test concentrations faster). IME, when on test only cycles I always start to notice increased pumps and libido, weight gain/strength around the 4th/5th week, just like the first week or two of an oral feels like. Nothing magical, except the feeling stays as long as you're on the stuff, unlike orals that fizzle out after 3 or 4 weeks (i.e. SD/PP).
There are many ways to do it, you could also wait it out the first few weeks and add the orals to the end. Or you could use prop, suspension or TNE for the first few weeks/last few weeks in a similar fashion.
I'll tell you what, you've made the right choice to go with injectables. They are so much healthier, don't wreak havoc on your lipids or liver like some orals, and the gains are better/more maintainable, and the neg sides are fewer. The pain (which is very little) of sticking a needle into your body is well-worth avoiding the negative sides of orals that can, in some cases, damage your health.
Good luck.
