You can add primo. Overall though, I would want to see your doses a little higher than this to get a good anabolic effect. Understand that test at a replacement dose will help to keep your sexual function normal and support growth at a normal speed, just like any other human with average test levels. We don't need to ramp up to crazy doses to get a solid effect but we do want to get to a supra level in your blood in order to make cycling worth while. So for starters, I would bring the test up. If you want to still keep it on the low side, just go to 200mg. This is still going to be in the realm of replacement. Then add to that your primo at 300. This would be enough to see a decent difference while keeping your cycle still quite moderate. You can do this for 8 wks minimum. You may take it to 16 wks. From that time, I would then go back down to your replacement dose and give yourself at least 8 wks off before doing labs to ensure you’ve returned to normal health before considering a cycle again. While you are on this cycle, you will find that you’ll convert this higher level of test to more estrogen. Most people will be fine but it would still be a good idea to have an Ai on hand. You could use arom at 12.5mg 2x wk to start. Splitting your shots into 2x wk and taking the arom the day after your shot. If you find you need more arom, increase to a 3rd day on one of your non shot days
