Everyone is different, but in general, you want to keep some amount of test in the cycle. The softer look can come from a number of causes. One can be estrogen. Too much estrogen and you're likely to look softer. You can control estrogen through more AI or through less test. For most people, 2cc test cyp or Test e should be pretty controllable. If you still struggle, knock it down to 1cc. As for compounds to add to your cycle, primo would work ok, but the gains aren't going to be dramatic. Still, with the right diet, you could certainly make some progress on a test/primo cycle. If you want to keep the test low, something along the lines of this could work well
