Ret, yes primo is easy to make at 200mg/ml. It's methenolone enanthate, enth is a long ester. You can easily make 200mg/ml, or even 300mg/ml. Now if it were the version in primo tabs, methenolone acetate, yes that would be damn near impossible to get to 200mg/ml. If the test blend cepanon is like sust, then that's why it hurts, BA to dissolve the shorter esters in the blend. And lots of people get test flu, has nothing to do with the brand of test though.
