Sorry just reread your thread. So you put 2.5 cc of primo 4 times??Seems that's gives you more the 500mg or I misinterpreting something?I always ran 200 mg of test with 500 mg of primo. It works out to in a slin pin injected daily, 0.82 cc. Bearing in mind 250 test and 100 primo
I just use an empty vial put 5 cc of primo and .8 cc of test in it twice and shake before drawing to backload the slin pins. ( truthfully I put 2.5 cc of primo in 4 times and 1.6 c cof test in it once. I only have 3 cc barrels)
I call it primotestin, lol. I write it with a black marker on the outside.
