Wow , that changes everything. I thought you have old school Test C in your hand sorry. I must say it will hurt like crazy if it containes what its on the label. Years ago, i used Denkall Test 400 with similar formula but less Test prop, i think it was only 25 mg but it hurt very very badly. 100 mg Test prop even sometimes hurts too much only by itself.
If you will use this Test 400 then , your plan can be like
0.5 ml 3 times per week. Total 600 mg per week.
