With new oils that are available and different solvents that a re used now so ba and bb don't have to be used you can easily make test 350-400 mg that will stay stable and can be completly painless if done correctly I have been cycling for ten years now and products have came long ways. I used t-400 when it would cripple you for a week and just used again in my last cycle a month ago and the newt-400 from denkall is completly painless and tested at 350mg I was shooting 2cc of the 400 with 1cc of parobolin in glutes and shoulders and was completly painless which totally shocked me
