DBOL was always one of my favorites since it was inexpensive and you got great gains almost immediately. Fantastic for strength. Watch out for wicked increases in blood pressure that can come on very suddenly. Monitor it and if you get obvious symptoms (e.g nosebleeds) stop immediately. 4 or 5 tablets a day translates to 20-25 mg each day - a pretty conservative dose. I would advise noy using it for more than about 3 or 4 weeks - usually just to amp up thethe cycle before the test kicks in. Good luck.
