Considering your goals, I would suggest you dose as follows:
1) Leviathan Reloaded: Do full (recommended) dose.
2) RPM: Do half dose (2 capsules). The recommended dosage for your weight category would amount to 5 caps per day. Considering that Leviathan Reloaded and RPM both contain caffeine, dosing both fully would be an overdose of sorts. Two capsules of RPM should be fine.
3) Drive: I would recommend 4 capsules per day. Drive and Leviathan Reloaded both contain forskolin, so 4 capsules of Drive and the full recommended dose of Leviathan Reloaded should produce an appropriate amount of forskolin.
Aim to take 1 RPM, 2 Drive, and the first dose of Leviathan Reloaded first thing in the morning on an empty stomach. Wait about 45 or so minutes before breakfast.
The second dose should be the same about an hour or so before workout (also on an empty stomach). On non-workout days, take this in the afternoon on an empty stomach. Avoid taking this dose later than five or so hours before sleep, as the stimulants may interfere with your sleep.
You should see some decent fat loss and body recomposition, as well as improvements in strength, lean mass, and endurance.
