Max dose

Hey everyone, Do y'all know how I can avoid "hitting the roof" and not being able to get any effects for the next 2 days? What's the max dose/mg of mesembrine in a day to be able to feel anything the day after? Is something like 1g of Zen (7% alkaloids: 50% mesembrine, 25% mesembrenone, 25% delta-7-mesembrenone) and 250mg of TA15 (15% alkaloids: 80% mesembrine, 10% mesembrenone, 10% delta-7-mesembrenone) in 5ml of saline too much?
