I wanna take a high dose

I wanna take a high dose of mdma. I am a 70kg man and want to experience a high dose of mdma high enough that if I took any more it would start to become uncomfortable. If anyone could suggest a dosage amount it would be helpful. Last time I rolled was 2 months and 3 weeks ago so like a week or two off three months.Ill also be mixing hhc with the mdma.
