First dose - any advice?

[Sympho]

Next week i'm taking mdma with two friends of mine at a party.
I bought 100mg of a good MDMA, my friends have already tested it :D So i'm sure not to get PMA or shit. Is 100mg ok or should i lower the dosage? I'm 171cm and i weight 53 kg.
Oh, i have crystals, in my city there isn't a good disponibility of pills..(I live in an island..) Well, should I do something the days before to prepare me for the drop?
Sorry if I'm asking silly questions, i'm really excited and i don't want to waste my mdma.. You know, here is very difficult to get good mdma!
EDIT: Also, how should I dose it? Maybe 50mg first and then 50mg later?

If it were me, id drop 100 mg right from the start

I'd just drop the 100MG that will be a good first dose for sure

Remember TUMS to neutralise the acid in your stomach. I just got some today and I can't wait to try them - some people say 1 pill = 1.5pills if you neutralise the acid.

if you are 100% sure it is what it is drop the 100mg in one go...splitting it 50/50 will be a waste and you will not get the full effects.

you got rabbits on your island?

100mg is perfect for a first timer ! Have a nice time
