See my Clen recipe in the kitchen chemist cookbook sticky

I think it would be easier to make Clen and t3 like a oral suspension then capping it because the doses are so low ,to make t3 100mcg what a nightmare

Oral suspensions are the ONLY way to go to get and accurate dosing consistantly. The variation in dosing in caps would be to great and with those compounds could actually be dangerous.
Dougoefre5h's mother/child system works well to create and accurate mix, as well as for storing the majority of the mix before transfering to a child for use.
