Hey i've been using 1,4 for about a year now for sleep. Anyways, my source dried up and i just got gbl in the mail. How much pure gbl is equal to 1cc of pure 1,4? Thanks for your help
1,4 isn't comparable to GBL in my oppinion. If you want sleep just try starting with 2.5cc's to 3cc's of GBL. You can dose as you want. 1,4 is for the devil! stay away from it.
