SL (sub-lingual, meaning under your tongue)- This involves mixing up the same kind of Hcg that is used for injections, but taking a larger dose twice a day, 12 hrs apart. You put the fluid under your tongue and have to hold it there for at least 5'. Many suggest you then don't eat or drink for another 15'. This is a good method for people who don't want to do the shots, but you do have to remember to take those doses roughly 12 hrs apart. The standard dose has been 166 iu's, 2x/day. However the newer research shows there may be benefit in taking a higher dose, 250 iu's 2x.day. With this method you have extra cost for the Hcg, but you don't have to buy sterile vials or syringes. This method also uses pharmacy-grade Hcg.
