Sublingual

Does anyone know anything about sublingual Testosterone Trocs, 100mg each. What would be the effective dosage amounts ? (ie 1/2 Troc (50 mg) daily or 1 Troc (100 mg) every other day). Just about everything I have heard regarding T replacement has been in the form of creams, Jells, Patches, or injectables. How good or effective is T in a sublingual form? Suppose a person having normal (low normal 375mg/dl) T levels were to use these Troc’s for mass gains what would be the optimum daily dosage to use and when should they use it. Lets say that the individual was a 41 year old male, worked out in the late afternoon or early evening doing a 4 day split ( 2 days on, 1 day off).
