Testosterone Troc

I have heard of many different applications of T replacement (ie… creams, jell, injectables) but I haven’t heard anything about sublinguals or also known as Troc’s. Has anyone had any experience with them? They are kind of like geletine and rated at 100mg each. I was told that when perscribed the usual dosage would be 50mg daily or 100mg every other day. 1. What would be the best daily dosage to use for building mass? 2. When would be the best time to use them?
