This Dylan "You son-of-a-bitch" Gemelli production hits on a critical element of s4 which is the dosing protocol. If you follow these guidelines it can be the difference between a positive and negative s4 cycle.
hopefully by providing the explanations in this video about s4 it will open up the door for more people to try because its too damn good to pass on... All the info that most have questions about is given in the video...
S4 is my favorite SARM by far, and those that are afraid to use it because of the vision sides are really missing out on a very powerful and effective SARM. This video is a must watch if you have been on the fence abut whether to try S4 or not
