Are natural thyroid stimulants such as those containing guggulsterones worth a damn? When I cut again for summer, I am thinking about cutting with diet alone for a few weeks and then doing 2 3 week or so cycles of clen and one of these. I don't really want to run T3(cytomel) because I don't want to get into anabolics that I would need to block muscle loss from the T3 for another year, possibly longer. This is just me planning WELL ahead of time with a plan. Any thoughts?
