Hey guys, this might be a stupid question, but I would rather be curious than ignore it. Anyways, I was taking my SARMs (specifically S-4 and MK-2866). I noticed at the bottom of the SARMs are a crystal/rock like substance. I'm wondering if that's normal? Also, should I stir or shake the SARMs before I take them to try and mix up the substance? Thanks to all who help. Sorry if this is a dumb question!
