Get it, you won't regret it!
Size: 2 Fl Oz (Pack of 1)
This stuff is awesome. I've been battling a lot of sickness lately, and this stuff gives me energy and helps my immune system. The only downside is I'm still not sure how much to take. I'm up to 2 dropper fulls a day (I'm 250lb), but have no idea how much that really is.
Warning Tip: Any time you open the bottle up, do it over a plate or paper towel. This stuff tends to get EVERYWHERE, even if the dropper is in the cup, and it stains like crazy. So keep a spray bottle of rubbing alcohol near by if it gets on your counter, the sooner you spray it with alcohol and scrub it, the less likely it'll stain permanently.
But avoid doing this over white counters no matter how careful you are😅. I tried it over white counters once, and no matter how careful I was or how many paper towels I put down, tiny droplets still got in random places on the counter. I still got it out with rubbing alcohol.. eventually... but oh boy it was way harder to do, I had to scrub a TON. 🤣
