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. 🤣

Effective for me!
Size: 2 Fl Oz (Pack of 1)
Thank you God!
The first day I took it I felt it.. I was having issue with my left eye optic neuritis/ optic pallor and I felt it working on my eye. It literally felt like it was restoring my eye. My eye was no longer irritating me and after around 2 months I was able to wear my contacts again…
I like this one better because it has other supplements like magnesium and lions man mushroom which I know can help possibly aid in cell regeneration…
The other one I tried is too concentrated for me and has a more harsh taste… this taste is way more tolerable…. I will continue to buy this one… it’s the best one… for me at least❣️ Thank you!

It was ok
Size: 2 Fl Oz (Pack of 1)
It tastes better than all the alternatives I’ve tried, but it makes me wonder if it is more sugar and less potency because I didn’t feel a noticeable difference after taking it like I had with some other brands. It also is a much fainter blue than the others I’ve taken…like it is possibly less concentrated(?) Anyhow, I could tolerate the flavor right out of the dropper unlike any others I’ve tried, but I’ll probably try a new brand next time as this wasn’t my favorite.
