I'm an older head who is quite familiar with nitrous oxide. Back when I first received it at the dentist as a kid I fell in love. In the 80s and 90s I chased Phish and the dead and was a big fan of lot balloons. Recently I've gotten into isi they feel just like the old balloons I used to get. I've even experimented with Marz after seeing it on here and was impressed. So being a veteran nitrous head I decided to try galaxy gas when it came out. Guys. This stuff is not nitrous oxide. It made my ears ring and sent off alarm bells internally. The high felt dirty and more like poppers or huffing than nitrous oxide. Isi and marz had me tripping and felt clean. This galaxy gas had such a weird buzz and felt dirty. Felt nothing like nitrous I've tried. I suspect the manufacturer is adding other gasses that aren't safe for human consumption as this isn't sold for human consumption. If you contact a manufacturer of nitrous over seas and look at all the gas they can make its insane. Someone needs to lab test galaxy gas and see what it is
