Would that be a hazard keeping it for 3 weeks in fridge?

It wouldn‘t. You need to get purified water for injections and refrigerate of course. That‘s easily good for 4 weeks. If you use bac, or saline, the solution gets too hypertonic and your test subject will likely get osmotic injection damage at the injection site. Probably won‘t kill, but sting/burn for a bit. 3ml works with an 80mg klow vial (from experience). No experience with 2ml, could be slightly too concentrated.

this was the msg^^. It was about KLOW though.

Damn. This person has no idea what they’re talking about and this is harmful advice

This is extremely harmful advice, are you serious? PURIFIED water??? Might as well use filtered toilet water. The sting isn’t from bac water, it’s from the copper. Reconstituting with more bac water helps REDUCE the sting

The sting is not from the bac water, nor the copper. It is from the hypertonic solution. There is nothing harmful about the advice. There is an interview with Janoshik on Youtube, where Peter mentions it (water for injection purposes) himself, if you trust that source. For most peptides with less dissolved substance, Bac Water is totally fine. These are all valid injection reconstitution options, I would use them depending on circumstance. But if you are fine with the sting, you do you.

Of course sterile purified water. I also wrote sterile in one of the earlier messages, as far as I remember. If I say saline solution, I also don't expect you to use filtered ocean water. About the sting: I am using KLOW since a long time. It doesn't sting if prepared as I suggested. At all. It's all dose dependent. Any acid can burn you, it depends on the solution. Same with BAC Water. Pure Alcohol would not be good for you. But 0,9% in solution is not a big deal. At least for most people. Ultimately I was just sharing my experience. You can try it with your test subject, or not. It's not that I would believe anything anyone says on here before I try to understand it myself. Peace.
