I really struggled to get it right and I wanna save people looking for the recipe some time so they don't have to go through all posts.
This is the recipe for 30 ml at 200 mg/ml:
1) Weigh out 6 grams of Reduced Glutathione powder and pour it in your mixing beaker.
2) Add around 20 ml of Bacteriostatic water and start mixing (I prefer magnetic stirrer).
3) After a couple of minutes a milky cloudy solution will form. To get it to completely dissolve you will need to increase te pH of the solution.
4) Add NaOH pellets or NaOH solution to your mix. Add it very slowly, ml by ml or a couple of mg by couple of mg. If you get the pH above 6.5 it will oxidize instantly turning red and ruining your product. Having a pH meter is a life saver. The solution will start clearing up before 4.0 but I like to keep my brew between 4.5 and 4.9.
5) Once you've achieved your desierd pH, the solution should be crystal clear.
6) Add bacteriostatic water up to 30 ml and mix for another 5-6 minutes.
6) You can now filter your solution into a vials through 0.22 micron filter (I prefer Nylon66).
7) Once you've done you should store your Glutathione. If you are going to use it in the next 1-2 months you can store it in the fridge under 5 degrees C. If you are not going to use it soon then you should put it in the freezer and unfreeze it when you are ready to use it.
