for everyone who is interested.
There are ways of preserving oxidation and degradation.
This is a picture of a test series. All vials contain the same amount of D9 diluted in a solvent, plus additional preservation recipes.
-Vial 1 left side is pure D9
All samples were penetrated with UVC light for quick degradation.
If I will find the time I will check the HPCL results in the next few days. I will update it here.
Wish ya all a nice weekend.
