i am referring to the epithio steroid debate, and which molecular ion peak value is most consistent with the compound
I have tested hundreds of steroids on GC/MS. I know how they behave. So I am very confident in my opinion.
The molecular weight of the epithio steroid is 320. This steroid is known to easily lose a sulfur atom if heated. A double bond is left behind.

IN this article they demonstrate the pryolytic breakdown of the very similar 2alpha,3alpha-epithio-5alpha-cholestan to delta2-5alpha-cholestan at 130 C.
That gives you a molecular weight of 288. And that is the molecular ion peak we see with havoc and hemaguno. In fact this mass spectrum matches that of DMT (which if you lose the sulfur in this manner, you should get this)
It has been argued that the teritary alcohol at C17 can dehydrate. If this occured then you would have a molecular ion peak of 270
However dehydration of the C17 tertiary alcohol does not occur. I believe I can be considered a solid authority on this. I never shot in a 17alpha-methyl steroid that did this
If indeed this did happen, then if I were to shoot DMT into the GC/MS i would get a mass spectrum with M+ of 270. But i do not, i get 288, and it matches what is seen with hemaguno and havoc. I have tested DMT before, trust me.
Its 100% inarguable in my mind. The only possiblity is that hemaguno and havoc have DMT in them and not epithio. but other tests can confirm or deny this
