I want to summarize the salient details of all of these tests. First of all, let me get my nomenclature straight, since this seems to be a stumbling point we're all dealing with. Pardon my pedantry, but on net, it's for great justice.
Epi1: The first batch of epistane, which is pure by IBE's account.
Epi2: The limited 200 bottle run of epistane, which is being recalled by IBE.
Havoc: RPN's epithio product.
Hema: SFR's epitihio product.
Looking at the GC/MS data available for these four compounds, we have the following M+ for each:
Epi1: 270 @ 20.48
Epi2: 288 @ 17.28 and 286 @ 20.96
Havoc: 288 @ 17.28 and 286 @ 20.95
Hema: 288 @ 17.28
Epi1 is clearly the odd man out. It is radically different from all the other compounds. If it is pure, everything else isn't.
Epi2, Havoc, and Hema all have the same M+ at 17.28 min, and the first four fragmentation ions are the same. This suggests that they all might have the same active. However, because Hema doesn't have a secondary peak at 20.9* min, it is the odd man out of this subgroup.
Havoc and Epi2 both have a secondary peak, with the former occurring at 20.96 min and the latter occurring at 20.95 min. The M+ at both these peaks is identical, and the fragmentation ions are similar, although the data on Havoc is incomplete (the fourth page of the report from RTP is blank). Still, this suggests that the secondary peaks for these products represent the same compound.
Given all this, I think the following three conclusions are reasonable:
1) Epi1 is completely different from all the other products.
2) Epi2, Havoc, and Hema all contain the same active.
3) Epi2 and Havoc contain isomers of the active.
This is well and good, but we still have a lot of questions unanswered. The most pressing ones are as follows:
a) What is the correct peak and M+ combination that should be observed for the expected active?
b) What is the actual dosage of all of the tested products?
c) How do the isomers of Epi2 and Havoc affect product efficacy?
We're making progress toward a resolution here, but let's not go giving each other handjobs just yet.
