Ive been having great success with 840, however it does seem like a number of people develop an adverse reaction to it over time, as reported on this forum.
These are the oil breakdowns components
MIG812 -> Glycerol and FFA
MIG840 -> PG + FFA
EO -> Ethanol + FFA
840 breaks down to PG, which seems like a pretty common allergen.
Either way, MCT (Mig812) will work.
That's how mig840 works, you can be fine for 6minths or few years or whatever 2/weeks but sooner or later your body will just say: nope,. No. More of this shit and BANG you get fucked

Propylene glycol was the most common allergen found (56.6%; 422/746).
With a triglyceride (regular oil), your body uses lipase and breaks down fat into glycerol and FFAs.
Not sure who thought injecting Mig840 chronically makes sense. Instead of glycerol,
propylene...
