Peg

What's the diff. between PEG 300,400, or 600? Can one be used universally. I'm looking to make an oral winny, var, possibly dbol and adrol. I've located instructions on here, but some say to use PEG 300 and some say PEG 600? Thanks for any help.

Bump for a response. Anybody?

PEG stands for polyethylene glycol which is a polymer. When an organic molecule such a ethylene glycol is tied end to end multiple times you end up with a polymer, hence Polyethylene glycol.
In polymer chemistry you can have different types of organization such as single repetition or branching out etc.
You can also have different lengths of polymers.
PEG 300, 400, 600 simply refers to the length of the polyethylene glycol molecule.

This also effects there properties :
PEG 600 will be thicker (more viscous) then PEG 300
Also PEG 300 will have a lower boiling point then PEG 600

I hope this answers your question
