Glad to hear of your experience with both PGE-2 as well as PGF2a. Let me ask you did you experience any side effects like the nausea or intense burning like I have heard exist for PGE-2? I heard of the nausea as well with the PGCL, which I also have some of in full enclosed glass vials. I have to use a razor to open these. In your experience what dose causes nausea with the PGF2a, is it when it reaches a certain proportion of the PGE-1 or is there a general rule of thumb? Hope I can find that other thread your talking about.
