Don't confuse red phosphorous and hypophosphorus acid. They are not the same creature at all, and the reaction is not the same. Placebo's synth works fine, makes meth, and done properly gives good dope. I learned it, did it, succeed with it, and no longer do rP/I2 synths that way because I had better success and higher yields with the long wet reflux method. That is not a knock at Placebo at all. I just finally figured out there was an easier, if longer, route to the intended goal.
Hypophosphorous acid is more for the impatient among us. It is the fastest completing HI synth I have done, has the most consistent results and best yields of purest product of any of the standard HI synths. But do not follow Pebble's synth. Do follow monkeyboy's suggestions in hypotale, or study the contributions to the field that Shorty has made over the last year or so. The hypo cook done correctly yields very good product. And it can be done with a good deal more safety than I did it when I was fooling around boiling down hypo to concentrate it a few years back.
Giving consideration to the ability to obtain phosphorous acid legally I suggest you also consider that method as it works quite well as posted and the meth you make that way works just like the meth you make either of the other two ways.
