The STR82E or the Egull Method will work.
It just so happened that when Ibee had first hand experience with Eph, he was visiting a fellow bee who had aquired them from a reliable source who aquired them from overseas. 5 sacks of 1000 pills.
The word was handed down to pay the asking price and Ibee was kinda shocked when the numbers didn't add UP against the sellers implied weight after extraction.
5000 pills were split in two and the first half were birched after only a tetra wash. Not quite GUPchucking but Ibee insisted on working his magic on the second 2500 in order to show the improvement experienced when bioassaying. The egull was performed on the second half by Ibee while the cook worked his magic in the blue lagoon
When the first batch came up short against the implyed the 25mg that the owner thought he had, Ibee and crew had the proof that somebee was fibbing at the point of sale.
Upon pinning that source down, he swore that he was told they were 25mg and had no way to test on short notice.
Yeah well long story short....these buggers weighed in at 60mg whole pill weight.
But only contained 12.5mg. And that # was sketchy to boot upon final weight of obtained reduced.
What a bite in the ass when you're expecting around 100g and only able to walk away with less than 50g.
Bulk extracts are a bitch....but a sure way to determine what ya got is to take a set small batch number....say 80 pills and do an egull on them(By the way....the Egull worked like a charm on these and everybee hitting the tube from the egull extracted birched goodz noticed the stronger difference on the first blast.)
80x25mg=2g expected
80x12.5mg=1g expected
Ibee noticed during that first ephedrine exp that it takes more alky pulls of the Pillmass than it takes when working with pfed. Must be a solubility difference in alky between pfed and eph!
Side by side testing was done on those Eph pills between ISO and Denat
Denat pulled more E xtals per equal pull than ISO.
