Pill Aesthetics

[Masa]

Swim just got a new batch of pills and when he was stashing them away he noticed that they where a pure clean white when the ones he had left over from last time had off-white mottled appearance
This made him think of a thing he heard long ago when he had first started dropping that specked green and blue meant it had Ket in it
Though he always assumed the was very little actual fact behind this old bit of “clubbers wisdom” it made him wonder if the are another bits of info that ppl pass around the clubs
yes for a trust worthy test you need to go a bit more high tec but swim would think the appearance of the pill was a more reliable means than what it has stamped on it as any mixture could be poured into the press but different mixes of chems will produce different looking piils

So any bits of old wives wisdom either with or without science to back it up that swiy knows?
