Reds = little/no euphoria, help sleep
White = some (sometimes a lot, depending on lot) energy and euphoria
Green = most consistent high euphoria, appetite suppression, high empathy/sociability
Yellow = like green but less consistent, usually a bit weaker
Gold = similar to yellow, batches vary wildly imo.
Never get let down with most greens unless your tolerances are high.
With StraightupK, the green maeng da and super green are always strong.
In all fairness, I’ve been dependent on the stuff, I heavily don’t recommend using more than 3-4x/week maximum. Dont believe any “safe as coffee” statements on the Internet. Daily use is asking for troubles.
