One flavor outsells everything else in this category, and it is not close. Blue Razz sells out across the range — 250mg, 300mg and 1000mg — and there is a real reason behind the preference.
The taste: sharp, tart, electric
Blue Razz is a tart blue-raspberry profile — think the candy version of a raspberry with extra acid. It is not sweet-first; it is sharp-first, with sweetness arriving as a second note. If sweet-deep flavors are your lane (Cherry Bomb, Grape Slushie), Blue Razz is the opposite end of the dial, and that is exactly the point for the people who like it.
Why tartness wins functionally
Here is the part most flavor discussions skip: tart profiles mask bitter alkaloids better than sweet ones. Sweetness rounds an edge; tartness interrupts the perception of it. For a product where the active ingredient is inherently bitter, the sharpness of Blue Razz does genuine flavor-engineering work, and the result is a chew that tastes like a candy before it tastes like a product. This is a big part of why first orders pick it, and why second orders re-order it.
The availability pattern
Because it is the demand leader, Blue Razz is the flavor most likely to show stock variation between strengths. If your preferred strength is showing as low or out, the other two strengths with the same flavor are the practical fallback — same flavor, different per-tablet dose, per the strength chooser. And if you want the berry family more broadly, the berry flavors guide and the berry collection map the rest.
Which Blue Razz to buy
New to 7-OH: the 250mg (50mg tablets) is the sensible first strength for a Blue Razz first order — the 180mg range does not carry Blue Razz, and the 1000mg is not a first-order product. Established: take whichever strength matches your routine. All three are in the shop, with batch documentation per the lab testing process.
