A rotation done well is the difference between a routine and a scavenger hunt: the right packs, the right flavors, the right timing, so that “what do I have left” is a question with a calm answer. Here is the complete structure.
Step 1: Pick two or three flavors, on purpose
The rotation is a flavor decision first. The pattern that works for most regulars: one workhorse (the flavor you actually reach for — for most people, per the flavor roundup, it is Blue Razz, Cherry Bomb or Mango), one contrast (the opposite side of the sweet-tart dial from the workhorse, so neither goes flat — the sweet vs tart guide is the two-minute picker), and optionally one occasional (a special flavor for the slower occasions, often a bar-format one). Three flavors is the ceiling of a practical rotation; five is a hobby, and the math below is for three.
Step 2: Match formats to the routine, not the other way around
The tablets vs bars comparison decides the split, and the usual pattern: the tablet format as the workhorse (the 300mg 30-count for fine-dose routines — its per-mg value is the best in the range per the cost per mg guide — or the 750mg/1000mg for established higher-dose routines), and the 400mg bars for the occasional slower chew. If you are doing tapering or reset work, the 30-count is non-negotiable — it is the only format that gives 2.5mg pieces (the tapering guide, the micro-reset guide).
Step 3: Know your consumption rate
The one number the whole system hangs on: tablets (or bars) per week, honestly counted from the log for two or three weeks. A 2.5mg-every-other-day routine uses roughly one 30-count per month-plus; a daily 50mg routine burns a 750mg pack in three weeks. The exact number is yours to measure — the reorder guide has the framework — and it is what converts “I’m running low” into “reorder now, ship window is 3–7 days U.S. / 5–12 days Canada” (U.S. guide, Canada guide).
Step 4: Time the order to the threshold
Reorder at roughly two weeks of supply remaining — early enough that the 1–2 business day processing plus transit does not create a gap, late enough that the pack is not sitting in storage for a quarter (the storage guide applies). And run the $90 free-shipping math at checkout: if the rotation order is within reach of the threshold, the third flavor (or a second workhorse pack) is the deliberate add, not the impulse. The price guide shows which packs make the threshold work hardest for your per-mg number.
Step 5: Store it right, or the rotation is fiction
A rotation that sits on a counter in the sun is not a rotation, it is a degradation schedule. Sealed, cool, dark, dry — the storage guide is four rules and a drawer. The packs that survive to their reorder date are the ones that stay at the strength the label and the batch report promise, which is the entire point of buying verified product in the first place.
The one-page summary
Two or three flavors (workhorse, contrast, occasional) · formats matched to routine (30-count workhorse, bars occasional) · consumption rate measured · reorder at two weeks of supply · free-shipping threshold hit deliberately · sealed and stored. That is the system. The full range is in the shop, and the FAQ answers the specific “which pack for my X routine” questions this guide frames.
