JointBrex comes in three package sizes: 2, 3 and 6 bottles. Each bottle is a 30-day supply at the labeled two-capsule serving, so the real question is how long a fair trial should run.
2 Bottles: A 60-Day Window
At $79 a bottle ($158 total, plus $9.99 shipping), 2 bottles lines up with the guarantee window itself. It carries the highest per-bottle price of the three tiers.
3 Bottles: The Popular Middle
At $69 a bottle ($207 total, free shipping), 3 bottles covers 90 days. The glucosamine and chondroitin trials that reported a benefit generally ran eight to twenty-four weeks, so three months gives a genuinely fair test.
6 Bottles: The Best Per-Bottle Price
At $49 a bottle ($294 total, free shipping), 6 bottles covers 180 days and carries the lowest cost per bottle. Because joint nutrition builds gradually, this is the tier most buyers choose.
Our Take
Given the research timeline behind these ingredients, 2 bottles is a tight window to judge results in. If you're planning a genuine trial, 3 or 6 bottles makes more practical sense.
