Price per bottle versus total commitment
The lowest per-bottle offer requires the largest upfront order. Compare what you will actually use with the total amount you must pay. A higher package size is not automatically better for a consumer still evaluating suitability. The advertised 3- and 6-bottle options include four digital bonuses, which do not change the clinical evidence for the supplement.
Shipping and checkout charges
The 2-bottle offer has an additional shipping charge on the seller presentation, while 3- and 6-bottle offers advertise free US shipping. The linked shipping policy has destination-specific fees and schedules; availability and the checkout total are the authoritative confirmation. See shipping details.
Read refund conditions before choosing quantity
The seller’s dedicated policy says it accepts unopened returns within 60 days of receipt, less shipping fees, and does not cover return postage. That is narrower than a marketing impression of an unconditional refund. Consider that practical cost when choosing a package.
