Protoflow Cost per Day: $2.63, $1.97 or $1.63?

Because a small number feels cheaper than a large total, and it helps buyers compare packs.

It is a fair device if used honestly. But a low daily figure on a large pack can hide the amount you commit. At $1.63 a day, a six-bottle pack is $294 up front. A man who stops after a month has paid for five bottles he may not use, unless the refund applies.

Twelve bottles, since each lasts 30 days, which is twelve times the bottle price of your pack.

Multiply the per-day figure in the table by 365 and you have your yearly cost. We leave the sum to you, because prices may change. Long-term use is unstudied, so the number matters most as a prompt to ask whether you want to commit that much to an unproven product for that long.

Compare the cost per serving, the number of capsules in a serving and the doses of the same ingredients.

A product that lists 300 mg of a herb in one capsule may supply less than one that lists 120 mg in a capsule of a standardised extract. The label rarely makes the comparison easy. Put the numbers side by side, and ask which lines you actually want. A short label is often simpler to price.

$1.63 to $2.63 a day, with the cheapest rate needing the biggest commitment.

Choose the pack by how sure you are, not by the smallest daily number.
