Price Per Dose: Comparing Peptide Products Honestly
Bottle price is close to meaningless. The arithmetic that makes two products actually comparable.
In short
- Compare cost per day at the labelled serving, not per bottle.
- Then compare cost per milligram of the actual active.
- Subscription pricing changes the real number more than discounts do.
Why bottle price misleads
Bottles differ in count, in capsules per serving and in dose per serving simultaneously. A cheaper bottle can easily be the more expensive product per day, and the label is not trying to make that obvious.
A sixty-capsule bottle at two capsules per serving is thirty servings. A sixty-capsule bottle at one capsule per serving is sixty. Same count, double the duration.
The two calculations
Cost per day: bottle price divided by servings per bottle, where servings per bottle equals total units divided by units per serving. That single step resolves most apparent price differences.
Cost per milligram of active: bottle price divided by total active in the bottle, where total active is dose per serving times servings. This one exposes underdosed products that look cheap per day because they contain less.
Run both. A product can win on one and lose badly on the other.
Adjustments that matter
Salt form and label basis: if one product states peptide content and another states salt weight, they are not on the same basis and the comparison needs correcting.
Proprietary blends: where you cannot determine the amount of the active you care about, cost per milligram cannot be calculated at all. That is worth weighing in the decision.
Route: an oral product and an injectable are not comparable on milligrams under any adjustment.
Subscriptions and shipping
Subscription discounts are real savings if you would have reordered anyway, and a cost if they enrol you into shipments you did not want. Check the cancellation route before subscribing, not after.
Shipping matters at low order values and disappears at high ones, which is exactly how free-shipping thresholds are designed to work. Include it in the per-day figure.
What price cannot tell you
Cost per milligram says nothing about whether the milligrams are what the label claims. A cheap product that has never been independently tested is not good value; it is an unknown quantity at a low price.
Do the arithmetic to narrow the field, then choose within it on testing, disclosure and manufacturing. Price is the last filter, not the first.
