Melanotan I
The least you can spend is $23.40 for 10mg at hightidecompounds. The lowest cost per mg is $1.89 at goalphalabs, though that is a $188.99 cart. Across 19 vendors, 95% of listings fall between $1.89 and $10.06 per mg — a 5.3x range for the same compound.
Lowest total for a single vial — the least you can spend to start.
What Melanotan I actually costs
Across the 19 US retail vendors we track, Melanotan I runs from $1.89 per milligram to a median of $3.45, with the dearest tenth above $10.06. Buying at the bottom of that range rather than the middle is a 45% saving on the same compound, and today that means goalphalabs.
The least you can spend to try it is $23.40 for a single vial. That figure and the cost per milligram rarely point at the same vendor — the cheapest way in is almost never the cheapest way to keep buying.
The best rate anywhere is $1.89/mg at goalphalabs, on a 10-vial pack totalling 100mg for $188.99. That is a real commitment against a single vial, which is why both numbers are shown separately below rather than blended into one ranking.
Why prices vary this much
Melanotan I prices vary by roughly 5.3× between the cheapest and dearest vendors we track, for what is nominally the same compound. Three things drive most of that gap.
Vial size. A 10mg vial at $25 and a 100mg vial at $150 look very different on the shelf, but the second is less than two thirds the price per milligram. Vendors are not obliged to make that comparable, and most do not. Normalising every listing to $/mg is the only way the field lines up.
Pack economics. Multi-vial kits routinely undercut single vials by a wide margin, because the vendor ships once and you carry the inventory. The trade is a much larger cart for a lower rate.
Positioning. Some vendors compete on price and some on presentation. With 19 vendors in the field and no obligation to disclose anything, a 192% premium over the median buys no guarantee of anything measurable.
How we work out cost per milligram
Every price here is read directly from the vendor's own store, not retyped from a screenshot or a spreadsheet, and carries the time it was read. We normalise each listing to cost per milligram by dividing the cart price by the total milligrams in the package — vial size multiplied by vial count.
Where we cannot read a dose with confidence, we publish no cost per milligram at all. Blends get no $/mg because dividing one price across several different molecules describes nothing. Capsules, nasal sprays and pre-mixed liquids are excluded from vial rankings for the same reason. A missing number means we would not stand behind it.
Common questions
What is the cheapest Melanotan I per milligram?
$1.89/mg at goalphalabs, the lowest of 19 US retail vendors we track as of the last check. The median across the field is $3.45/mg, so the cheapest listing is 45% below typical.
What is the least I can spend on Melanotan I?
$23.40 for a single vial. That is the lowest total cart, not the lowest cost per milligram — the two are usually different vendors.
Are multi-vial packs of Melanotan I cheaper?
Yes. The best pack rate is $1.89/mg at goalphalabs, against $1.89/mg for the cheapest single vial. Packs almost always win on rate and lose on upfront cost.
How many vendors do you compare for Melanotan I?
19 US retail vendors and 28 live listings, 28 of them in stock at the last check. We read each vendor's own store directly and re-check nightly.
Do you sell Melanotan I?
No. We sell nothing and ship nothing. Some outbound links pay a commission, which is labelled on the row, and ranking sorts on price alone — never on what a vendor pays.
Blends containing Melanotan I
These are separate products, priced per mg of total peptide across every compound in the vial. That figure is not comparable to the Melanotan I prices above — a cheaper blend is not cheaper Melanotan I, because you are also paying for the other ingredients.
