Peptide price per mg calculator
Put a quote in each card and read the price per milligram off both. It is the only figure that compares a 2 mg vial with a 10 mg one, or this shop with any other, and it takes two numbers and a division.

The arithmetic, in full
Price per milligram is the box price divided by the milligrams in the box, and the milligrams in the box are the strength of one vial times the number of vials. Nothing else belongs in it: not freight, which to a US address is included from $1,000 of goods and quoted below that, and abroad is quoted by the desk, and not a discount tier, which moves the price and not the arithmetic.
Worked on a line from this list: Glutathione 1500mg x 10 vials is $53.80 a box. The box holds 10 vials of 1500 mg, so 1500 times 10 is 15000 mg in the box, and $53.80 divided by 15000 is $0.00359 per mg.
The trap the figure exists to catch is that a bigger vial is almost always cheaper per milligram, because the vial, the fill, the stopper and the testing cost about the same whatever the vial holds. A quote that looks cheap per box can be the most expensive thing on the page per milligram.
Why the figure falls with vial size, and when the cheapest milligram is the wrong buy: price per milligram, how to compare vial strengths.
The twelve best-priced lines here, per milligram
The twelve lowest per milligram of the lines sold in milligrams, cheapest first; the price list carries every line. Four are special-order lines, sold only in 50-box lots and marked so beside the strength. Prices last revised 27 October 2026.

Comparing this shop with another supplier’s quote
The first card, A quote to check, starts filled with a line from this list. Put the other supplier’s quote in the second card, Anything to compare it with, and hold three things steady while you do it: the strength of one vial, the number of vials the price covers, and the price of the goods before freight. If the other quote is for a single vial, put 1 in the vials box. If it is in another currency, convert it first, because the calculator divides whatever you give it.
What comes back is the only figure that puts the two on the same scale, and the percentage underneath is the gap between them.
What a price comparison leaves out
Per milligram compares the price. It does not compare the article, and four things sit outside it that decide whether two quotes are the same thing at all. Freight, which attaches to an order rather than to a milligram: to a US address it is included from $1,000 and quoted by the carrier below that; abroad the desk quotes it. The minimum, because a low per-milligram figure on a quantity you cannot use is not a saving. The specification the batch is made to: for a peptide line the certificate reports purity by RP-HPLC, net content and identity, and the specification adds limits such as any single related substance, water and acetate. And whether a certificate comes with the batch at all, tied to the number on the box.
Those are on every line here: the compound pages print the specification a batch is released against, and any batch number can be checked on the certificate page. Compare the number, then compare what the number buys.
Where a price comparison website gets its numbers
A comparison is worth exactly what its inputs are worth, and most of the peptide price comparisons on the web are typed in by hand from storefronts that have moved on since. This shop publishes its own list as data so nobody has to do that: prices.csv and prices.json carry every line, its code, its strength, its box price and its per-unit price, with the date the list was last revised. Both are the same rows this page calculates from.
The whole list is on the price list, and it is downloadable as CSV or JSON if you would rather do this in a spreadsheet. Two lines side by side, with how their masses differ as well as the price, is what the comparisons are for.
Questions about price per milligram
What do I enter for a single-vial quote?
Put 1 in the vials box, the strength printed on the label in the milligrams box, and the price of that one vial before freight in the price box. The calculator divides whatever it is given, so convert a quote in another currency first.
Why compare per milligram rather than per vial?
Because a vial is not a fixed quantity. A 2 mg vial and a 10 mg vial are both one vial, and the second holds five times as much, so per vial compares nothing. Per milligram is the only figure that puts two different strengths, or two different suppliers, on the same scale.
Why is a bigger vial usually cheaper per mg?
The vial, the stopper, the fill, the labelling and the release testing cost about the same whatever the vial holds, so those fixed costs are spread over more milligrams as the strength goes up. Retatrutide shows it: $0.808 per mg in the 10mg vial against $0.453 in the 60mg vial, both sold by the single box. The far wider spread across the whole list, $0.00359 per mg for Glutathione against $31.160 for IGF-1 LR3 in 0.1mg vials, is the compound, not the vial.
Does the calculator send my figures anywhere?
No. The arithmetic runs in the page, in your browser, and nothing you type is submitted or stored. The page works the same with scripts switched off, minus the two input columns.
Does this include shipping?
No, and deliberately. To a US address, freight is included on orders of $1,000 and over and quoted by the carrier below that; abroad, the desk quotes it. Either way it attaches to an order rather than to a milligram. Put the goods price in and compare the freight terms separately.
Are your own prices in here?
The first card starts filled with a real line from this list, and this page’s table ranks the twelve lowest per milligram, and the price list carries every line. The full list, with the certificate specification for each line, is on the price list.
