What peptide testing actually costs
A single peptide, tested once, costs between nothing and US$1,195 depending on where you send it and what you ask for. That spread is not a market failing to settle on a price. It is four different questions being sold under one word, and the cheapest and dearest entries below are not doing the same work.
The figures here are every price the laboratories in this directory publish, quoted in the currency each one uses. Nothing is converted: a CAD figure rewritten as USD is a number the laboratory never quoted and you cannot check against their page. Roughly half the directory publishes nothing at all and quotes per job, which is shown as such rather than left blank.
Who is in this table. Every laboratory that will take a peptide sample, cheapest published figure first. Laboratories that quote per job sort last, because an absent price is not a high price.

Why the cheapest option is free, and what it costs you
Finnrick tests fifteen named compounds at no charge. The exchange is publication: the result goes into a public dataset and feeds its vendor rankings. If you want the number kept private you pay, which is the same transaction in the other direction.
That makes it the cheapest entry in this table and also the one with a condition nothing else here carries. It is also US-only, so a Canadian reader cannot use it to test a vial at all, only to read what other people's vials came back as.
The four things you might be buying
Identity answers what the compound is. Purity answers what share of what was detected is that compound. Net peptide content answers how many milligrams of active peptide the vial holds. Contamination testing (endotoxin, sterility, heavy metals) answers whether what else is in there matters.
A vial can be correctly identified, 99% pure, and badly underfilled. It can pass all three and still carry endotoxin. Prices that look wildly different are usually buying different subsets of that list, which is why the table below carries what each figure includes rather than the number alone.
The pattern across the directory: identity and purity alone sits around US$150 to CA$250. Adding measured content pushes it to roughly US$250 to CA$280. Adding the safety panel roughly triples it, and a full compendial release with USP <71> sterility runs to four figures because the method needs a fourteen-day incubation nobody can shorten.
What the price does not tell you
Two laboratories charging the same can be doing measurably different work. Purity by HPLC-UV against purity by tandem MS with a quantifier and a qualifier transition are not the same measurement, and only one of them survives a modification hiding under the peak.
Shipping is the other invisible cost. A Canadian sample sent to Prague or Phoenix carries international transit and a customs step; a domestic Canadian lab does not. On a CA$249 test, cross-border logistics can be a third of the total again.
Common questions
What is the cheapest way to get a peptide tested?
Free, if you are in the United States and testing one of the fifteen compounds Finnrick covers, and you accept that the result is published. Otherwise the lowest published figures in this directory are US$150 for a qualitative identity check and US$180 to US$195 for identity plus purity.
Why do some labs charge four times more than others?
Because they are selling a different test. The dearest entries include compendial sterility to USP <71>, which is a fourteen-day incubation, plus endotoxin, bioburden and heavy metals. The cheapest establish identity by retention time and stop there.
Does a higher price mean a better result?
Not reliably. It usually means more tests, not a better version of the same test. What does correlate with rigour is the method: quantitation against a calibration curve with a second-source standard is a stronger claim than an area-percent figure, whatever either one costs.
