Sermorelin price: what actually reaches your card
The sermorelin price on the listing we link moves through three numbers before it settles. The original list price is $99.99. The site price is $72.00. The code PEPTIDEDECK takes a single vial to $36.00, which is the figure that reaches your card on a one-vial order before postage.
All three of those numbers were set by the same seller, which is worth saying out loud on a page about price. A discount measured against a list price the discounting party also chose is not a market rate, and there is no reference price for this compound to check it against. No formulary lists a sermorelin product, because the approved one, Geref, is discontinued and there is no current US label to price.
We earn a commission if you buy through our link, which is set out on our affiliate disclosure page. It is the reason we print the $99.99 beside the $36.00 rather than only the half that flatters the offer.
| How it is quoted | Figure |
|---|---|
| Original list price | $99.99 |
| Current site price | $72.00 |
| With code PEPTIDEDECK | $36.00 |
| Per mg on the 10 mg label | $3.60 |
| Per mg on the 11.31 mg assayed | $3.18 |
| Overfill measured on lot 38-01260229 | 13.1% |
Every figure below describes the same 10 mg vial on the listing we link.
Cost per milligram, and the lot that moved it
Per milligram is the only unit that survives a comparison between sellers. On the 10 mg label, $36.00 is $3.60 per milligram. Do that division on every listing you look at, because sellers quote in whatever unit flatters them: per vial, per kit, per box of five, occasionally per gram, which produces a number so small it stops carrying meaning.
There is a second figure here, and it is the more interesting one. The certificate for lot 38-01260229 reports 11.31 mg of material measured against a 10 mg label, which is 13.1% more than the vial claims. Divide $36.00 by 11.31 and the effective cost is $3.18 per milligram. That is a real measurement, made by MZ Biolabs on 7 February 2026, and it is a measurement of that batch alone.
Which is why it needs the caveat every time it is quoted. Overfill is a property of a fill run, not a specification. Another lot may assay differently, and nobody promises 11.31 mg on the vial you receive. Use $3.60 when you are budgeting and $3.18 when you are describing what one lot actually contained.
Quantity tiers and the $250 shipping line
With one vial size on the listing, the only volume lever is quantity. Three vials take three per cent off the list price, five take five per cent, and ten take ten per cent. Those percentages come off $99.99 rather than off the discounted figure, and whether a tier and the code can be applied in the same cart is not documented anywhere we can point to. We will not guess at it. Build the order both ways and read the total on screen.
Free shipping starts at $250. A single discounted vial at $36.00 is nowhere near that line, so postage is usually charged on small orders and belongs inside your per-milligram figure before you call the price good. On a $36.00 order, shipping is a meaningful share of the total rather than a rounding error.
There is a reason not to buy deep purely to move a percentage. Every extra vial bought to save three per cent is a vial you are betting you will still want later, and a certificate that describes your first lot describes nothing about your tenth. The discipline that makes the per-milligram figure useful is the same discipline that makes stockpiling a worse deal than it looks.
| Quantity | Discount off list | Per vial | Per mg on label | Clears free shipping |
|---|---|---|---|---|
| 1 vial | None | $99.99 | $10.00 | No |
| 3 vials | 3% | $96.99 | $9.70 | Yes, $290.97 |
| 5 vials | 5% | $94.99 | $9.50 | Yes, $474.95 |
| 10 vials | 10% | $89.99 | $9.00 | Yes, $899.90 |
| 1 vial with code | Code applied to the site price | $36.00 | $3.60 | No |
Tier percentages come off the $99.99 list. Whether they combine with the code is not documented, so check the cart.
What a very large discount usually means
A code that removes 64% of a list price is telling you something about the list price. In a market with no reference point, the list is a positioning number rather than a valuation, and the discounted figure is closer to the real one. That is not unique to this seller; it is how the whole category is priced, and our page on discounting in this market takes the pattern apart.
The corollary is that comparing two sellers on the size of their discounts is meaningless. Compare the landed cost per milligram, including postage, and then compare what each certificate covers. A seller charging more per milligram with endotoxin and sterility testing on the batch document is not more expensive in any sense that matters.
One more sanity check is worth running on any sermorelin price you find elsewhere. Multiply the quoted per-milligram figure by ten and compare it against $36.00. Far above, and you are paying for packaging, a reshipping margin, or a brand. Far below, and something has been taken out of the operation, which in this market is almost always third-party batch testing or domestic warehousing. Neither result proves anything on its own. A large gap in either direction is simply a question that deserves an answer before you pay, and the answer is usually visible on the certificate rather than on the product page.
Within the research market, $3.18 to $3.60 per milligram is unremarkable, which is the useful thing to know. Research peptides commonly sit in the low single digits of dollars per milligram, and where a compound lands inside that band reflects synthesis difficulty and demand rather than quality. Use the figure to compare two sellers of the same compound, never to decide which compound is worth buying.
The research vial beside a compounded prescription
Here is the comparison most readers arriving at a price page actually want, and the reason it is unusual for this compound: the prescription column is real. Sermorelin was an approved medicine. EMD Serono held NDA 019863 for the diagnostic product and NDA 020443 for the therapeutic version, approved on 26 September 1997, both now recorded as discontinued on Drugs@FDA, with the record stating the discontinuation was not for safety or effectiveness reasons.
Because sermorelin acetate was a component of an approved drug product, section 503A permits a compounding pharmacy to work with it. So a reader comparing prices here is not comparing a vial against a fantasy. They are comparing a $36.00 laboratory purchase against a supervised route that includes an assessment, laboratory work, a labelled preparation and a record, and that costs meaningfully more in both money and weeks.
The two are not interchangeable and should never be presented as though they are. The table below sets out what each price contains rather than pretending the numbers are comparable. Our guide to how to get a sermorelin prescription covers the second column in full.
| Research vial | Compounded prescription | |
|---|---|---|
| Cash cost | $36.00 with the code | Higher, and not published here |
| Assessment before purchase | None | Prescriber, history and laboratory work |
| What the container says | A lot number and a research-use label | A pharmacy label naming the preparation |
| Testing behind it | One certificate: purity and quantity on this lot | Pharmacy standards for a compounded preparation |
| Record of what you received | An invoice | A prescription record |
| If something goes wrong | The vendor's policy, then your card issuer | Prescriber, pharmacy, licensing board |
| Time from decision to material | Days | Weeks, including laboratory turnaround |
What each price contains. We publish no monthly figure for the second column because we have not verified one.
The figure we will not print
You will notice no monthly clinic or pharmacy price on this page. That is deliberate. Quotes vary by practice, by state, by whether laboratory work and follow-up are bundled, and by whether a membership is attached. We have not verified a representative figure we would be willing to publish, and a plausible invented one would be worse than a gap.
The same discipline applies across our cost pages. Where a number is checkable we print it and say where it came from. Where it is not, we say so. On this page the checkable numbers are $99.99, $72.00, $36.00, $3.60 per milligram, $3.18 per assayed milligram on one lot, three tiers of three, five and ten per cent, and a $250 free shipping threshold.
What the $36.00 does not include is worth listing plainly. No prescriber assesses whether it suits you. No pharmacist checks it against anything else you take. There is no approved label, no patient information leaflet and no adverse event reporting route. On this lot's certificate there is also no endotoxin test and no sterility test, only purity at 99.79% and quantity at 11.31 mg. The price is low because the purchase is small.
