Sermorelin costs roughly $36 to $67 per research vial from research peptide suppliers, or $99 to $149 per month through a telehealth provider dispensing compounded prescription sermorelin. Those two figures are not competing prices for the same thing — they are two different product categories with different contents, different legal status, and different buyers. This page breaks down what each actually costs, what drives the gap, and what to check before you order. All pricing was verified in September 2026.
For laboratory research use only.
How much does sermorelin cost?
The answer depends entirely on which form you are pricing.
Research-grade sermorelin is sold as a lyophilized powder in a sealed vial, typically 5mg or 10mg, priced per vial. Across the suppliers we checked in September 2026, a single vial ran from about $36 to $67 depending on strength and supplier. Buying multiple vials in a kit brings the per-vial cost down substantially — often to the low $30s.
Compounded prescription sermorelin is dispensed by a licensed compounding pharmacy against a prescription, usually through a telehealth provider, and is priced as a monthly subscription rather than per vial. That monthly fee bundles the medication with a clinician evaluation, ongoing protocol adjustments, and shipping.
The per-vial number and the per-month number are not comparable on their face, because they do not contain the same things. The sections below separate them properly.

Prices as listed on each supplier’s public product page, 11 September 2026. Supplier pricing changes frequently — verify before ordering.
The spread at the 5mg size is wider than most buyers expect: $45 to $60 for what is nominally the same compound at the same strength. That gap is mostly not about the peptide. It is about what else is in the price — testing depth, whether reconstitution solution is included, shipping speed, and margin. More on that below.
Bulk and wholesale kits
Per-vial cost falls sharply at volume. A ten-vial kit at $315 works out to $31.50 per 5mg vial, against $45 buying singles — a difference of $135 across ten vials, before accounting for paying shipping once instead of ten times.
There is a second reason labs buy kits that has nothing to do with price: lot consistency. A kit drawn from a single lot means vial ten matches vial one. If you are running anything longitudinal, mixing lots partway through introduces a variable you did not intend to introduce. Our sermorelin wholesale kits ship as ten vials from one lot, assayed by HPLC and mass spectrometry before that lot is released.
Pre-mixed nasal spray
Sermorelin is also sold as a pre-mixed intranasal solution, priced per bottle by total peptide content rather than per vial. Our sermorelin nasal spray runs $90 for 10mg, $135 for 20mg and $180 for 30mg, which carries a premium over the lyophilized vial because the solution, bottle and metered pump are included and no reconstitution step is required. Among research suppliers checked in September 2026, RCDbio listed a 10ml/10mg sermorelin nasal spray at $129.30. Note that bottle volume and peptide content are different measurements — some suppliers sell a 30ml bottle containing only 4mg of peptide, so compare on milligrams, not millilitres.
Compounded prescription sermorelin
This is a different category and worth describing accurately rather than dismissively.
Compounded sermorelin is prepared by a US-licensed compounding pharmacy and dispensed against a prescription written by a licensed clinician after an evaluation. Telehealth providers package this as a monthly subscription — AgelessRx, for example, listed $99 per month for the first month on a three-month plan and $149 per month thereafter as of September 2026, with the clinician evaluation, unlimited protocol adjustments, ongoing check-ins, and shipping included.
What you are paying for there is not primarily the peptide. It is the clinical infrastructure around it: a licensed prescriber, a compounding pharmacy operating under 503A rules, and continuing oversight. If you want sermorelin administered to a person, that is the lawful route, and the monthly price reflects a service, not a vial.
Research-grade sermorelin is not a substitute for that pathway. It is laboratory material sold for laboratory use, without clinical oversight, and it is not intended for human or veterinary use.
What drives the price difference
Five things account for most of the variation between research suppliers at the same strength.
Testing depth. “Third-party tested” covers a wide range. HPLC purity alone is the floor. Mass-spectrometry identity confirmation tells you the compound is actually what the label says. Endotoxin screening is a further step that not every supplier runs. Each layer costs money and shows up in the vial price.
Lot control. Testing a representative batch is not the same as assaying the specific lot your vial came from. Per-lot testing requires the supplier to track material lot by lot, which is operationally more expensive.
What ships with it. Bacteriostatic water, a reconstitution calculator, and cold-safe packaging are either included or they are line items you pay for elsewhere. A $45 vial that includes reconstitution solution is not the same offer as a $45 vial that does not.
Fulfilment speed and origin. Same-day dispatch from US stock costs more to maintain than drop-shipping from an overseas facility on a 7–14 day lead time.
Margin and volume. Suppliers moving more units can price thinner. Some of the spread is simply this.
Where to buy sermorelin
What to check before you buy
Whatever supplier you choose, these are the questions worth answering first. They apply equally to us and to everyone else.
- Is the material tested per lot? Ask whether testing covers the specific lot you will receive, not a representative batch.
- Who performed the testing? Independent third-party labs carry different weight than in-house results.
- What does the purity figure actually measure? HPLC purity and mass-spec identity answer different questions. A purity number without an identity confirmation leaves the more important question open.
- Is endotoxin screening performed? Relevant for a subset of research applications; not every supplier runs it.
- Where does it ship from, and how fast? Domestic stock with same-day dispatch behaves very differently from an international lead time.
- How is it shipped and stored? Lyophilized sermorelin is stable, but cold-safe packaging and clear storage guidance still matter.
- Is reconstitution solution included? If not, add its cost to the comparison.
- Is the supplier clear about research-use-only status? A supplier blurring that line is telling you something about how they operate.
Buying sermorelin online
Most research sermorelin is bought online, which puts the burden of verification on you. Three practical points.
Where the material actually comes from is the single strongest signal — a supplier buying direct from the production facility can tell you which lot you are getting; one buying through distributors usually cannot. Second, check that the listed strength and vial count are unambiguous; vague listings are a recurring source of disputes. Third, an identifiable business with a real support channel and a visible review history is worth more than a marginally lower price from an anonymous storefront.
Our material comes direct from the manufacturer rather than through a distributor, and bacteriostatic water is included with every vial.
Best place to buy sermorelin for research use
There is not a universal answer, and any supplier telling you otherwise is selling rather than informing. What there is, is a straightforward way to decide: price the vial including what ships with it, confirm the material is independently tested per lot and sourced direct from the manufacturer, and check the lead time against when you actually need the material.
On those three axes, here is our position honestly stated. Our 5mg vial at $45 was the lowest single-vial price among the research suppliers checked in September 2026, and bulk kits at $31.50 per 5mg vial sit below every listed tier price in that set. Our 10mg at $67 is at parity with Penguin Peptides, not below it — if 10mg singles are what you need, we are competitive but not cheapest by strength alone. Every lot is third-party tested for purity and identity before release and comes direct from the manufacturer, bacteriostatic water and a reconstitution calculator are included at no charge, and most orders dispatch the same business day from US stock.
If that matches what you are solving for, you can buy sermorelin in 5mg and 10mg research vials, or order wholesale kits for single-lot consistency across ten vials.
Analytical data for every lot is reviewed by Jay Cipollone, Founder & Research Lead.
Sermorelin is frequently studied alongside ipamorelin and tesamorelin; pricing for those follows the same per-vial structure.

Frequently asked questions
How much does sermorelin cost per month?
Research vials are not priced per month — they are priced per vial, and how long a vial lasts depends entirely on the study design. Monthly pricing applies to compounded prescription sermorelin from a telehealth provider, which ran $99 to $149 per month among providers checked in September 2026, with clinician evaluation and shipping included.
Why is compounded sermorelin more expensive than research vials?
The monthly fee covers a licensed prescriber’s evaluation, compounding by a 503A pharmacy, ongoing protocol adjustment, and continuing clinical oversight. The peptide is a small fraction of that cost. Research vials carry none of those services and are not a substitute for them.
Where can I buy sermorelin online?
Research-grade sermorelin is sold by laboratory supply companies, including MyGLP1Store, in 5mg and 10mg vials. Compounded prescription sermorelin requires a prescription and is dispensed through a licensed pharmacy, generally arranged via a telehealth provider.
Is sermorelin available over the counter?
No. Sermorelin is not an over-the-counter product. Compounded sermorelin for human use requires a prescription. Research-grade sermorelin is sold for laboratory use only and is not intended for human or veterinary use.
What should a sermorelin Certificate of Analysis show?
At minimum: the lot number matching your vial, HPLC purity, mass-spectrometry identity confirmation, the testing laboratory’s name, and the test date. Endotoxin results are an additional layer some suppliers provide.
Does sermorelin cost more in 5mg or 10mg vials?
A 10mg vial costs more in absolute terms but usually less per milligram. At our September 2026 pricing, 5mg is $45 and 10mg is $67 — $9.00 per mg versus $6.70 per mg.
