EU Peptide Sciences lists 2 amidated neuropeptide analogues in this category, each supplied for laboratory research only and released against third-party analysis. Prices start at $70. Orders ship worldwide to eligible destinations, with free express delivery on orders of $250 or more.
The amidated N-acetyl forms in this group are used where greater resistance to peptidase activity is required than the parent sequences provide.
Choosing between amidated neuropeptide analogues
Compounds inside a category rarely substitute for one another. They differ in target, in sequence length and in the modification that controls stability, and those differences decide which model system each one suits. The specification table on every product page lists sequence, molecular weight and CAS number where they are on record, which is the fastest way to confirm that two listings describe the same substance.
Presentations of the same compound differ in quantity and price per vial, not in the compound, so a study can start with one presentation and move to a larger one once the method is settled.
Neuropeptide research compounds in stock
- n-acetyl semax amidate 30mg ($75.00) — a heptapeptide based on ACTH (4-10) with a Pro-Gly-Pro extension and no corticotropic activity.
- selank amidate ($70.00) — a synthetic analogue of the endogenous tetrapeptide tuftsin with a stabilising tripeptide extension.
What the research covers
Published laboratory work on amidated neuropeptide analogues is indexed in PubMed, and the studies that matter most for method design are the ones that state their model system plainly. Every compound listed here is used in vitro or in animal models; none of the work described is clinical.
When a protocol is transferred between laboratories, the variables that travel badly are concentration, diluent and storage interval. Fixing those three before the first assay saves more time than any change of compound.
Where two compounds in neuropeptide research compounds address overlapping pathways, running both arms in one assay under identical conditions is the only reliable way to separate potency from selectivity.
Reading a neuropeptide research compounds listing
Four fields decide whether a listing is the material a method needs. The CAS number is a unique registry identifier and the safest way to confirm two suppliers describe the same substance. Molecular weight is required whenever a molar concentration has to be prepared. Sequence notation runs N-terminus to C-terminus, and terminal modifications are part of the molecule’s identity. Purity is method-dependent, so the method belongs beside the number.
Quantity is the field most often misread. A listing that states a total across ten vials is not the same as a listing that states the content of one vial, and the difference matters when a protocol is costed.
Testing and documentation
Every batch across neuropeptide research compounds is analysed by an independent laboratory before release. Identity is confirmed by mass spectrometry and purity by HPLC, and the certificate of analysis is issued against the batch reference printed on the label. Request it at any point, before or after ordering.
A purity figure without a method beside it tells you very little, and a certificate with no batch reference cannot be tied to the vial in your hand. Both appear on the documentation issued here.
Storage and handling
Lyophilised material belongs in a freezer at -20 °C, sealed and protected from light, and should be brought to room temperature before the vial is opened. Reconstituted solution is held at 2–8 °C and should not be repeatedly frozen and thawed. Capsules stay sealed and dry at ambient temperature; topical solutions stay cool and dark.
Ordering, payment and shipping
The minimum order is $100. Payment is handled manually: after you place an order, our team emails payment instructions to the address on the order, and the order is processed once payment is confirmed. Cryptocurrency payments receive a 5% discount.
Orders ship worldwide to eligible destinations in plain, discreet packaging with tracking. Standard delivery takes 7–14 business days and express 3–7 business days, with rates calculated at checkout. Orders of $250 or more ship express free.

Questions about neuropeptide research compounds
Are these compounds for human use?
No. Everything in neuropeptide research compounds is supplied strictly for laboratory research and must not be administered to humans or animals.
Can I see a certificate of analysis before ordering?
Yes. Ask for the certificate covering the batch currently in stock and it will be sent by email.
Do you ship outside the European Union?
Yes. Orders ship worldwide to eligible destinations, with standard delivery in 7–14 business days and express in 3–7. Purchasers are responsible for confirming that import of research chemicals is permitted at the destination.
How do I pay?
Payment is handled manually. After you place an order our team emails payment instructions, and cryptocurrency payments receive a 5% discount. The minimum order is $100.
Laboratories new to neuropeptide research compounds usually start with a single presentation, confirm that the material behaves as the method expects, and then move to larger quantities.
Documentation is worth requesting before the first order rather than after a result looks wrong. A certificate of analysis names the method, the batch and the date, and those three facts are what let a result be defended months later.
Every listing in neuropeptide research compounds states the quantity supplied, the presentation and the storage condition. Where a field is absent it is absent from the batch record too, rather than omitted for brevity.
If a compound you need is not listed here, it may sit in an adjacent category: blends are catalogued by their primary action, and capsule formats are grouped separately from lyophilised vials.
Research use only. Products in neuropeptide research compounds are research chemicals. They are not medicines, supplements or cosmetics, and carry no therapeutic indication.
