Everything you need to know about ordering, storing, verifying and working with AVREA research peptides. Can't find your answer? Contact our science team directly.
The legality of research peptides varies by jurisdiction. In most EU member states and the USA, unscheduled synthetic peptides may be purchased for laboratory research purposes. They are not approved pharmaceutical products and may not be sold or used for human therapeutic purposes.
Notable exceptions include: some peptides are controlled substances in specific countries (e.g., melanotan-II is prohibited in the UK; AICAR has been banned by some sporting authorities). Always verify the specific regulatory status of each compound in your country before ordering.
AVREA Laboratories sells peptides exclusively for qualified research use. By placing an order, buyers confirm that the compounds will be used only for legitimate in vitro or preclinical research in compliance with local regulations. We do not accept orders where we have reason to believe the intended use is not research-related.
"Research Use Only" (RUO) is a regulatory designation indicating that a product is intended for scientific investigation in a laboratory setting. It means the product:
This designation does not mean the compound is inherently dangerous — it means it exists outside the pharmaceutical approval pathway.
We do not require institutional affiliation for all orders, but we do require buyers to confirm that they are a qualified researcher and that the compounds will be used for legitimate research purposes. For orders requesting full COA documentation with raw analytical data, we request a research institution email address for verification.
We reserve the right to decline orders where the intended research use cannot be reasonably established.
AVREA peptides are produced in an ISO 9001-certified facility using validated solid-phase peptide synthesis (SPPS) processes. Our production partners apply GMP-aligned quality standards: validated synthesis equipment, in-process quality controls, batch documentation, and environmental monitoring.
Full pharmaceutical-grade GMP certification (EU GMP/ICH Q7) is not claimed, as this designation applies specifically to active pharmaceutical ingredients (APIs) for licensed medicinal products. Research-use peptides are manufactured to the highest achievable quality standards while remaining outside the formal pharmaceutical manufacturing framework.
Browse our Research Peptide Catalog, select the compound(s) and quantity, and add to cart. Proceed to checkout, where you'll confirm shipping details and select a payment method. You'll receive an order confirmation by email. Orders are typically dispatched within 1–2 business days.
We accept the following payment methods:
Credit and debit card processing is not currently available. Orders are dispatched after payment confirmation.
There is no minimum order. You may order a single vial of any available compound. Volume discounts apply automatically:
Orders can be cancelled or modified within 12 hours of placement, provided they have not yet entered the dispatch process. Contact us immediately via the contact form with your order number. Once a shipment has been dispatched, it cannot be recalled — in this case, a return or replacement may be arranged if the products are received in unsatisfactory condition.
All AVREA peptide shipments use temperature-controlled packaging designed for 48–72 hours of thermal protection:
Upon receipt, check the thermal indicator. If it shows temperature excursion, photograph it and contact us immediately before using the compound.
| Destination | Typical Transit | Service |
|---|---|---|
| EU (Western Europe) | 2–4 business days | Express courier |
| EU (Eastern Europe) | 3–6 business days | Express courier |
| UK | 3–5 business days | Express, with customs |
| USA / Canada | 5–9 business days | International express |
| Australia / Asia | 7–12 business days | International express |
Delays may occur due to customs clearance. International orders outside the EU ship with appropriate customs documentation. Customs duties/taxes are the buyer's responsibility.
Yes. All orders are shipped in plain, unmarked outer packaging. No product names, brand markings, or descriptions appear on the outer box. The return address uses a neutral identifier. This is standard practice for research chemical suppliers to protect researcher privacy and simplify customs processes.
In the event of a customs seizure for an order of compounds that are legal to import in the destination country, contact us with your order number and any customs documentation received. We review each case individually. For orders to jurisdictions where research peptides are clearly legal research reagents, we will offer a reshipping arrangement where possible.
We do not ship to jurisdictions where the specific compounds ordered are explicitly prohibited. It is the buyer's responsibility to verify import legality before ordering.
Every AVREA batch is tested using multiple independent analytical methods:
All testing is performed by an independent ISO-accredited contract laboratory. We do not self-certify purity.
Click the "Request COA" button on any compound product page, or submit a request via the contact form. Include:
COA documents are sent within 24 business hours. The full COA includes: HPLC chromatogram, mass spectrum, purity result, water content, heavy metals data, batch details, and third-party laboratory identification.
All AVREA peptides are released with a minimum purity of ≥98.0% by RP-HPLC. The actual purity of each batch is shown on the product page and is typically 99.0–99.7%. Batches that fail to meet the 98% threshold are rejected and not sold.
The batch purity data on our product pages reflects the actual third-party tested result for the current in-stock batch, not a minimum specification or marketing claim.
If you have independent analytical data (HPLC, MS) indicating that the received product does not match the stated specifications, contact us immediately with your order details and the analytical report. We will investigate and, where the discrepancy is confirmed, provide a replacement batch or refund. We take product integrity seriously — any confirmed specification failure triggers a batch quarantine and investigation of the entire production lot.
Immediately upon receipt:
Do not: store on bench at room temperature, open vials prematurely, or store near aromatic solvents.
The recommended solvent for most research peptides is bacteriostatic water (0.9% benzyl alcohol in water for injection). The benzyl alcohol inhibits microbial growth, extending the stability of the reconstituted solution to 28+ days at 2–8°C.
Some hydrophobic peptides (e.g., GHRP-2, HGH Fragment 176-191) may require 0.1% acetic acid in sterile water for initial dissolution. For cell culture work, sterile PBS (pH 7.4) is often preferred.

General stability windows for reconstituted peptides stored at 2–8°C:
These are conservative general guidelines. Compound-specific stability data is provided on each compound page and in the COA.
Mechanical agitation creates foam and introduces air bubbles. Many peptides have amphiphilic domains (hydrophobic and hydrophilic regions) that accumulate at the air-water interface. At this interface, shear forces and surface tension disruptions cause peptide unfolding and aggregation — permanently reducing purity and bioactivity.
Instead: inject solvent slowly along the inner vial wall, then gently swirl the vial (circular motion) until dissolved. If the peptide doesn't dissolve after 2–3 minutes of gentle swirling, refer to the troubleshooting section of our protocol guide.
Both peptides and proteins are polymers of amino acids linked by peptide bonds. The distinction is primarily one of size and structural complexity:
Research peptides in our catalog range from hexapeptides (GHRP-2 at 873 Da) to longer sequences like Retatrutide (~4916 Da with modifications). All are synthesised by SPPS and are chemically defined — not biologically derived.
HPLC (High-Performance Liquid Chromatography) separates compounds in a mixture based on their differential affinity for a stationary phase (column packing) and a mobile phase (solvent). For peptide purity testing, reversed-phase HPLC (RP-HPLC) is standard:
The peptide elutes as a peak; all other components (synthesis impurities, truncated sequences, deletions) elute at different times. Purity is calculated as the target peak area divided by the total peak area × 100%. A 99.3% purity result means <0.7% of the sample is anything other than the target compound.
Research peptides are produced by Solid-Phase Peptide Synthesis (SPPS), developed by Robert Bruce Merrifield (Nobel Prize 1984). The process:
The final product is a chemically defined, synthetic compound — no biological source material is involved.
