Identify the right compound before ordering
Two markers are enough to confirm a batch's identity, and both appear on the certificate of analysis:
- a length of 15 amino acids;
- a measured molecular weight of about 1,419.5 Da.
5 mg or 10 mg? Same compound, same purity, same certificate: only the amount in the vial changes.
Why choose this NEXUS reference
- Third-party verified purity: every batch is HPLC-tested by an independent laboratory and the certificate of analysis (COA) can be checked before ordering.
- Shipped from France: dispatched within 24 h on working days, delivered in 2–5 working days to France and 8 European countries. Free shipping from €120.
- Consistent quality: same supplier, same controls, same packaging from one batch to the next.
- Verified reviews: our customers leave their feedback on Trustpilot; we do not edit it.
Reconstitution and handling
The lyophilizate is reconstituted with bacteriostatic water, which keeps the solution preserved after opening. Add the solvent slowly down the vial wall, let it run, then swirl gently: no vigorous shaking, no vortex — shear denatures peptides. Our reconstitution calculator gives the concentration for any volume.
Storage
Lyophilized powder: -20 °C or below, protected from light and moisture; stable for years when unopened. After reconstitution: 2–8 °C, protected from light, with a reference shelf life of 28 days. For longer storage, frozen aliquots are preferable to repeated freeze-thaw cycles.
Common laboratory mistakes
- Comparing a 5 mg and a 10 mg vial at the same reconstitution volume. At equal volume, the concentrations differ by a factor of two.
- Using plain sterile water for a vial that will be opened several times. Without a preservative, the solution is no longer protected once the stopper has been pierced more than once.
- Vortexing the vial. Gentle swirling is enough, even if dissolution takes a minute.
- Repeatedly refreezing the reconstituted solution. Each cycle degrades a fraction of the peptide. Aliquot at reconstitution.
Frequently asked questions
How can the batch's identity and purity be checked?
Every batch comes with a certificate of analysis (COA) from a third-party laboratory: HPLC purity of at least 99% and measured molecular weight, expected around 1,419.5 Da. It can be viewed from the Quality page and on request before ordering.
Should I choose the 5 mg or the 10 mg vial?
Both contain the same compound; only the total mass changes. It is a protocol choice, not a different product.
What should this peptide be reconstituted with?
Bacteriostatic water, which keeps the solution preserved after opening. Plain sterile water is unsuitable once the vial is pierced more than once.
How long does the reconstituted solution keep?
28 days at 2–8 °C, protected from light. Beyond that, frozen aliquots are preferable to repeated freeze-thaw cycles.
Where is the order shipped from and how fast?
From France, within 24 h on working days. Delivery to a pickup point or to the door, in 2 to 5 working days depending on the country. Free from €120.
In what context may this product be used?
Exclusively for laboratory and in vitro research. It is not intended for human or animal consumption, nor for diagnostic or therapeutic use.
NEXUS Quality Standard
Every NEXUS research compound is produced under strict quality control procedures. Each batch undergoes independent analytical testing to verify identity, assay accuracy, purity, microbial safety, endotoxin levels, heavy metal screening, and full batch traceability.
