Questions before you order

Short synthetic amino acid chains for lab work, not end-user consumption. They help study biological pathways in controlled models.

We typically state ≥99% by HPLC; MS identity data may be available. Deviations are documented per batch.

Yes, on request for the batch shipped, when available.

At audited partners under GMP- or ISO-oriented processes. CoA data is matched to the shipping batch.

Default is lyophilized active powder without excipients unless the SKU states otherwise.

Sales are RUO-focused. You confirm scientific use only at checkout.

For most compounds we provide sequence, mass, solubility notes, and storage guidance on request or on the product page.

Sequence length, modifications, purification effort, and batch size drive cost. Rare modifications cost more than standard tripeptides.

Weekdays usually within 24 hours, often faster.

Dry, dark, ideally -20°C. After reconstitution keep 2–8°C and use soon; avoid repeated freeze-thaw of solution.

Water was removed so the sequence stays stable in transit. Reconstitute with a suitable solvent before experiments.

Dry material tolerates shipping temperature spikes better than pre-mixed liquids.

Yes, -20°C is standard. After reconstitution prefer refrigeration over repeated freezing.

Hours at room temperature are common. Prolonged heat or light accelerates degradation.

Heavy cloudiness, color shift, or particles: do not use; contact support with batch ID.

Sealed under controlled conditions to limit moisture and contamination.

Heat, UV, wrong pH, and poor solvent choice. Follow protocol and cold chain.

Lyophilisate often lasts months to years. Open solutions are much shorter lived.

Hydrophobic sequences may need buffer, co-solvent, or mild pH adjustment.

Within Europe plan roughly 5–9 business days after dispatch.

Yes where import and local RUO rules allow. You handle customs at destination.

EU shipments usually include DHL or equivalent tracking.

We notify you proactively. Choose refund, substitute, or wait for restock.

Check address and tracking, allow normal buffer, then carrier or our support.

Send photos of box and contents; we arrange replacement or refund.

Often possible until the label prints. Contact us early.

Outer cartons are neutral with no peptide or lab branding.

Card, Apple Pay, Google Pay, PayPal, Revolut Pay, and SEPA via PCI-compliant providers.

TLS sessions; card data stays with the payment provider, not in our shop.

No fixed minimum amount.

Unshipped orders can be cancelled via support.

Try another method or contact support. Cross-border transfers may be held for review.

No persistent storage of sensitive payment data on our side.

No general return right on opened research material. Goodwill for documented quality deviation within 14 days.

Check local chemical, drug, and import rules. We supply as RUO, not as a medicine.

The ordering institution or person for acquisition, storage, and use in their jurisdiction.

No. Content describes research context, not human use.

We do not replace legal counsel. Clarify import and use before ordering.
