Frequently Asked Questions

Answers to common questions about legality, quality verification, shipping, payment, and lab handling of research peptides.

Quality & COA

Do I receive a Certificate of Analysis (COA)?

Yes — every order ships with a batch-specific COA. The COA shows HPLC purity percentage, LC-MS identity confirmation, batch number, synthesis date, and manufacturer ID. You can also browse COAs in advance at the COA Library.

What does ≥99% purity mean?

By HPLC, the target peptide accounts for at least 99.0% of the area under the curve. The remaining ≤1% consists of synthesis-related impurities.

How is identity confirmed?

By LC-MS (Liquid Chromatography-Mass Spectrometry). The observed molecular mass is compared against the theoretical mass within ±0.5 Da.

Do you test for endotoxins?

Yes — endotoxin testing is performed on all batches via the Limulus Amebocyte Lysate (LAL) assay.

Shipping & Delivery

How fast do you ship?

Orders placed before 2 PM EST on business days ship the same day via UPS/FedEx Express. US: 1–3 business days. Canada: 2–5 business days.

Is shipping discreet?

Yes. All packages ship in plain outer packaging with no branding or product references.

What about temperature-sensitive compounds?

Insulated boxes with gel packs are automatically added for temperature-sensitive shipments. The cold chain holds 2–8 °C for 48–72 hours during transit.

Do you ship internationally?

Not at this time. We ship only to addresses in the US and Canada.

Payment

What payment methods do you accept?

Cryptocurrency (BTC, ETH, USDT), domestic bank wires, ACH/eCheck (for verified institutional buyers), and Zelle/CashApp for US orders under $1,000.

Is cryptocurrency safe?

Yes — crypto payments are processed through standard blockchain confirmations. We provide wallet addresses at checkout.

Do you offer net terms for labs?

Yes — verified academic and corporate research labs can apply for Net-30 terms after a credit review. Email support@vialpeplab.com to start.

Storage & Handling

How should I store peptides?

Lyophilized: -20 °C, sealed, protected from light. Reconstituted: +2 to +8 °C. Full protocol at Storage & Reconstitution.

How do I reconstitute a lyophilized vial?

Use bacteriostatic water. Slowly add 1–3 mL along the inside wall. Swirl gently — do not shake. Allow 30–60 seconds for full dissolution.

What's the shelf life after opening?

Lyophilized: stable indefinitely if returned to -20 °C immediately. Reconstituted: 14–28 days at 2–8 °C.

Orders & Returns

Can I cancel or modify an order?

Yes — before it ships. Email support@vialpeplab.com with your order number.

What if I receive a damaged or wrong product?

Photograph the package and contact us within 48 hours. We will replace damaged or incorrect items at our cost.

Do you offer bulk discounts?

Yes — over $500: 5% off. Over $1,000: 10% off. Over $2,500 qualifies for institutional pricing.
