Click Sign in in the navigation bar and enter the email and password associated with your researcher account. After verification, your profile details autofill on repeat orders and your orders dashboard stays in sync with lab status.

On the sign-in screen, choose Forgot password and enter your registered email. You will receive a secure reset link—typically within a few minutes. If the email does not arrive, check spam filters or contact our team for assistance.

After signing in, open your account dashboard to update contact details, shipping preferences, and organization information. Saved profile data carries forward to new orders so repeat submissions stay fast.

Our Purity & Quantity panel uses HPLC to measure peptide identity and purity against reference standards. Results include peak area percentages, main-peak purity, and quantity estimates where applicable—reported on your certificate of analysis.

Purity is calculated from chromatographic peak integration: the main peptide peak area is expressed as a percentage of total detected peak area after baseline correction. Impurity peaks, solvent fronts, and matrix artifacts are excluded per validated method criteria.

Your COA summarizes numeric purity, quantity where measured, method reference, and supporting chromatograms. A higher main-peak percentage indicates greater peptide content relative to detected impurities. Interpret results alongside your formulation, solvent, and intended research use.

Compare reported purity to your internal specifications and prior lots. Review impurity profiles—not just headline percentages—especially for complex matrices. Contact our team if you need method context, feasibility review, or help correlating HPLC traces with your submission notes.

After checkout, ship labeled vials to our receiving address with the printed barcode sheet inside the package. Use appropriate cold-chain or ambient packaging for your material. Label compound name, concentration, solvent, and batch reference clearly on every vial.

Shipping labels and barcode sheets are available in your orders dashboard after payment is confirmed. Download and print the label, affix it to your outbound package, and include the barcode sheet inside so intake can scan your order on arrival.

When you ship samples to the laboratory, retain your carrier tracking number. Inbound sample tracking is managed through your chosen carrier. Once testing completes, order status and COA availability are updated in your orders dashboard.

Turnaround begins when samples are received and logged at the lab. Each panel lists expected business-day ranges on its detail page. Partial results may appear in your dashboard before the full order is marked complete.

Place your order, print shipping materials, and send samples to the lab. Intake scans your barcode, verifies sample condition, and queues panels for analysis. Methods follow validated SOPs for HPLC purity, USP 71 sterility, and LAL endotoxin testing as ordered.

Your order status moves from awaiting samples to received, then in testing as each panel progresses. You will see dashboard updates as analyses complete. Incomplete or ambiguous submissions may require clarification before testing begins.

Completed panels generate certificate of analysis PDFs attached to your order. Reports include method references, numeric results, pass/fail determinations where applicable, and supporting traces for chromatographic work. You receive dashboard notification when documents are ready.

Browse the testing menu, add panels to your cart, and complete checkout. After payment you receive shipping labels and barcode sheets. Sterility and endotoxins can share one vial when ordered together; purity & quantity requires a dedicated vial.

Sign in and open your orders dashboard. Each order lists panel status and links to completed certificates of analysis. Partial results may display as individual panels finish before the full order closes.

Yes. Historical COA PDFs remain available on completed orders in your dashboard. Download and archive documents for your internal quality records or regulatory documentation as needed.

Panel pricing is listed on the testing menu and confirmed at checkout. Final totals include any configured processing fees. Multi-panel orders may combine compatible tests on a single submission where noted to reduce shipping overhead.

Requirements vary by panel. Purity & quantity typically needs at least 1 mg lyophilized or liquid material with concentration noted. Sterility and endotoxins require sufficient sterile volume for compendial intake. Visit each panel page for detailed specimen guidance.

Account and order information is used solely to process testing, deliver results, and support your submissions. We apply access controls, encrypted transport, and laboratory data-handling practices aligned with research confidentiality expectations. See our Privacy Policy for full details.

Orders are for custom analytical services. Refunds or credits are evaluated when testing cannot proceed due to laboratory factors or when intake issues prevent analysis. Contact our team promptly if you need to discuss an order before samples are processed.

Email admin@jcdresearch.com for order, method, COA, or feasibility questions. We typically respond within one business day. For urgent intake issues, include your order number and sample details in the subject line.
