Research summary

A synthetic tuftsin-derived heptapeptide studied in anxiety-model, neuroimmune and BDNF-expression research. The QR code on the printed vial opens this product’s certificate of analysis; batch records are available on request at shoplotus12@gmail.com with your lot number.

How it’s handled

What arrives. A small sealed glass vial of freeze-dried powder under a crimp cap, and a batch number printed on the label that matches the certificate on this page.

How it’s stored. Sealed, in the fridge at 2–8 °C, out of direct light. Freeze-dried powder is stable for months this way; once reconstituted in the lab it is kept cold and used within weeks.

What “reconstitute” means. The powder in the vial is dissolved in bacteriostatic water before it is used in an experiment. This is a laboratory reference, not instructions for use.

What we don’t provide. Directions for use on a person or an animal. Everything here is supplied for laboratory research only, and we would rather say that plainly than pretend otherwise. Questions about handling, storage or a certificate: shoplotus12@gmail.com.

Questions, answered

Who tests the products, and where do I see the results?

Each batch is tested by Kalbio Biotechnology (Lake Forest, California), an ISO 17025:2017 accredited lab, by HPLC. The certificate is posted unedited, as the lab issued it, on this page for the size you select and on the lab reports page, where you can search by compound, batch or lot.

What does the QR code on the vial do?

Scan it with your phone and the certificate for that product opens — purity, method and the laboratory that ran it. The batch and lot are also printed on the label, so you can search for them on the lab reports page.

How fast do orders ship, and what does shipping cost?

Orders placed before 3PM ET on business days dispatch the same day, with tracking sent to your email. Standard Shipping (3–5 business days) is $9.99 and free on orders of $200 or more after discounts; express shipping (1–2 business days) is $24.99 and overnight is $49.99. Orders over $150 also get a free 10 mL bacteriostatic water. Shipping policy.

Where do you ship?

U.S. addresses only. We don’t ship internationally, to freight forwarders, or to P.O. boxes for express and overnight services.

How do products arrive, and how should I store them?

Compounds ship lyophilised in sealed glass vials, packed securely and tracked. The storage spec for each product is sealed, 2–8 °C, protected from light.

Are these products for human use?

No. Everything we sell is supplied strictly for in-vitro laboratory research — not for human or veterinary use, and not for any diagnostic or therapeutic application. We give no directions for use. Full wording on the research disclaimer.

Who can buy?

You must be at least 21 years old and confirm the research-use terms to order. Details are in the terms.

Can I return something or get a refund?

Because these are research materials, requests are evaluated case by case. A refund or replacement may be granted if an item arrives damaged, is materially different from the order description, or has a documented quality-control issue — request it within 48 hours of delivery with photos or documentation. Opened vials and products that have left controlled storage aren’t eligible. Write to shoplotus12@gmail.com with your order number and batch ID; we reply within 3 business days. Refund policy.
