Question 1

When can I order?

Accepted Answer

Soon. Both solutions are bottled with published Certificates of Analysis, RU-58841 batch 30582 and pyrilutamide batch 41276. Orders open the moment stock lands. We will never take an order we cannot fill same-week.

Question 2

Are these products medicines?

Accepted Answer

No. Nothing we sell is a licensed medicine, and we don't make medical or treatment claims. RU-58841 and pyrilutamide are research compounds, sold strictly for laboratory research use, on identity and concentration data verified by an independent lab.

Question 3

Is the concentration actually what the label says?

Accepted Answer

Yes, and we prove it. Finished solutions are quantitatively assayed by an independent lab for actual concentration in mg/mL, not just powder purity. Batches release at or above the labelled concentration, never below. Batch 30582 assayed 55.08 mg/mL against its 50 mg/mL label; pyrilutamide batch 41276 assayed 5.26 mg/mL against 5 mg/mL.

Question 4

How do I pay?

Accepted Answer

Norwood Labs accepts card (Visa and Mastercard) through a secure checkout, UK bank transfer via Faster Payments, and crypto (BTC, ETH, USDT). Card is the fastest, with instant confirmation.

Question 5

How fast is delivery?

Accepted Answer

Orders placed before 2pm on a working day are dispatched the same day, tracked, with Royal Mail or DPD. Free UK delivery on orders over £70.

Question 6

How are batches tested?

Accepted Answer

Each batch is sent to an independent analytical laboratory (Janoshik) that assays it for purity. The batch-specific result is stated on a signed Certificate of Analysis, and every order ships with it. You can verify the CoA publicly with the batch key.

Question 7

What ships with my order?

Accepted Answer

The batch-specific Certificate of Analysis, an amber UV-glass bottle with a graduated glass dropper, and a QR code on the label that resolves to the CoA. Every bottle traces back to its batch.

Question 8

Can I return an opened bottle?

Accepted Answer

Once the amber dropper bottle has been opened, it cannot be returned. Unopened bottles can be returned within 14 days of dispatch.

Question 9

Do you ship internationally?

Accepted Answer

Not at this time. We are a UK-only supplier and ship to United Kingdom addresses only.

Question 10

Why amber glass?

Accepted Answer

The compounds in our catalogue are photosensitive. Amber glass attenuates UV and short-wavelength visible light, extending the shelf life of the specimen.
