Individually boxed. Individually serialized.

Know your bottle. Check your seal.

Each bottle comes in an individual single-vial box with a serialized tamper-evident seal to help verify authenticity.

Check that the seal is intact before opening, and retain the unique serial number for reference.Check your serial ↗

Bottle images are illustrative mockups using the original label artwork. Peptide vials contain a small amount of lyophilized powder, not a full vial of powder; visible fill level may vary. Add products to your cart and request an emailed payment link. Reports describe the submitted supplier samples; a match to Big Boy Gains inventory has not been established.

Your bottle. Your unique number.

Check the seal.
Verify the serial.

Find the six-digit serial on your individual vial box’s tamper-evident seal and check it against the Big Boy Gains issued serial list.

A match confirms the number is registered. It does not prove the contents are authentic or replace checking the intact seal and purchase source.

Enter the digits exactly as printed on the seal.

You can check a registered number again at any time. Looking it up does not mark it as used.

Documentation, up front.

Read the report.
Check the source.

Two supplier-provided Janoshik reports are available to inspect. Search by task number, sample code, or the batch printed on the report.

Reports are supplied documents, not independently authenticated here. Purity and quantity results do not establish sterility or suitability for human use.
