Peptide vial codes.

Every code on a Helion vial.

Codes as printed on Helion labels and listed on each product page.

What each vial holds.

Peptide vial sizes are stated as the mass of peptide in the vial, not the volume of the glass. Helion's vials hold 5 mg (TSM5, tesamorelin), 10 mg (2S10 SS-31, MS10 MOTS-c, and the 5 mg + 5 mg blends CP10 and BB10) or 50 mg (CU50, GHK-Cu); bacteriostatic water is sold by volume, 3 ml (BA3). The lab report for each lot states the measured amount next to the labeled one, so the vial size can be checked against the COA Portal.

Letters for the compound, a number for the amount.

Each code pairs a short abbreviation of the compound with the amount in the vial: TSM5 is tesamorelin, 5 mg; MS10 is MOTS-c, 10 mg; CU50 is GHK-Cu, 50 mg; BA3 is bacteriostatic water, 3 ml. For the two blends the number is the total: BB10 and CP10 each hold 5 mg of one peptide and 5 mg of the other.

Codes like these are a labeling shortcut, not a standard. Other sellers may print similar codes for different compounds or amounts, so confirm what a vial holds from its full label and its lot's lab report rather than from the code alone.

What else to check.

• Compound and amount: the name and quantity behind the code.
• Lot number: ties the vial to one batch and one lab report.
• Storage: Helion labels call for 2 to 8 °C; the storage guide covers the rest.
• Research-use-only notice: on every Helion label.

Lot number to COA.

Find the lot number on the vial, open the COA Portal and choose the product: each published report names its lot, and that lot should match the vial. Products whose reports are still pending say so. The COA verification guide shows how to confirm a report with the lab that issued it, and how to read a COA explains each line.

Shop by code.

Every Helion product page shows its code in the title, along with the compound, the amount and the status of its lab report. Peptides ship lyophilized, and every order goes out by USPS Priority Mail.
