Choosing a vial size
The trade-off is unit cost against the in-use window. A larger vial is always cheaper per milligram, but the clock starts once it is reconstituted: refrigerated solution is generally treated as usable for about 30 days. Unreconstituted lyophilate is stable far longer, so a large vial only makes sense if the powder can be held properly until it is needed.
- 5mg and 10mg — pilot studies, method development and single-assay work.
- 15mg to 30mg — multi-week bench arcs and repeat-assay work at a noticeably lower cost per milligram.
- 60mg and 120mg — programme-scale research and analytical batches; the lowest cost per milligram we offer.
The tirzepatide dosage chart shows how many draws each vial yields at common concentrations, which is usually the fastest way to decide.
How we verify every batch
Each production batch is analysed by independent laboratory HPLC for purity and by mass spectrometry for identity, and the Certificate of Analysis is specific to the batch in your vial rather than a representative sample from an earlier run. Material is synthesised by our Swiss pharmaceutical-grade manufacturer, held under refrigeration through fulfilment, and shipped in insulated packaging.

Buying tirzepatide — FAQ
Where can you buy tirzepatide for research?
Dr Jays Peptides supplies research-grade tirzepatide in seven vial sizes from 5mg to 120mg. Every order ships from our Jacksonville, Florida facility with a batch-specific Certificate of Analysis. Research use only — not for human or veterinary use.
How much does tirzepatide cost?
Price scales with vial size, and the cost per milligram falls as the vial gets larger. The table on this page shows live pricing and stock status for all seven sizes along with the per-milligram figure so the value comparison is explicit.
What purity is your tirzepatide?
Every batch is verified to ≥99.8% purity by independent HPLC analysis with identity confirmed by mass spectrometry, and the batch-specific Certificate of Analysis is supplied with the order.
Which tirzepatide vial size should a laboratory choose?
Smaller 5mg and 10mg vials suit pilot and single-assay work where the reconstituted in-use window matters more than unit cost. Larger 60mg and 120mg vials give the lowest cost per milligram for programme-scale work, provided the material can be consumed within the storage window.
How is tirzepatide shipped?
Orders placed before 2pm ET ship the same business day from Jacksonville, Florida in cold-chain packaging. Domestic delivery is typically 1–2 business days, and free shipping applies over $300.
Is tirzepatide legal to buy?
Tirzepatide supplied by Dr Jays Peptides is sold strictly as a research chemical for in vitro laboratory work by qualified professionals. It is not sold for human or veterinary use, and buyers are responsible for compliance with applicable local regulations.
