10-Vial Kit: What It Is, Concentration Math, and Where to Buy
Reviewed by the VendPeptides Editorial Team. Written from product labeling, the batch certificate of analysis and published literature. Last updated September 2026.
A 10-Vial Kit is a laboratory package of ten individually sealed vials of the same lyophilized research peptide, supplied together so that one batch certificate of analysis (COA) covers the entire set.
Peptides sold in this format, including tirzepatide and retatrutide, have been studied in published preclinical and clinical research literature, and the phase 2 trial reports for some analogs are available in peer-reviewed journals.
Common catalog names include RT (retatrutide) and TR (tirzepatide), and the 10-Vial Kit is sold in vial strengths of 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 50 mg, and 60 mg, with kit totals from 50 mg to 600 mg.
This guide covers what a 10-Vial Kit is, the concentration math for reconstitution by vial size, safe laboratory handling, and where to buy these research-use-only kits in the US.

What is 10-Vial Kit?
A 10-Vial Kit is a single order unit containing ten vials of the same lyophilized research peptide, each vial sealed separately and labeled with the peptide name, strength, and lot number.
The kit format is used in laboratory research because it keeps one batch and one COA across ten vials, which reduces variability between experiments compared with buying vials from different lots.
For research purposes only. Not for human consumption. The 10-Vial Kit is not approved for any medical or veterinary purpose, and it is sold strictly as a research chemical.
Each kit lists a total peptide mass, for example a 10 mg vial kit with ten vials contains 100 mg total, and the vial label and the batch COA are the authoritative source for the exact fill and purity.
10-Vial Kit, RT and TR: are they the same?
No. The 10-Vial Kit is a packaging format, while RT and TR are catalog abbreviations for two different peptides, retatrutide and tirzepatide.
RT refers to retatrutide, a triple agonist that has been studied in phase 2 research, and TR refers to tirzepatide, a dual GIP/GLP-1 receptor agonist that has been studied in metabolic research.
Both are sold as 10-Vial Kits at VendPeptides, and the vial label on each kit states the peptide name, strength, and lot number so the two are not confused in the laboratory.
For research purposes only. Not for human consumption.
What has 10-Vial Kit been studied for?
The peptides supplied in a 10-Vial Kit have been studied in published metabolic and receptor-signaling research, and the phase 2 trial reports for some analogs are available in the peer-reviewed literature.
This article describes published research neutrally and makes no claim about outcomes; the literature, not the product page, is the place to read study design and reported findings.
The 10-Vial Kit is not approved for any medical or veterinary purpose, and it is not for human or veterinary use. For research purposes only. Not for human consumption.
Readers should consult the published literature and the batch certificate of analysis (COA) supplied with each kit for identity, purity, and lot-specific data.
10-Vial Kit reconstitution and concentration by vial size
Adding 2 mL of bacteriostatic water to a 10 mg vial gives 5 mg/mL, and the same ratio scales across the 10-Vial Kit strengths.
| Vial size | 10-vial kit total | Diluent added | Resulting concentration | µg per µL |
|---|---|---|---|---|
| 5 mg | 50 mg | 1 mL (1,000 µL) | 5 mg/mL | 5 µg/µL |
| 10 mg | 100 mg | 2 mL (2,000 µL) | 5 mg/mL | 5 µg/µL |
| 15 mg | 150 mg | 3 mL (3,000 µL) | 5 mg/mL | 5 µg/µL |
| 20 mg | 200 mg | 2 mL (2,000 µL) | 10 mg/mL | 10 µg/µL |
| 30 mg | 300 mg | 3 mL (3,000 µL) | 10 mg/mL | 10 µg/µL |
The vial label and the batch certificate of analysis (COA) take priority over any table, so always confirm the fill volume and peptide mass on the label before calculating.
10-Vial Kit 10mg vial reconstitution
Adding 2 mL (2,000 µL) of bacteriostatic water to a 10 mg vial gives 5 mg/mL, or 5 µg/µL.
This is the most common working concentration for a 10 mg vial in a 10-Vial Kit, and it is the ratio used in the table above.
For research purposes only. Not for human consumption. Confirm the diluent volume against the vial label and the batch COA before use.
10-Vial Kit 5mg vial reconstitution
Adding 1 mL (1,000 µL) of bacteriostatic water to a 5 mg vial gives 5 mg/mL, or 5 µg/µL, matching the concentration of the 10 mg vial at double the diluent.
If a lower working concentration is needed, add 2 mL (2,000 µL) to the 5 mg vial to obtain 2.5 mg/mL (2.5 µg/µL).
For research purposes only. Not for human consumption. The batch COA and vial label are the authoritative reference for the actual fill.
How long does reconstituted 10-Vial Kit stay stable?
There is no single stability figure that applies to every peptide, so the batch COA and the vial label are the correct reference for storage and handling guidance.
Published laboratory practice generally stores reconstituted peptide solutions cold and protected from light, but the exact conditions depend on the specific peptide and its formulation.
For research purposes only. Not for human consumption. Refer to the published literature and the batch COA for peptide-specific stability data.
How to handle 10-Vial Kit safely in the laboratory
- Put on a lab coat, nitrile gloves, and eye protection before opening the shipping container.
- Work in a clean, designated area such as a laminar flow hood or a disinfected bench surface.
- Inspect each vial in the 10-Vial Kit for cracks, loose caps, or damaged lyophilized cake before use.
- Swab the stopper with 70% isopropyl alcohol and let it dry completely before adding any diluent.
- Add bacteriostatic water slowly down the inside wall of the vial to avoid foaming the peptide.
- Swirl gently to dissolve; do not shake or vortex, because agitation can denature the peptide.
- Label every vial with the peptide name, concentration, date, and lot number, then store it per the batch COA.
Warning: Poor sterile technique or unlabeled vials can lead to contamination or mix-ups, so always use aseptic handling and label every vial with its lot number and concentration.
Is 10-Vial Kit the same as semaglutide?
No. The 10-Vial Kit is a packaging format, and semaglutide is a specific GLP-1 receptor agonist peptide with a different sequence and different research history.
A 10-Vial Kit can contain retatrutide, tirzepatide, or another research peptide, but it is not semaglutide unless the vial label explicitly states semaglutide.
For research purposes only. Not for human consumption. Always match the vial label and the batch COA to the peptide you intend to study.
Is 10-Vial Kit safe for humans?
No. The 10-Vial Kit is sold for research purposes only and is not for human consumption; it is not approved for any medical or veterinary purpose.
The FDA treats research chemicals as laboratory materials and expects 'not for human consumption' labeling, so these kits are not drugs and have not been evaluated as such.
For research purposes only. Not for human consumption. Any human-use question should be directed to a licensed medical professional, not to a research supplier.
Can 10-Vial Kit be used for pets or animals?
No. The 10-Vial Kit is not a veterinary product and is not approved for any veterinary purpose, so it must not be given to pets or any other animal.
For research purposes only. Not for human consumption. Animal health questions belong with a licensed veterinarian.
Laboratory animal research, where it occurs, is governed by institutional ethics and regulatory review, and the batch COA is the reference for the material used.
