What is L-carnitine?
L-carnitine is made in the body from lysine and methionine. It carries long-chain fatty acids into mitochondria so they can be burned for energy.
Most dietary carnitine comes from meat.

L-carnitine in published research
Clinical work covers carnitine deficiency and kidney disease. Studies in athletes are mixed.
In the lab it’s a standard tool for studying fat metabolism.
You can find the papers on PubMed. We don’t make claims beyond what that literature reports.
Reconstituting L-carnitine for research
The vial holds L-carnitine as a dry, freeze-dried cake. To use it, dissolve it in bacteriostatic water, letting it run slowly down the side of the glass so it doesn’t hit the powder directly. Swirl or roll the vial until it’s clear. Shaking can damage peptides, so skip it.
The amount of water you add sets the concentration. For example, adding 2mL of bacteriostatic water to a 500mg vial gives 250mg per mL. Write the volume and the date on the label so anyone picking up the vial later knows what’s in it.
We sell bacteriostatic water in 30mL vials, and acetic acid solution for the few peptides that don’t dissolve well in water.
L-carnitine quality and testing
We test each batch of L-carnitine by LC-MS, which pairs liquid chromatography with mass spectrometry. The chromatography splits the sample into its components and the mass spectrometer identifies them, which tells you both identity and purity. This batch came in at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storing your L-carnitine
Keep it in the fridge at 2 to 8°C and don’t freeze it. Once mixed, keep the vial in the fridge and use it within a few weeks. Unmixed vials keep much longer, so only reconstitute what you need. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
Common questions about the L-carnitine vial
Does L-carnitine come with water to mix it?
No. The vial holds only the freeze-dried powder. Add bacteriostatic water to your order if you don’t already have some.
How long does mixed L-carnitine last?
Kept in the fridge, most reconstituted peptides are good for a few weeks. Unmixed vials last much longer, especially in the fridge or freezer.
Is the L-carnitine vial in stock?
Yes. Every option on this page is in stock and ready to ship.
