The (R)-enantiomer of carnitine, supplied as a solution
Research topic: Body & metabolism · group: Lipid metabolism and auxiliaries
L-Carnitine is the (R)-enantiomer of carnitine, the physiological form: a small, highly polar zwitterion that takes part in the carnitine shuttle, which moves long-chain acyl groups into mitochondria. Our product table lists it as a solution in vials — by amount per vial, or by volume — in kits of ten. The same molecule, as levocarnitine, is the active ingredient of approved medicines; what we supply is research material, not a medicine. It sits with the auxiliary materials of our body-composition and metabolic page. The studies in our product data are biochemical: the mitochondrial carnitine–acylcarnitine translocase, carnitine acetyltransferase and carnitine transport in muscle.
Same molecule, not a medicine
As levocarnitine, the same molecule is the active ingredient of approved medicines. What we supply is research material in vials — the same molecule, but not a medicine.
Every lot of L-Carnitine has its own batch COA, which lists the tests run on that lot and their results.
Ask for the COA of the batch you are quoted; the batch number on it is the batch we ship.
Each picture is the first page at low resolution, with numbers, dates and signatures covered, so the small print cannot be read. The full, clear copy comes from sales — ask for it by product and strength.

What to put in your quote request
With these facts the first reply can carry the unit price per kit, shipping and lead time.
No. Acylcarnitines such as acetyl-L-carnitine, the D-enantiomer and salts such as the L-tartrate are different materials with different formulas. The fact table refers to free L-Carnitine.
Our product table lists most of the solutions by the amount of L-Carnitine per vial and one by fill volume. The quotation and the COA of the lot state the concentration.
One kit is 10 vials of the same product at the same strength. Each vial holds the stated amount, for example 10 mg of lyophilized peptide; the few solutions are stated per vial in mg or ml. 1 kit per product and strength. One order can combine several products and strengths, each from 1 kit.
Every lot has its own batch COA listing the tests run on that lot and their results, with the lot number of the vials you receive. Yes. Ask for the COA of the batch you are quoted; the batch number on that COA is the batch we ship.
In writing, per request. Prices are tiered by the number of kits of each peptide and strength; the quotation gives the unit price per kit, the shipping cost and the lead time. We reply within 24 hours.
Because listings describe different forms: a free peptide or a salt (acetate, TFA), a copper complex or its free peptide, one peptide or a two-peptide material — and some registries keep older numbers. Each product page says which form its values refer to; the COA of the lot is the reference.
