Acetyl L-Carnitine

One ingredient, and that is the entire point. EHPlabs' Acetyl L-Carnitine is 100% pharmaceutical-grade acetyl L-carnitine powder: no stimulants, no sugar, no carbohydrate, no fillers and no flavour system.

Acetyl L-carnitine is the acetylated form of L-carnitine, an amino-acid derivative the body uses in fatty-acid metabolism. It turns up inside plenty of pre-workout and thermogenic formulas — EHPlabs' own OxyShred among them — which is the practical argument for buying it unflavoured on its own rather than paying for it twice inside something else.

A scoop is 1 g and the 100 g tub runs to 100 serves. EHPlabs' directions are one to two scoops in 295 ml of water, juice or whatever you are already drinking, and no more than five scoops a day. Because it is unflavoured it disappears into a shake without changing it.
