Retinax AM (latterly called EPX2*) is actually a Lithium-soap thickened grease (nearly all commercial greases are), it's the addition of MoS2 solid lubricant which makes it better than lithium greases without EP additives.
* and they've renamed everything again. Of the current Shell range, I'd pick Gadus S2 V220AD as it has the MoS2 and it is Lithium/Calcium thickened, which is more water resistant than plain lithium. Buy online ~£6 for 400g.
The MoS2.
