Which ones did you get?
To be general, an amulet is any object (usually a necklace) that has been charged with a specific energy.
So many people make the mistakes between talismans, pendants, amulets, etc. Amulets are nearly always for protection/strength, talismans are for luck, and pendants are any loose necklace with a charm or crystal attatched by a loop.
If your amulet is just for strengthening, cleanse it and then 'program' it to be for both protection and strength through a ritual, spell, whatever you like.
