How long can leo last without supplements?

[Hotpeon]

It's been a week since my gecko's eaten anything powdered (he's shed on 28th) and everytime I come to feed him since he doesn't seem interested in food and only wants to climb and sploot on my arm. I'm letting in some dubia after and he usually hunts most of them down but I'm afraid that the powder already washes off until he catches them. Today I've put a cup full of mealworms covered with multivitamins powder and hopefully he gets them before they escape since he again showed no interest into eating them wriggling on the floor nor in the cup. He also has a calcium dish inside of his enclosure but he doesn't seem to use it. I was not worried at first as he just started to trust me to hold him but now I see him glass surfing whenever he notices me and then he insists to climb on me. It doesn't seem like he wants to run away since he's only sleeping on my hand, the temperatures are in order and he's pooping fine. Hopefully it's just another irrelevant scare he's given me but I just want to make sure he can be fine even if he's not getting powdered food.

Edit: He only eats food he can hunt, he never eats from tweezers or hand even though he's not afraid of either. Would he grab it if he was hungry, as I've seen other leos do?

They can probably go quite awhile (months at least) without supplements, which is not to say that it's best to only supplement once every few months. If you really feel your gecko isn't getting any supplement, you could dip your finger in water, then dip it in the supplement and spread some of the resulting paste on its lips. It will likely lick off the supplement. I would do this only every few weeks.
