Supplementation schedule?

I have an 8-month-old leopard gecko. I currently have Zoo Med Calcium with d3 and Zoo Med Calcium without d3. I also have herptevite by Rep-Cal. I feed 4 times a week. I feed only one type of insect per feeding. So here are how many insects I feed him per feeding. So if I feed him an insect, this is how much I feed him.

- 6 Silkworms
- 10 mealworms
- 8 crickets
- 6 Superworms

I leave calcium without d3 in his tank. I just need help on how to supplement him with the supplements I have now. Also is there any other supplement I can buy instead of my current supplements to make it easier? Also, how would I feed and supplement him when he is 1-year-old? Thankyou

I use Repashy Caclium Plus, it's everything they need in one to reduce the hassle of a schedule. I would dust once or twice a week with calcium+d3 and once a week with the multivitamin, unless someone else has another frequency of dusting input.
