Market in the US does not exist.
I imagine you have no market either.
Very quick Google of Russian market; first hit of many; the price in Rubles (convert as needed; of course, the prices are appropriate for their level)
If any decent scale, the beeks sell the raw larvae juice (frozen - a must) to the retail product manufacturers.
Now days some people started drying the "juice" in special equipment (can be pricey; essentially lab grade - but if going up scale, should pay off).
Similar in Ukraine:

The beeks should be looking ahead and developing the larvae juice, bee bread and the like food supplement markets with appropriate prices.
Not sitting on the honey wagon, like we are in 19th century of sorts.
PS: I like the term you called it - the drone larva juice; works for me.
