The dosage is dead on.
My vet if i need anything i just call up and i get the Rx. Dosages re given and ill write them down.
The way to figure out dosages is this.
Snakes weight in LBS x .45= weight in KG then Divide by4 and you get your dosate in CC.
so your one snake of 845g ill use as an example.
845 in lbs is 1.86lbs
1.86lbs x .45=.837kg divided by 4 = .209cc. Which is transferred to 2ML per dosage
