Venom Potency?

[ReignofInvertebrates]

Looking for some lower-end Buthids to add to my collection. Does anyone know how bad the venom is of the following?

-Uroplectes otjimbiguenses
-Heteroctenus junceus

 

[ArachnoDrew]

They're not considered deadly
Junceus venom in more recent years has been used in cancer research but I personally know a small few people who have been tagged with no real issues
