I am trying out damina leaves. 1.02 grams three pills a day

It seems to make my testes bigger.

I am also taking all of these twice a day:

ProtoTrib tribulus 50 mgrams
L-arginine 250 mg
L- citrulline 150 mg
LJ100 Tongkat ali 75 mg
Oat straw extract 200mg

Does any one see any dangers that may arrive from these supplements?
