Expert Opinions from Ophthalmologists on Iris Alteration Ophthalmologists say changing iris color is risky

Its been clinically studied since 1973 (and there are tons of medical journals you can read on it) but everything I am saying is considered alleged and supposed because there isnt FDA-approved evidence for these claims

Not sure what scientific backing they have for most of the claims made on their 'learn more' page - most of which looks biased at best - and really not sure where the claim that you will lose the effect of the shot more quickly if you drink more water comes from - never come across any studies that would imply that was true - it also claims that B12 isn't stored in the body and because it is water soluble which is definitely a load of twaddle
