glutathione capsules vs. glutathione injectables

Glutathione intake is already doubtful what more if it were injectables? am I right?

glutathione nowadays is acceptable, as many explains it effect in us. a powerful anti oxidant, and a whitener, but i guess the capsule is more safer. i think the injectables dosage is so high and that it is directly injected to the veins, and i believe because of its higher dosage than the capsules, skin whitening take effects even just for a few sessions injecting it. though the capsules claim you can achieve a so-white skin, you still need to take in orally a lot of it. and you cant expect it to whiten you if you only want to take it for 1-2 months or even 6 months. but with injectables expect it, even just for 5-6times injecting it on you. injectables can promise you a white skin instantly, than the capsule ones but capsule ones is much safer than the injectables.. i guess!
