Can you recommend a less costly but potent glutathione brand? Have you heard of its adverse effects? What about the lead content in magic creams? What are its adverse effects?

How many weeks before you will knotice the efec of l-glutathione-500

There are many cheap brands coming out in the market. And I've known some who use it but for months now, I can hardly see results in them. I suggest that if you really want something that works go for known brands sold in reputable drugstores, only a lot more expensive.
