“Many health food stores are now selling melatonin, to induce sleep and “prevent cancer.” They have taken some information out of context, and don’t realize how dangerous melatonin is. It makes the brain sluggish, causes the sex organs to shrink, and damages immunity by shrinking the thymus gland. It is the hormone of darkness and winter, and is produced in the pineal gland by any stress which increases adrenalin. Adequate sun light suppresses the formation of melatonin.” -Ray Peat, PhD
"In general, the direct actions of melatonin on the gonads and adnexa of mammals indicate it is an important agent for maintaining optimal reproductive physiology"

When I look at other papers in this space I do find some adverse responses in hamster nuts when given melatonin injections (but not when it is administered using an implant).
At this point I did not want to research the other claims in the quote anymore. Instead, perhaps I can ask you: Do you know of any solid research that backs these (frankly very strong and contrary to everything else I've read) claims? If not, why did you choose to say this?
