Legal Notice: Yes, you can do studies

Medical professionals

I've talked before about HOW you might legally check my hypotheses as a medical professional and not get yourself in trouble that could cost you your medical license. 

Ideally, you cite your sources including listing this site as the source of the idea that led to a study. If you aren't stealing my ideas and pretending you came up with it, I have zero problem with you extending my work and give me credit for my part and then take credit for doing the study.

Individuals 

Individuals aren't legally required to get permission to do whatever whackadoodle thing they wish to do to themselves.

I've repeatedly linked to a post on how to check my hypotheses SAFELY as an individual.

From Safety Concerns:

I will NOT be the one trying to run a discussion forum or other means to crowd source this information. I have a conflict of interest.

The trans community should check it for themselves and determine if this actually works or not. This will only ever become a viable alternative IF it's a grass roots movement by the people involved who trust EACH OTHER.

Or alternately the MEDICAL community does studies and publishes them and links to this site as the original source.
