@Ecstatic_Hamster Do you mean you tested on yourself or had a lab test for thyroglobulin? If on yourself did you feel anything? I've tried cynomel+a generic t4 and it felt very different to any of these ndt products

Sites like lifegivingstore sell NDT thyroid but it's hard to trust if it actually contains thyroid. Has anyone considered having it tested for thyroglobulin to get a gauge of the amount of thyroid in the product(if any at all)?

I was looking at Ray's before and after with pregnenolone and notice that my skin is pigmented and creasing more.

Are topicals worthwhile? And what have you guys noticed the biggest difference with to stay looking youthful?
