peptides

I've heard you talk on sermorelin and bpc 157. Could you talk more on peptides in general and maybe why bpc157 isn't more popular. My 55 year old mom just had a minor surgery, why wouldn't she get bpc157 to speed up the healing process? Is it just a cost thing? When I heard you speak on sermorelin I didn't really hear a drawback other than needing a prescription and possible speeding up tumor growth(but not likelihood of developing a tumor, right?) I understand you're taking it 3-5 days a week. TRT seems to be going pretty mainstream, is this even lower risk/downside and do you expect it to go even more mainstream? Any other peptides to think about or look out for?

Potassium and Kidney failure

In CKD at a late stage potassium levels start to rise. Is Resveratrol helpful or can it increase potassium levels in the blood?

Bipolar

I am 47 years old, diagnosed as bipolar for about 5 years. I experienced two bouts of depression the last two years ago, I am resistant to medication and have started treatment with trt by daily injection. The depression ended after two weeks of treatment, I have never experienced such stability in my life, do you know anything about the subject?

Physique and general health

To what degree is physique an indicator of general health? I have a friend who has quite poor nutritional habits - e.g. a very large proportion of his diet is highly-processed foods. He is an avid rock climber, so he stays pretty active, but no dedicated resistance training or cardio. However, he has the most impressive physique of anyone I know - i.e. good muscle mass, extremely low body fat, etc. I try to talk to him about the importance of exercise and nutrition (a lot of the things I learn from the podcast), but he doesn't take it seriously, largely because of his physique. So is his physique a good indicator of his overall health? Or is he at risk of particular health issues that don't surface in his physique?

Does cold weather really make you sick?

As I've been doing more deliberate cold water exposure, I've also wondered about the benefits of cold weather exposure - i.e. not wearing a jacket when I'm out and about in the cold. Similarly, I've wondered if I really need to bundle up my young children to go play outside if there are benefits to cold exposure. However, there's a pretty common understanding that cold weather can make you sick. Is this true, or just an old wives' tale?
