Same. Started daily creatine age 13-14, have taken it daily (5-15 grams) since. Rare breaks like elk hunting for 2 weeks every fall, illness, travel, etc.
I’m always a little unnerved when doctors can’t think around the TRANSIENT incidental lab findings that “tell” them something bad is going on with the kidneys. I had to literally tell my doctor -once-exactly why my renal panel looked like a bag of dicks on a certain day with specific training behind me and why it would be normal tomorrow.
I told him “I will NOT do those specific things and I will, of course, repeat the labs”. Next panel=perfection. But I had to walk him through the physiology.
I won’t give a lecture here on subtleties of lab interpretation in the wild. The scary thing is new or just frankly subpar practitioners throw out awful advice all the time based on gross misunderstanding of labs.
And that’s likely NOT new information. To anyone.
