“I've felt sharper and able to perform mentally at a higher level for longer”

“considering I don't live in a country with very great control over stuff like adulterants”

“Creatine is known to increase DHT, and higher levels of DHT is linked to hair loss.”

“There was actually a VERY recent study on mega-dose creatine for sleep deprivation”

“Significant physical changes! But other than the pure aesthetics, it's hard to say that my strength increases are tied to creatine”

“Either of those companies should address the concern around adulterated powder.”

“There is a brand of creatine manufactured in the US (con-cret)”

“I experienced dramatic and obvious hair loss in my late twenties after starting creatine supplementation.”

“I can keep on track for a significantly longer time since ive started supplementing with it”

“I have noticed a lot less cognitive impairment after a poor night's sleep since starting on 10g per day.”

“creatine has been proven to be completely harmless for people of all ages”

“It is one of the most studied substances and except in special cases like kidney issues it is totally safe.”

“it's one of the few thing that helps strength, poses no danger to your hair”

“it does seem to help a bit with my (more than occasional) sleep deprivation”

“I can't stop having vivid, and mostly bad dreams with it making me tired the next day.”

“those extra reps and slightly more weight have compounding effects over time”

“it is proven to work for athletic performance and second, it's relatively safe”

“Gummies and many gym focused powders are extremely overpriced. Buying in bulk you should be able to get it for ~$.15 a day at 5g.”

“a noticeable improvement, especially during busy/sleep minimizing times”

“In terms of optimizing overall health I would say take it + running + strength training is a good combination.”

“research seems to indicate it's a net positive with a small effect and it seems very safe”

“basically only three things with any body of evidence that they work with few/any downsides”

“I’ve gone through two periods where I took it and liked the effects, but felt like I shed way more hair and stopped due to that.”

“I had a lot of issues with stomach when taking creatine until I tried the micronised version. Bucked up makes a good product you can find at Walmart.”

“If I take creatine too late in the day, it definitely wrecks my sleep.”

“ended up with a level of diarrhea that I’ve previously never encountered without being sick”

“Creatine helps. It gets stored in the brain as phosphocreatine, which can be used via creatinease to build ATP faster from ADP.”

“your creatine stores will be at a level where you'd probably only see a cognitive benefit at times of sleep deprivation”

“I found it insanely helpful for maintaining a sharp mind throughout a long day”

“Creatine monohydrate (and seemingly HCL too, though not tested long term) kind of makes me constipated.”

“Creatine is the closest the supplements industry has ever gotten to actually producing something that helps people.”
