Good post and interesting facts, as a creatine user myself will be keeping a close watch!
Creatine Increases Dihydrotestosterone (DHT): Is Creatine Bad For Your Health?
December 18 2009
Is creatine bad for your health? The recent study shows an increase in DHT (dihydrotestosterone) as one of the side effects of creatine and raises some interesting questions about the safety of long-term creatine use.
What is DHT & is it Harmful?
DHT (dihydrotestosterone) is male hormone formed in the hair follicles, testes, prostate and adrenal glands.
Apart from the benefits, DHT is a contributing factor for male pattern baldness and plays a key role in Benign prostate hypertrophy.
Prostate cancer is strongly linked to male hormones, and recently DHT has been associated (not causative) with prostate cancer.
What was the creatine & DHT study design?
The study was well designed to minimize biases and errors.
Double Blinded: The study was double blinded and hence the researchers and the subjects did not know if they were getting creatine or placebo.
Cross over design: As shown in the pic, the study used a cross over design so that every subject receives both creatine and placebo, thereby minimizing the errors and the need for a large group of subjects.
Groups: Subjects loaded with creatine (25 g/day creatine with 25 g/day glucose) or placebo (50 g/day glucose) for 7 days followed by 14 days of maintenance (5 g/day creatine)
What were the results of the creatine & DHT study?
The major findings of the study were:
DHT: The levels of DHT increased by 56% after 7 days of creatine loading and remained 40% above baseline after 14 days maintenance (significant)
Ratio of DHT to T: The ratio of DHT:T also increased by 36% after 7 days creatine supplementation and remained elevated by 22% after the maintenance dose.
The ratio tells us that the increased DHT levels are not because of a higher testosterone levels but a greater conversion of T to DHT.
So is creatine bad for your health?
- Bad News: For the first time, the study shows a significant increase in DHT levels (at loading & maintanance phase), and as mentioned above DHT is contributing factor for male pattern baldness and is associated with prostrate cancer.
- Almost all the studies done on the safety of creatine were short term. Only a handful of long-term studies exist and they only lasted for a year. So the long-term safety of consuming creatine for 5-10 years is still not conclusive.
- Good News: There has been a number of studies in humans showing creatine has no adverse effects, barring the gastric upset in a few folks.
- People have been using creatine for years and we haven’t heard much about people losing hair and getting prostate cancer.
- A high DHT to testosterone ratio do not always mean that you will get prostate cancer. Like all cancers, the cause of prostate cancer is multi factorial and cannot be pinned down to one factor.
- In research, controversial findings like these need to be replicated in other labs before it can be taken seriously.

Hi BR,
Thanks for the correction. Changed it.
Iam really worry,i do take creatine with dextrose and vitamin c and antoxyforte cap,should i discontinue?
I’ll contribute my $.02.
I started taking creatine in the spring of 2006.
By next summer, my wife noticed my hair was thinning at the crown of my head.
By 2009 my hairline had moved back about 1/2 inch.
I had googled Creatine-and-hairloss several times during the course of these 3 years and despite hearing from many ‘experts’ that creatine has no effect on hair loss, I read dozens upon dozens of personal stories who contradicted this.
In fact, one hair-doctor posted a number of emails from people asking if creatine killed hair. This doctor remarked that he got these letters all the time.
Since quitting in 2009 my hairline and thinning on the crown have appeared to stop. In fact, my hair is thicker now than it was a year ago. My barber even started using thinning shears again.
But just to make sure my imagination wasn’t playing a trick on me I went through many photo’s and videos of myself from 2000 until 2006 to see if my hairline was naturally receding.
I showed pictures of myself during that time frame and tried to have my wife guess what year it was from. She never got it right. In fact, in photo’s where I was 33 (before Creatine) she routinely guessed thought I was in my 20’s. My hairline was the exact same for over half-a-decade.
But when I showed her photo’s of my hair from 2007 and 2008 (after a year or more of Creatine) it was night-and-day. She hadn’t realized it because she lived with me. And my friends noticed it too.
And the kicker? Not one male on either side of my family has any hair loss. Both my grandfathers, well into their 80’s, have hair John Stamos would be jealous of.
The same goes for my father, my brothers and uncles and cousins on both sides of the family. We look like a large group of Baldwin’s for crying out loud.
So that’s why I knew genetics weren’t playing a mean trick on me.
I’ve started taking Saw Palmeto and a multi-vitamins (Vitamin B and E) to help lessen the affects that creatine ravaged on my hair but it’s disappointing that I sacrificed a great hairline for more muscle. So while I was making one part of me look better, I hampered my appearance from the neck up.
I’m just happy I caught it before I did major damage. The thinning in my crown isn’t noticeable unless I’m under intense light and my hair is wet. But my hairline took a beating and can’t be ignored by most. It just sucks that I’ll have to live with that the rest of my life.
I hope others read this and don’t fall into the same mistake I did.
Stay away from creatine. It’s not worth it.
It’s a quick fix for extra muscle. But if you do it right (like I am now) by eating healthier and consuming more natural foods filled with protein, not only will you look great, but you’ll be naturally bigger too. Win-win.
Buddy iam taking creatine for the last 1 year but mine hair is still intact,no side effects of hair loss.
So,
1. Creatine is not for everyone.
2. Some people are negatively affected by DHT; some people are not.

Hi Sirdon,
It is still inconclusive about creatine and DHT. We need more studies and I am sure we will see one soon.
Hi Steve,
Creatine and weight training seems to significantly increase DHT in short term. We do not know this will happen in long term. We do not know if this short term increase in DHT can cause hair loss or prostate cancer.
Thanks for the comments guys.

i am truly sorry to hear about your prostate cancer, however why would anyon want to take creatine for more than a year straight.any supplement no matter how safe, always has damaging long term effects. ex… vitamins are supposed to supplement our diet, but when taken over a long period of time they will store excess of any natural substance in your body and cause negative effects in your body. everything should be taken in intervals or cycles so that your body has an opportunity to refresh or clean itself.

The people that go bald have a less chance of getting prostate cancer, and the people that don’t go bald have a higher chance of prostate cancer. It was on the news about 3 months ago on a find about balding and prostate cancer.. Im 20 and have a receding hairline. My dad is balding and my grandpa was fully top head bald at 21.. So of course im gunna be bald.. hahaha
I have heard about all this DHT stuff lately because I am losing some hair all of a sudden. I am thinking of eating much more healthy organic food instead of any shakes. Also, have you heard about DHT production with frequency of ejaculation? I was wondering if any good clinical studies have been done for that.
It seems more speculation at this point that sex=DHT…It’s very weird if nobody has performed a proper clinical study to test the link between the two.
Anoop | Mon January 17, 2011
Hi JJ,
I am aware of no studies which looked at this issue. I don’t think there is a link considering there is no biological link between ejaculation/sperm and DHT.
Just make sure you guys don’t try to reduce your dht levels too much, trust me DHT is a very useful and misunderstood hormone. DHT is absolutely essential for libido, erection quality and being able to blow more than one load a day. DHT blockers have messed with my sex life so bad, I think i’m gona try creatine and a heavy workout routine and see if this will raise my DHT levels so I can function again.

Hi Louis,
Thanks for the comment.
I think what you need is an endocrinoligist instead of creatine.
Anoop | Sun February 27, 2011
Hi Louis
There are are pharmacological agents that can raise DHT levels. But, more importantly, they need to make sure you indeed have low levels and why you have those levels.
I would be very wary messing with all these hormones. It is better to leave those to people who know about it.
I agree however doctors in canada seem to tell me I have nothing more than psychological problems. Its very fristrating. That’s why I’m going to the mayo clinic in phoenix in a couple weeks. Hopefullu they can undoe this mess accutane got me into

Hi Juarez,
I haven’t seen any and I just checked. Why? Are you losing hair (:-
So I started working out hard and taking supplements about a 2 years ago. I’ve began to notice my hair thinin quite a lot. My question is If I top taking supplements will my DHT levels go back to how they were before? Or after they are raised they remain high? Any suggestions?
I, like Jim@TBF took EAS Phosphagen at a young age, however I lost a lot of hair while taking it (in my early/mid 20’s). Subsequently after discontinuing use, my hair loss stopped. I loved the results that I got from CM, but I could tell something was making my hair fall out excessively at an early age. Now, at the age of 38, I have decent hair but maintain the same hairline. I believe this study whole-heartedly. I haven’t touched Creatine since, and I feel like that has saved my remaining hair.
I took CM for about a year. Some hairline issues that my wife noticed over time, and I thought was just aging, but no baldness in my family either. The bigger issue was that I ended up in the hospital for six days with what seemed like heart issues/palpitations. Turned out my magnesium level had dropped severely due to renal issues. Now I have to take magnesium supplements every day, as my kidneys do not maintain proper levels. A contributing factor may have been regular use of whey protein powder, which is also hard on the kidneys. Regardless, I’m off CM and will never go there again. My advice: Stay away from it. Short-term “benefits” are not worth the long-term risks. Eat healthy and work hard, and let your body develop to the levels it is designed to.
This article makes a poor assumption that dht is bad.
Dht is a critical hormone in masculinity and what makes you a man.
It is the sole hormone in what gives you chest hair penis growth and general masculinization.
Just check out what happens to baby boys that are missing 5alpha reductace, which is what converts test to Dht.
Dht is a very good thing.
I would say to the guys trying to lower Dht be careful. Ful head of half but no sex drive, I wouldnt find pleasent.

The emphasis of this post so far has centered around the potential negative effects of DHT. Whether elevated DHT levels are associated with various risks and side effects is an ongoing question. Even among serious bodybuilders, DHT is often tagged as an undesirable metabolite of testosterone; hence the use of 5-alpha reductase inhibitors, such as finasteride, by those who inject testosterone in supraphysiologic quantities for the augmentation of muscle mass and strength.
It is worth considering, though, that the purported elevations in DHT that result from supplemental creatine use may be more than simply “side effects” and may actually contribute to creatine’s well-documented anabolic and strength-building effects. Relatively recent research suggests that DHT may indeed have anabolic and strength-building qualities—albeit non-genomic (i.e., that do not manifest themselves by virtue of androgen receptor binding on muscle tissue).
Briefly, recent literature suggests that:
1) DHT, unlike Testosterone, may lead to an enhancement of force production in fast-twitch skeletal muscle fibers (“Dihydrotestosterone activates the MAPK pathway and modulates maximum isometric force through the EGF receptor in isolated intact mouse skeletal muscle fibres”)
2) DHT, unlike Testosterone, stimulates amino acid uptake into fast-twitch skeletal muscle fibers (“Dihydrotestosterone stimulates amino acid uptake and the expression of LAT2 in mouse skeletal muscle fibres through an ERK1/2-dependent mechanism”)
It’s beyond my level of knowledge or expertise to speculate further on how the significant elevations in serum DHT that purportedly take place with creatine use according to the discussed study might produce the non-genomic DHT effects suggested above, but the aforementioned research suggests some possible mechanisms by which creatine may exert its well-documented anabolic and strength-building effects. At the very least, these studies may provide us with a stimulus to rethink the negative associations many of us have with this hormone.
I find this very interesting. I was supplementing with CM for about 4 years as a 25 year old. I had massive gains in terms of muscle, but i did notice my hair shedding as i cycled the supplement. I took a blood test to see my DHT levels, they were about 30% above ” normal “.
I for a short time used propecia to regulate my DHT. It rectified the problem I then moved to a herbal method which works great got rectify the long term issue of regulating my DHT. (Saw palmento). Don’t stay on Propecia too long, its not worth the damage it does to your hormones.
I also used a topical chemical called aminexil to clear my follicle damage. This removed the DHT sebum, most underrated hair product out there.
I however missed the muscle gains I was getting on creatine Mono, so i started again, once again same spike in DHT levels, so I had to stop. Same with my best mate, this actually caused him prostate issues.I spose everyone’s body is different, but i know of at least 2 cases ( mine and my best friends ) where creatine boosted DHT through the roof. Its a real shame because it was an awsum supplement and i put on massive gains with it.
thanks for the post. Very good.
Hi Anoop! I can´t find the answer to this in the study but could one expect that the DHT levels returned completely to the “before levels” during the 6 week wash out period?
Which, in the context of hair loss, would mean that one should not experience any accelerated hair loss after discontinuing creatine? The effect one DHT is just temporary?
Thanks for the post.

Creatine is a great supplement, its been extensively tested over a long period, as a supplement on atheletes and it has shown great results. This new information is quite interesting and deserves further investigation, thanks for the great article.
