Below you will see that twenty years of research have given us abundant ways to boost testosterone. I would guess many of the things on this list will surprise you: they are the opposite of what most of the bodybuilding magazines and health food stores will tell you.
One caution that I have is that I tried for years to raise my testosterone through lifestyle changes, i.e. diet, sleep, supplements, etc., and nothing budged my testosterone. And I see this quite often on The Peak Testosterone Forum: some men seem to have actual damage to some part of their HPT (hypothalamus, pituitary and testes) axis. In those cases, going natural just does not work for reasons that we do no understand yet. Of course, it does not hurt to try, and I especially encourage the younger men to do that.
- Sex. I get to be the bearer of good news: you can actually increase your testosterone levels by having sex. Let me repeat that again in case you needed some time to pick yourself up off the floor: you can boost testosterone by having sex. And you can also have a lot of fun while you’re at it. For more information, read this link on Sex and Testosterone. (Actually, I know that some of you need some practical ideas for how to get more sex from the woman in your life. Well, it’s not as hard as you might think in most cases. Here are a few ideas that will definitely help: Oxytocin, Massage, Tease Her and Increase Her Libido.)
- Sleep. I’ve got bad news for all you night owls: testosterone is directly related to the amount of sleep you get each night. The more sleep, the more you increase your testosterone. Sleep also boosts Growth Hormone and rebuilds your Brain. Want an easy way to increase your testosterone? Turn off the TV and computer and go to bed! For more information on the MANY benefits of sleep, read this link.
- Big Three. I give a summary of the Top Three Ways to Improve Your Testosterone Levels to find out the three natural ways that most guys can give a very substantial boost to their testosterone.
- Decrease Estradiol. Don’t underestimate the power of lowering your Estradiol in order to raise your testosterone. In this link on How to Lower Your Estradiol I talk about natural ways to do so. The effects of decreasing your testosterone were shown by one study of hypogonadal (low testosterone) senior men found that giving an aromatase inhibitor (Arimidex) raised testosterone on average by 62%.  This is a very impressive number indeed. Why? Because some males actually get osteoporosis from low estradiol levels. Furthermore, some estradiol is important for brain health. Still other 55 year olds have more estradiol than their wives! So each case is different and I recommend that you work with someone who knows what he or she is doing.
- DHEA + HIIT (middle-aged). There is an exciting new study out that shows that a combination of HIIT and 50 mg of DHEA produced very significant changes in both total testosterone and free testosterone. Participants basically performed (in the morning on an empty stomach) 5 cycles of very intense 2 minute cycling with a one minute rest in between.  So this would not be a walk in the park, but the results were downright incredible: the middle-aged (49-year-olds) boosted free testosterone by about 66 and ~90 percent 24 hours later. This is only one study and they did not pull estradiol levels. DHEA reportedly can sometimes raise estradiol levels and PSA levels in males disproportionately, although there are sublingual and topical forms that probably avoid these concerns. Regardless, it is always be smart in my opinion to pull your testosterone and estradiol levels before and after. You can find inexpensive labs to do this here: Testosterone Testing Labs.
- LDN (Low Dose Naltrexone). Might there be a huge inflammation connection to low testosterone? Well, why not since inflammation seems to be connected to almost every other condition and syndrome? We had one poster who took low dose Naltrexone (3 mg/day) and had stunning results: his thyroid antibodies dropped by 80% and his testosterone more than doubled!  It went from 400 ng/dl to 1,000 ng/dl, which is an incredible increase. Again, this is a specialized case, i.e. a man with Hashimoto’s and near hypogonadism. However, this situation is probably more common than many people think. Now, if you are fond of using a pharmaceutical even at a low dosage, there are many anti-inflammatory herbs and supplements that may also produce great results including turmeric, quercetin, red tart cherry extract and bromelain. Also, I should mention that LDN has had stellar results with numerous auto-immune conditions and is a very hot topic in the alternative health community. Again, though, I don t know of any solid evidence that this works consistently. (See my page on Naltrexone and Testosterone / E.D.)
- D-Aspartic Acid. This amino acid is in many off the shelf T boosters. Already one study on 23 young males found a 33% increase in testosterone (and Luteinizing Hormone).  A previous study on rats also showed an increase in growth hormone as well.  Not bad for a single amino acid, eh? However, the problem is that this is a relatively “new” supplement and long term usage history is scarce at best. In addition, amino acids can have rather profound effects, and so caution is in order here. For example, one issue discovered with D-Aspartic Acid is that it increases aromatization (to estradiol – E2) according to a couple of studies.  No one knows how much of an issue this is: some men are reporting estrogen-esque effects, particularly psychological.
- Diet. You can actually increase testosterone through diet. Read these links on Fat and Fiber and the High Testosterone Diet for more details.
- Weight Lifting. There is considerable evidence that long term Weight Lifting and strength training can actually increase baseline testosterone. Scientists aren’t really sure how it does this, but then does it really matter? The important thing is that pumping iron pumps up your hormones. CAUTION: Be careful, O Iron Warrior, not to Overtrain which will whack your hormones for days afterward!
