A couple of years again, PN co-founder John Berardi, PhD, posted a shirtless picture of himself on his forty seventh birthday.
He known as it his “anti-regress pic” and thanked 30 years of squats, deadlifts, presses, and chin-ups—amongst different workouts—for his chiseled six-pack, pumped chest, and bulging biceps.
The query many commenters posed:
“Are you on testosterone?”
Dr. Berardi defined in a follow-up submit that whereas he wasn’t towards testosterone substitute remedy (TRT) for individuals who wanted it, he himself was not on this remedy, and his testosterone ranges have been boringly “regular.” He additionally supplied some thought-provoking concepts about testosterone and getting old.
- The mainstream opinion appears to be that declining testosterone is a harbinger of getting old, frailty, and impotence—to not point out a risk to masculinity.
- Growing numbers of middle-aged males are ditching conventional medical checkups for males’s-focused telehealth clinics focusing on testosterone enhancement.1

Whether or not you’re a coach who fields the “How do I optimize testosterone?” query from shoppers—or only a common dude hoping to age properly—it’s straightforward to really feel overwhelmed and confused by the conflicting info.
Are declining testosterone ranges regular?
Do testosterone-boosting complement regimens truly work?
Who advantages from testosterone remedy—and who doesn’t?
On this story, we’ll discover these questions and extra.
What’s testosterone?
Secreted by the testes, testosterone is the intercourse hormone accountable for male sexual traits akin to large muscle tissue, deep voices, and furry chests. It’s a chemical messenger that performs a key function in numerous processes all through the physique, together with sperm manufacturing and bone density.
(In girls, who additionally want testosterone to maintain numerous processes buzzing, testosterone is secreted by the ovaries and adrenal glands. Their our bodies simply make a lot much less of it; about 10 to twenty instances lower than males.)
Presumably due to its relationship with muscle progress and intercourse drive, a variety of cisgender males consider testosterone in binary phrases, with decrease testosterone being dangerous and better testosterone being good.
Nevertheless, it’s extra correct to think about the connection between testosterone and well being as a continuum that goes from too low (problematic) to too excessive (additionally problematic), with the wholesome vary falling between the 2 extremes, says Denise Asafu-Adjei, MD, MPH, urologist, males’s well being knowledgeable, and assistant professor of urology at Loyola College Chicago-Stritch College of Medication.
Because the chart beneath reveals, the hazards of extraordinarily low testosterone are just like the dangers of extraordinarily excessive quantities (usually solely achievable with using anabolic steroids).

Low testosterone vs. decrease testosterone
Testosterone ranges naturally ebb with age, with most males dropping about 1 to 2 % yearly beginning round age 40. By age 75, most males have 30 % much less of the hormone than they did at age 25.2
(Enjoyable reality: Between ages 25 and 80, males can anticipate their testicles to shrink 15 %.3)
Nevertheless, age-related drops in testosterone should not the identical factor as “low testosterone.”
Hypogonadism is the medical time period for low testosterone ranges, and it impacts about 35 % of males older than 45 and 30 to 50 % of males who’ve weight problems or kind 2 diabetes, in accordance with the Endocrine Society, one of many skilled public well being organizations that units hypogonadism therapy pointers.
Not solely can overly low testosterone make you’re feeling fatigued and do a critical quantity in your intercourse drive, however it may additionally hurt your bone and cardiovascular well being, says Dr. Asafu-Adjei.
“You want testosterone for good bone energy,” says Dr. Asafu-Adjei. “As you grow old, you’re already coping with weaker bones, so having lowered testosterone isn’t going to assist.”
Alternatively, bringing ranges as much as regular appears to supply cardiovascular advantages, she says. (The large caveat right here is as much as regular—not far above it.)
The significance of referring out
What if you happen to or your consumer have many of the hallmark signs of hypogonadism however nonetheless have blood ranges of testosterone within the regular vary?
“Many males over 30 who really feel down or low power will now mechanically blame their testosterone,” says Dr. Asafu-Adjei. “Their signs could be associated to testosterone, however in addition they could possibly be associated to not sleeping, stress, or another issue.”
That’s why seeing a healthcare skilled specializing in males’s well being and testosterone administration is so necessary.
Such a doctor can display screen you or your consumer for dozens of different issues (like stress and poor sleep) and situations (like diabetes, weight problems, or sleep apnea) that both mimic the signs of hypogonadism or intrude with the manufacturing or signaling of testosterone.
In different phrases, supplemental testosterone is the reply for some males with signs of hypogonadism, however not all of them. An in depth workup is required.
“There are overlapping signs with low testosterone in addition to a variety of nuances round hormone therapy,” says Dr. Asafu-Adjei.
“For instance, exterior of your complete testosterone, we additionally take a look at your testosterone-to-estrogen ratio and different associated hormones. That’s why it’s so necessary to go to somebody who is aware of what they’re doing. They’ll take a deeper dive to determine the basis of the issue.”
So, if you happen to specialise in teaching middle-aged and older males, get a urologist or endocrinologist in your referral community.

Testosterone and aggression
Many individuals assume that, in excessive quantities, testosterone turns males into pushy, road-rage-fueled jerks. Nevertheless, the affiliation between the hormone and habits is far more advanced.4
Because it seems, each an excessive amount of and too little testosterone can result in irritability.
As well as, the hyperlink between testosterone and aggression relies upon quite a bit on somebody’s character, upbringing, context, social norms, and extra.
For instance, in a single experiment, researchers requested forty younger males to play a online game that concerned accepting and rejecting presents from a proposer. If somebody deemed the proposal too low, they may reject the provide and punish the individual for making such a substandard ask. Alternatively, in the event that they thought-about the provide helpful, they may settle for it in addition to reward the individual.5
Researchers injected a number of the males with testosterone as they performed the sport.
As anticipated, gamers handled with the hormone have been extra prone to punish proposers, particularly in the event that they thought-about the provide unfair. Nevertheless, in the event that they perceived the provide as truthful, they rewarded the proposer extra generously.
The elevated testosterone amplified aggression, but additionally generosity.
Some researchers confer with this phenomenon as “the male warrior speculation,” which holds that testosterone could perform to assist some males shield and cooperate with their “in group” (akin to their household, mates, and coworkers) whereas concurrently punishing anybody seen as an outsider.6
7 evidence-based methods to optimize testosterone… naturally
On the Web, if you happen to search for methods to spice up testosterone via life-style, you’ll rapidly turn out to be inundated with complement suggestions and lists of T-boosting and T-harming meals.

So, while you chronically burn extra energy than you devour, hormone ranges typically drop. (That is true in each women and men.)
“Numerous males of their 20s and 30s come to me about their low testosterone ranges and their low testosterone signs,” says Dr. Berardi. “These are principally guys who prioritize train. They work out quite a bit and watch what they eat. In different phrases, they’re males experiencing mid- to long-term adverse power stability.”
Dr. Berardi’s recommendation is commonly not what males anticipate.
If their consuming and train routines recommend they’re in a continual adverse power scenario, he merely recommends they eat an additional wholesome snack or two a day.
“In conditions like this, including a pair hundred further energy of high-quality protein and carbohydrate usually fixes all the pieces,” he says.
These added energy might come from a pair scoops of whey protein combined in milk with a nut butter and banana sandwich on the aspect, he says.
One other favourite snack of Dr. Berardi’s: A bowl of steel-cut oats with protein powder, cacao powder, dates, uncooked nuts, and nut butter.
Take into accout: Consuming an excessive amount of (and gaining fats) may have an effect on testosterone, as we’ll cowl quickly. Use our FREE vitamin calculator to make sure you’re consuming the correct quantity of energy and vitamins to help hormone manufacturing.
Testosterone optimizer #2: Prioritize sleep.
Testosterone manufacturing has its personal circadian rhythm: It’s increased within the morning and decrease on the finish of the day.
As you sleep, ranges rise once more, peaking throughout your first section of speedy eye motion. This may increasingly clarify why numerous sleep issues—together with sleep apnea—are related to testosterone deficiency.7
A handful of small research have checked out what occurs to hormone ranges when males skimp on sleep.8 In one among these research, members slept simply 5 hours an evening for eight days, leading to a ten to fifteen % drop in daytime testosterone ranges. 9
The correct quantity of sleep varies from one individual to a different. Nevertheless, if you happen to routinely get fewer than seven hours and wake feeling exhausted, it’s wager you’re not getting sufficient. In the event you wake unrefreshed or battle to sleep soundly, our 14-day sleep plan can assist.
Testosterone optimizer #3: Preserve wholesome physique fats ranges.
Physique fats secretes aromatase, an enzyme that may convert some testosterone into estrogen.
In response to some analysis, males categorized as chubby or overweight are inclined to have barely increased ranges of estrogen, in addition to the stress hormone cortisol. 10 11
Extra analysis is required to know whether or not these barely increased estrogen ranges are sufficient to contribute to hypogonadism.
Within the meantime, nevertheless, a wholesome physique composition is important for general good well being and may additionally assist to optimize testosterone.
Take into accout, as we mentioned above, that too little physique fats may negatively have an effect on testosterone ranges. To make sure your physique fats ranges are within the optimum zone, use our FREE physique fats calculator.

Resistance coaching presents extra of a testosterone enhance than endurance train. (Two to 3 classes every week is a superb benchmark.)
Nevertheless, endurance train may assist, offering you train on the proper depth, finds analysis. (That’s half-hour of rigorous exercise, 4 to 5 instances every week.12)
Overtraining with out sufficient restoration can result in the alternative impact although, doubtlessly inflicting positive factors to plateau and suppressing testosterone.13
(See our FREE train library for 400+ knowledgeable how-to movies and a 14-day at-home exercise program.)
Testosterone optimizer #5: Eat a well-rounded, nutritious diet.
Along with serving to you keep away from nutrient deficiencies that may drive down testosterone ranges, a nutritious diet protects your blood vessels.
That’s essential for getting erections.
A examine of 21,469 males discovered that those that consumed meals according to the Mediterranean weight-reduction plan had a decrease danger of growing erectile dysfunction over ten years in comparison with males who didn’t observe the weight-reduction plan.14
“Mediterranean diets are additionally identified to advertise coronary heart well being,” says Dr. Asafu-Adjei.
The Mediterranean weight-reduction plan emphasizes fruit, greens, entire grains, nuts and legumes, and wholesome fat from meals like olive oil, eggs, and fatty fish. It de-emphasizes purple and processed meat, sugar-sweetened drinks, and sodium.
Nevertheless, consuming patterns that heart on minimally processed entire meals doubtless provide the identical advantages.
Many fruits, veggies, and different minimally processed entire meals are wealthy sources of flavonoids, a plant chemical that helps to enhance blood circulation and testosterone manufacturing.
(This visible consuming information can assist you select the very best meals on your physique.)
Testosterone optimizer #6: Keep away from continual emotional stress.
While you’re below stress, your physique produces cortisol and different hormones that put together you to combat, flee, or freeze. As these stress hormones flood your physique, they suppress the manufacturing of reproductive hormones like testosterone.15
This high-cortisol, low-testosterone phenomenon is a probable consequence of thousands and thousands of years of evolution.
Early people who have been extra desirous about mating than fleeing from sharp-clawed wild animals didn’t normally reside lengthy sufficient to go their genes to the following technology.
Nevertheless, not all short-term stressors dampen testosterone. Some can elevate it quickly, together with examination stress or train.16
So, purpose for the stress candy spot the place you’re feeling energized and engaged with life however not so busy and harried that you don’t have any time to calm down, sleep, or take pleasure in life.
(Be taught extra: Easy methods to inform the distinction between good stress and dangerous stress.)
Testosterone optimizer #7: Stop zinc deficiency.
As an authorized well being coach, it’s out of your scope of observe to advocate dietary supplements to deal with a situation like hypogonadism.
As well as, the enhance somebody would possibly get from a complement pales compared to the six items of recommendation above, or to testosterone remedy.
With that necessary caveat out of the best way…
There’s a correlation between low zinc consumption and low testosterone ranges.17 18
Nevertheless, to learn from supplementation, somebody should actually be poor within the mineral. Merely topping off somebody’s already sufficient zinc shops doubtless received’t result in a testosterone enhance, and should even trigger hurt.
Checking for and treating a mineral deficiency requires the experience of somebody skilled in medical vitamin remedy. In the event you lack this coaching, encourage shoppers with low testosterone to speak to their healthcare professionals about whether or not a zinc complement would possibly assist.
Use the Deep Well being lens
Let’s circle again to Dr. Berardi’s speculation, first talked about at first of this story:
Some evolutionary biologists have certainly theorized that males developed to have increased testosterone ranges after they’re youthful (to encourage mating) and decrease ranges after they’re older (to encourage parenting).19
Nevertheless, that is extra of a idea than a certainty.
What we are able to say with certainty is that this: There’s no one-size-fits-all protocol for wholesome testosterone ranges.
When testosterone drops after center age, some males really feel awful.
Even after they do all the pieces proper within the life-style division—exercising, consuming a nutritious diet, sleeping sufficient, and so forth—they’re unable to boost testosterone into the traditional vary. For these males, a healthcare skilled, thorough analysis, and, if warranted, testosterone remedy could be life-changing.
On the identical time, loads of different males proceed to thrive properly into (and previous!) center age.
Certain, they could be unable to pack on muscle like they used to. However, in the event that they’re paying consideration, suggests Dr. Berardi, they could discover different pluses. Possibly they’re extra affected person, nurturing, and empathetic, for instance.
“Don’t get me fallacious. I’d be very sad with an inappropriate or clinically important reducing of my hormone ranges,” says Dr. Berardi. “Nevertheless, if I can keep within the regular vary and symptom-free with good life-style practices, I don’t assume I’ve an excessive amount of to fret about.”
Dr. Berardi not too long ago turned 50.
“I’m at this stage the place I see an attention-grabbing fork within the highway,” he mentioned.
“Will I gracefully settle for getting old and see this as a brand new season—or will I combat towards it? I might shade my hair, do hair transplants, high up my T ranges, and get Botox injections. Or I might settle for that there will probably be some eventual decline and ask, ‘What am I getting in return?’”
