Just a few years again, PN co-founder John Berardi, PhD, posted a shirtless picture of himself on his forty seventh birthday.
He referred to 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 publish that whereas he wasn’t towards testosterone alternative remedy (TRT) for individuals who wanted it, he himself was not on this remedy, and his testosterone ranges had been boringly “regular.” He additionally supplied some thought-provoking concepts about testosterone and ageing.
Dr. Berardi’s take is the alternative of what you typically hear, particularly today when…
- The mainstream opinion appears to be that declining testosterone is a harbinger of ageing, frailty, and impotence—to not point out a menace to masculinity.
- Rising numbers of middle-aged males are ditching conventional medical checkups for males’s-focused telehealth clinics focusing on testosterone enhancement.1
- Reddit communities have popped up solely to obsess over neuroscientist Andrew Huberman’s complement suggestions for optimizing testosterone.
- Media shops pump out story after story about “testosterone boosting” meals to eat and “testosterone decreasing” meals to keep away from.
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 nicely—it’s simple to really feel overwhelmed and confused by the conflicting data.
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 liable for male sexual traits akin to large muscle groups, deep voices, and furry chests. It’s a chemical messenger that performs a key function in varied processes all through the physique, together with sperm manufacturing and bone density.
(In girls, who additionally want testosterone to maintain varied 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 occasions lower than males.)
Presumably due to its relationship with muscle development and intercourse drive, a number 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 skilled, and assistant professor of urology at Loyola College Chicago-Stritch Faculty of Medication.
Because the chart beneath reveals, the risks of extraordinarily low testosterone are just like the dangers of extraordinarily excessive quantities (usually solely achievable with the usage of anabolic steroids).

Low testosterone vs. decrease testosterone
Testosterone ranges naturally ebb with age, with most males shedding about 1 to 2 p.c yearly beginning round age 40. By age 75, most males have 30 p.c much less of the hormone than they did at age 25.2
(Enjoyable truth: Between ages 25 and 80, males can count on their testicles to shrink 15 p.c.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 p.c of males older than 45 and 30 to 50 p.c of males who’ve weight problems or kind 2 diabetes, in line with the Endocrine Society, one of many skilled public well being organizations that units hypogonadism remedy pointers.
Not solely can overly low testosterone make you’re feeling fatigued and do a severe quantity in your intercourse drive, however it might probably 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 become older, 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 should you or your consumer have a lot 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 robotically blame their testosterone,” says Dr. Asafu-Adjei. “Their signs is likely to be associated to testosterone, however in addition they may very well 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 vital.
Such a doctor can display screen you or your consumer for dozens of different issues (like stress and poor sleep) and circumstances (like diabetes, weight problems, or sleep apnea) that both mimic the signs of hypogonadism or intervene 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 number of nuances round hormone remedy,” says Dr. Asafu-Adjei.
“For instance, exterior of your whole testosterone, we additionally have a look at your testosterone-to-estrogen ratio and different associated hormones. That’s why it’s so vital 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, should you focus on 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 way 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 supply and punish the individual for making such a substandard ask. Alternatively, in the event that they thought of the supply useful, they may settle for it in addition to reward the individual.5
Researchers injected a few of the males with testosterone as they performed the sport.
As anticipated, gamers handled with the hormone had been extra prone to punish proposers, particularly in the event that they thought of the supply unfair. Nevertheless, in the event that they perceived the supply as honest, they rewarded the proposer extra generously.
The elevated testosterone amplified aggression, but in addition generosity.
Some researchers consult with this phenomenon as “the male warrior speculation,” which holds that testosterone might operate to assist some males defend and cooperate with their “in group” (akin to their household, buddies, and coworkers) whereas concurrently punishing anybody seen as an outsider.6

They work out quite a bit and watch what they eat. In different phrases, they’re males experiencing mid- to long-term unfavorable power stability.”
Dr. Berardi’s recommendation is usually not what males count on.
If their consuming and train routines counsel they’re in a power unfavorable power scenario, he merely recommends they eat an additional wholesome snack or two a day.
“In conditions like this, including a pair hundred additional energy of high-quality protein and carbohydrate usually fixes every little thing,” he says.
These added energy may come from a pair scoops of whey protein combined in milk with a nut butter and banana sandwich on the facet, 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.

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 phase of speedy eye motion. This will clarify why varied 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 in every of these research, individuals slept simply 5 hours an evening for eight days, leading to a ten to fifteen p.c drop in daytime testosterone ranges. 9
The correct quantity of sleep varies from one individual to a different. Nevertheless, should you routinely get fewer than seven hours and wake feeling exhausted, it’s wager you’re not getting sufficient. When you wake unrefreshed or battle to sleep soundly, our 14-day sleep plan may also help.

Extra analysis is required to know whether or not these barely increased estrogen ranges are sufficient to contribute to hypogonadism.
Within the meantime, nonetheless, a wholesome physique composition is significant for total good well being and might also assist to optimize testosterone.

Nevertheless, endurance train may also assist, offering you train on the proper depth, finds analysis. (That’s half-hour of rigorous exercise, 4 to 5 occasions per week.12)
Overtraining with out sufficient restoration can result in the alternative impact although, probably inflicting beneficial properties to plateau and suppressing testosterone.13

That’s essential for getting erections.
A examine of 21,469 males discovered that those that consumed meals according to the Mediterranean food regimen had a decrease danger of growing erectile dysfunction over ten years in comparison with males who didn’t observe the food regimen.14
“Mediterranean diets are additionally identified to advertise coronary heart well being,” says Dr. Asafu-Adjei.
The Mediterranean food regimen emphasizes fruit, greens, complete 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 complete meals probably supply the identical advantages.

Testosterone optimizer #6: Keep away from power emotional stress.
If 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 hundreds of thousands of years of evolution.
Early people who had been extra interested by mating than fleeing from sharp-clawed wild animals didn’t normally stay lengthy sufficient to go their genes to the subsequent technology.
Nevertheless, not all short-term stressors dampen testosterone. Some can elevate it briefly, 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 chill out, sleep, or take pleasure in life.

Testosterone optimizer #7: Forestall zinc deficiency.
As a licensed 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 may get from a complement pales compared to the six items of recommendation above, or to testosterone remedy.
With that vital 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 really be poor within the mineral. Merely topping off somebody’s already ample zinc shops probably gained’t result in a testosterone enhance, and will even trigger hurt.
Checking for and treating a mineral deficiency requires the experience of somebody educated in medical vitamin remedy. When you lack this coaching, encourage shoppers with low testosterone to speak to their healthcare professionals about whether or not a zinc complement may assist.
Use the Deep Well being lens
Let’s circle again to Dr. Berardi’s speculation, first talked about at the start of this story:
Some evolutionary biologists have certainly theorized that males advanced 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 every little thing proper within the way of life division—exercising, consuming a nutritious diet, sleeping sufficient, and so forth—they’re unable to boost testosterone into the conventional 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 nicely 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 unsuitable. I’d be very sad with an inappropriate or clinically important decreasing of my hormone ranges,” says Dr. Berardi. “Nevertheless, if I can keep within the regular vary and symptom-free with good way of life practices, I don’t suppose 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 fascinating fork within the highway,” he mentioned.
“Will I gracefully settle for ageing and see this as a brand new season—or will I combat towards it? I may colour my hair, do hair transplants, prime up my T ranges, and get Botox injections. Or I may settle for that there shall be some eventual decline and ask, ‘What am I getting in return?’”
