He known as it his “anti-regress pic” and thanked 30 years of squats, deadlifts, presses, and chin-ups—amongst different workout routines—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 in opposition to 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 provided some thought-provoking ideas about testosterone and aging.
Dr. Berardi’s take is the other 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 risk to masculinity.
- Rising numbers of middle-aged males are ditching conventional medical checkups for males’s-focused telehealth clinics focusing on testosterone enhancement.1

- Media retailers pump out story after story about “testosterone boosting” meals to eat and “testosterone reducing” 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 properly—it’s simple to really feel overwhelmed and confused by the conflicting info.
Are declining testosterone ranges regular?
Do testosterone-boosting complement regimens really 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 chargeable for male sexual traits equivalent to massive muscle groups, 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.)
Probably due to its relationship with muscle progress and intercourse drive, a whole lot of cisgender males consider testosterone in binary phrases, with decrease testosterone being dangerous and better testosterone being good.
Nevertheless, it’s extra correct to consider 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 exhibits, the risks of extraordinarily low testosterone are much 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 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 truth: Between ages 25 and 80, males can count on 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 keeping 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 are feeling fatigued and do a critical quantity in your intercourse drive, however it may well 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 shopper 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 vitality will now robotically blame their testosterone,” says Dr. Asafu-Adjei. “Their signs is likely to 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 essential.
Such a doctor can display screen you or your shopper 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 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 intensive workup is required.
“There are overlapping signs with low testosterone in addition to a whole lot of nuances round hormone therapy,” says Dr. Asafu-Adjei.
“For instance, outdoors 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 essential to go to somebody who is aware of what they’re doing. They’ll take a deeper dive to determine the foundation of the issue.”
So, should you concentrate 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 conduct 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 rather a lot on somebody’s character, upbringing, context, social norms, and extra.
For instance, in one experiment, researchers requested forty younger males to play a online game that concerned accepting and rejecting provides 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 of the provide useful, they may settle for it in addition to reward the individual.5
Researchers injected among 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 of the provide unfair. Nevertheless, in the event that they perceived the provide as honest, they rewarded the proposer extra generously.
The elevated testosterone amplified aggression, but additionally generosity.
Some researchers seek advice from this phenomenon as “the male warrior speculation,” which holds that testosterone might operate to assist some males defend and cooperate with their “in group” (equivalent to their household, buddies, and coworkers) whereas concurrently punishing anybody seen as an outsider.6

They work out rather a lot and watch what they eat. In different phrases, they’re males experiencing mid- to long-term adverse vitality stability.”
Dr. Berardi’s recommendation is usually not what males count on.
If their consuming and train routines counsel they’re in a continual adverse vitality 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 typically fixes every little thing,” 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.

As you sleep, ranges rise once more, peaking throughout your first phase of speedy eye motion. This will likely 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

Nevertheless, endurance train can even assist, offering you train on the proper depth, finds analysis. (That’s half-hour of rigorous exercise, 4 to 5 instances per week.12)

“Mediterranean diets are additionally recognized to advertise coronary heart well being,” says Dr. Asafu-Adjei.
The Mediterranean diet emphasizes fruit, greens, entire grains, nuts and legumes, and wholesome fat from meals like olive oil, eggs, and fatty fish. It de-emphasizes pink and processed meat, sugar-sweetened drinks, and sodium.
Nevertheless, consuming patterns that heart on minimally processed entire meals doubtless provide the identical advantages.

Testosterone optimizer #6: Keep away from continual emotional stress.
While you’re underneath stress, your physique produces cortisol and different hormones that put together you to struggle, 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 possible consequence of tens of millions of years of evolution.
Early people who have been extra serious about mating than fleeing from sharp-clawed wild animals didn’t normally reside lengthy sufficient to go their genes to the subsequent 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 are feeling energized and engaged with life however not so busy and harried that you haven’t any time to loosen up, sleep, or get pleasure from 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 increase somebody may get from a complement pales compared to the six items of recommendation above, or to testosterone remedy.
With that essential caveat out of the way in which…
There’s a correlation between low zinc consumption and low testosterone ranges.17 18
Nevertheless, to profit from supplementation, somebody should actually be poor within the mineral. Merely topping off somebody’s already enough zinc shops doubtless gained’t result in a testosterone increase, and should even trigger hurt.
Checking for and treating a mineral deficiency requires the experience of somebody educated in medical diet 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 developed to have greater testosterone ranges once they’re youthful (to encourage mating) and decrease ranges once 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 once they do every little thing proper within the life-style division—exercising, consuming a nutritious diet, sleeping sufficient, and so forth—they’re unable to lift testosterone into the traditional vary. For these males, a healthcare skilled, thorough analysis, and, if warranted, testosterone remedy will be life-changing.
On the identical time, loads of different males proceed to thrive properly into (and previous!) center age.
Positive, 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 may 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 street,” he stated.
“Will I gracefully settle for ageing and see this as a brand new season—or will I struggle in opposition to it? I might colour 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?’”
