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 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 put up 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 have been boringly “regular.” He additionally supplied some thought-provoking concepts about testosterone and growing old.
Dr. Berardi’s take is the other of what you typically hear, particularly nowadays when…
- The mainstream opinion appears to be that declining testosterone is a harbinger of growing old, 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 specializing in testosterone enhancement.1
- Reddit communities have popped up solely to obsess over neuroscientist Andrew Huberman’s complement suggestions for optimizing testosterone.
- 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 straightforward 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 accountable for male sexual traits akin to large muscular tissues, deep voices, and bushy chests. It’s a chemical messenger that performs a key position in varied processes all through the physique, together with sperm manufacturing and bone density.
(In ladies, 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 unhealthy and better testosterone being good.
Nonetheless, 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 reveals, the hazards of extraordinarily low testosterone are just like the dangers of extraordinarily excessive quantities (sometimes solely achievable with using 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 reality: Between ages 25 and 80, males can anticipate their testicles to shrink 15 p.c.3)
Nonetheless, 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 response to the Endocrine Society, one of many skilled public well being organizations that units hypogonadism remedy tips.
Not solely can overly low testosterone make you are feeling fatigued and do a severe 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 power,” 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 massive 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 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 routinely blame their testosterone,” says Dr. Asafu-Adjei. “Their signs is perhaps associated to testosterone, however additionally 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 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 take 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, 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. Nonetheless, the affiliation between the hormone and habits is way more complicated.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 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 of the provide helpful, 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 have been extra more likely to punish proposers, particularly in the event that they thought of the provide unfair. Nonetheless, in the event that they perceived the provide as truthful, they rewarded the proposer extra generously.
The elevated testosterone amplified aggression, but additionally generosity.

They work out rather a lot and watch what they eat. In different phrases, they’re males experiencing mid- to long-term unfavorable vitality stability.”
Dr. Berardi’s recommendation is usually not what males anticipate.
If their consuming and train routines recommend they’re in a power unfavorable 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 usually fixes all the things,” he says.
These added energy might come from a pair scoops of whey protein blended 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.

As you sleep, ranges rise once more, peaking throughout your first phase of fast eye motion. This may increasingly clarify why varied sleep problems—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 all 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

“Mediterranean diets are additionally identified to advertise coronary heart well being,” says Dr. Asafu-Adjei.
The Mediterranean weight loss program 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.
Nonetheless, consuming patterns that middle on minimally processed entire meals seemingly provide the identical advantages.

Testosterone optimizer #7: Forestall zinc deficiency.
As an authorized well being coach, it’s out of your scope of follow 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
Nonetheless, to learn from supplementation, somebody should actually be poor within the mineral. Merely topping off somebody’s already sufficient zinc shops seemingly received’t result in a testosterone increase, and will even trigger hurt.
Checking for and treating a mineral deficiency requires the experience of somebody educated in medical diet 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 may 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 larger testosterone ranges once they’re youthful (to encourage mating) and decrease ranges once they’re older (to encourage parenting).19
Nonetheless, that is extra of a principle than a certainty.
What we will 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 all the things proper within the way of life division—exercising, consuming a nutritious diet, sleeping sufficient, and so forth—they’re unable to lift testosterone into the conventional vary. For these males, a healthcare skilled, thorough analysis, and, if warranted, testosterone remedy might 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 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 vital reducing of my hormone ranges,” says Dr. Berardi. “Nonetheless, 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 lately turned 50.
“I’m at this stage the place I see an fascinating fork within the street,” he mentioned.
“Will I gracefully settle for growing old and see this as a brand new season—or will I struggle towards it? I might coloration my hair, do hair transplants, prime up my T ranges, and get Botox injections. Or I might settle for that there shall be some eventual decline and ask, ‘What am I getting in return?’”
