Just a few 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 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 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 getting older.
Dr. Berardi’s take is the other of what you typically hear, particularly as of late when…
- The mainstream opinion appears to be that declining testosterone is a harbinger of getting older, frailty, and impotence—to not point out a menace 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 purchasers—or only a common dude hoping to age effectively—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 comparable to huge muscle mass, deep voices, and bushy 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 occasions lower than males.)
Probably due to its relationship with muscle development and intercourse drive, a variety of cisgender males consider testosterone in binary phrases, with decrease testosterone being unhealthy and better testosterone being good.
Nonetheless, 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 professional, and assistant professor of urology at Loyola College Chicago-Stritch Faculty of Medication.

Low testosterone vs. decrease testosterone
Testosterone ranges naturally ebb with age, with most males shedding 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 count on their testicles to shrink 15 %.3)
Nonetheless, age-related drops in testosterone aren’t 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 sort 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 are feeling fatigued and do a severe quantity in your intercourse drive, however it will probably 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 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 shopper 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 vitality will now routinely blame their testosterone,” says Dr. Asafu-Adjei. “Their signs may 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 you or your shopper 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 intensive workup is required.
“There are overlapping signs with low testosterone in addition to a variety of nuances round hormone remedy,” says Dr. Asafu-Adjei.
“For instance, exterior of your complete 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 foundation of the issue.”
So, if you happen to 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. Nonetheless, the affiliation between the hormone and conduct 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 lots 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 provides from a proposer. If somebody deemed the proposal too low, they might reject the provide and punish the individual for making such a substandard ask. Alternatively, in the event that they thought-about the provide useful, they might 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 had been extra prone to punish proposers, particularly in the event that they thought-about the provide unfair. Nonetheless, 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 confer with this phenomenon as “the male warrior speculation,” which holds that testosterone might perform to assist some males defend and cooperate with their “in group” (comparable to their household, buddies, and coworkers) whereas concurrently punishing anybody seen as an outsider.6

They work out lots and watch what they eat. In different phrases, they’re males experiencing mid- to long-term unfavourable vitality stability.”
Dr. Berardi’s recommendation is usually not what males count on.
If their consuming and train routines recommend they’re in a persistent unfavourable vitality 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 typically fixes all the pieces,” 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 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 fast 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 in all these research, contributors slept simply 5 hours an evening for eight days, leading to a ten to fifteen % drop in daytime testosterone ranges. 9

Overtraining with out sufficient restoration can result in the other impact although, probably inflicting positive factors to plateau and suppressing testosterone.13

That’s essential for getting erections.
A examine of 21,469 males discovered that those that consumed meals per the Mediterranean weight loss program had a decrease threat of growing erectile dysfunction over ten years in comparison with males who didn’t observe the weight loss program.14
“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 probably provide the identical advantages.

Testosterone optimizer #6: Keep away from persistent emotional stress.
Whenever you’re beneath 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 thousands and thousands of years of evolution.
Early people who had been extra considering mating than fleeing from sharp-clawed wild animals didn’t normally dwell lengthy sufficient to go their genes to the following era.
Nonetheless, not all short-term stressors dampen testosterone. Some can increase it briefly, together with examination stress or train.16
So, intention for the stress candy spot the place you are feeling energized and engaged with life however not so busy and harried that you don’t have any time to chill out, sleep, or get pleasure from life.
(Be taught extra: inform the distinction between good stress and unhealthy stress.)
Testosterone optimizer #7: Stop zinc deficiency.
As a licensed well being coach, it’s out of your scope of observe to suggest 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 vital caveat out of the way in which…
There’s a correlation between low zinc consumption and low testosterone ranges.17 18
Nonetheless, to profit 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 increase, and should even trigger hurt.
Checking for and treating a mineral deficiency requires the experience of somebody skilled in medical vitamin remedy. If you happen to lack this coaching, encourage purchasers 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 firstly 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 idea 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 pieces proper within the life-style 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 may be life-changing.
On the similar time, loads of different males proceed to thrive effectively 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 incorrect. I’d be very sad with an inappropriate or clinically important decreasing of my hormone ranges,” says Dr. Berardi. “Nonetheless, if I can keep within the regular vary and symptom-free with good life-style practices, I don’t suppose I’ve an excessive amount of to fret about.”
Dr. Berardi just 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 getting older and see this as a brand new season—or will I struggle towards it? I might colour 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?’”
