A couple of years again, PN co-founder John Berardi, PhD, posted a shirtless photograph 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 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 provided some thought-provoking concepts about testosterone and growing older.
Dr. Berardi’s take is the alternative of what you typically hear, particularly nowadays when…
- The mainstream opinion appears to be that declining testosterone is a harbinger of growing older, 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 retailers 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 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 liable for male sexual traits reminiscent of huge 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 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 instances lower than males.)
Probably due to its relationship with muscle progress and intercourse drive, lots of cisgender males consider testosterone in binary phrases, with decrease testosterone being unhealthy 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 professional, 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 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 will not be 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 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 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 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 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 power will now routinely blame their testosterone,” says Dr. Asafu-Adjei. “Their signs may 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 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 lots of nuances round hormone therapy,” says Dr. Asafu-Adjei.
“For instance, outdoors 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, 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 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 quite a bit on somebody’s persona, 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 affords 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 of the provide useful, they might 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 more likely 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 in addition generosity.
Some researchers seek advice from this phenomenon as “the male warrior speculation,” which holds that testosterone could operate to assist some males defend and cooperate with their “in group” (reminiscent of their household, associates, and coworkers) whereas concurrently punishing anybody seen as an outsider.6

So, once 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 unfavorable power steadiness.”
Dr. Berardi’s recommendation is usually not what males count on.
If their consuming and train routines recommend 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 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 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 section of speedy eye motion. This may occasionally 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 certainly one of these research, contributors 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 amount of sleep varies from one individual to a different. Nevertheless, should you routinely get fewer than seven hours and wake feeling exhausted, it’s an excellent guess you’re not getting sufficient.

Extra analysis is required to know whether or not these barely larger estrogen ranges are sufficient to contribute to hypogonadism.

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 per week.12)
Overtraining with out sufficient restoration can result in the alternative impact although, probably inflicting good points to plateau and suppressing testosterone.13

That’s essential for getting erections.
A research of 21,469 males discovered that those that consumed meals in line with the Mediterranean eating regimen had a decrease threat of growing erectile dysfunction over ten years in comparison with males who didn’t comply with the eating regimen.14
“Mediterranean diets are additionally recognized to advertise coronary heart well being,” says Dr. Asafu-Adjei.
The Mediterranean eating regimen emphasizes fruit, greens, entire grains, nuts and legumes, and wholesome fat from meals like olive oil, eggs, and fatty fish. It de-emphasizes crimson and processed meat, sugar-sweetened drinks, and sodium.
Nevertheless, consuming patterns that heart on minimally processed entire meals probably provide the identical advantages.

Testosterone optimizer #6: Keep away from power emotional stress.
Once you’re below stress, your physique produces cortisol and different hormones that put together you to battle, 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 hundreds of thousands of years of evolution.
Early people who had been extra occupied with mating than fleeing from sharp-clawed wild animals didn’t often stay lengthy sufficient to move their genes to the following era.
Nevertheless, not all short-term stressors dampen testosterone. Some can increase it briefly, together with examination stress or train.16
So, goal 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 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 apply 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 necessary caveat out of the way in which…
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 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 diet remedy. In case 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 in the beginning of this story:
Some evolutionary biologists have certainly theorized that males advanced to have larger 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 way of life 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 similar time, loads of different males proceed to thrive properly into (and previous!) center age.
Positive, they might 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. Perhaps they’re extra affected person, nurturing, and empathetic, for instance.
“Don’t get me flawed. I’d be very sad with an inappropriate or clinically vital 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 assume 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 highway,” he stated.
“Will I gracefully settle for growing older and see this as a brand new season—or will I battle 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 will likely be some eventual decline and ask, ‘What am I getting in return?’”
