What are peptides and why is everyone taking them?
Peptides are everywhere in wellness — from GLP-1s to BPC-157. Here’s what they are, why they’re trending, and what the clinical evidence shows.
Women have more testosterone than estrogen, but testosterone for women is barely tested or treated. Here’s why that’s about to change.

For decades, testosterone has been framed as the “male hormone.” But that framing leaves out a big part of the story: testosterone in women’s health.
Testosterone is actually the most abundant biologically active sex hormone in a woman’s body. Yes — more than estrogen. More than progesterone. And unlike those hormones, testosterone tends to decline without much clinical attention.
By your 40s, levels have dropped to nearly half compared to your mid-20s. By menopause, the drop is even steeper.
So why aren’t we talking about it more?
That’s starting to change. New research, updated clinical guidelines, and a growing wave of patient advocacy are bringing testosterone for women into the mainstream conversation (where it should have been all along.)
Let’s dig in to learn more.
Testosterone gets produced in two places in the female body: the ovaries and the adrenal glands. And it does a lot more than affect libido.
Receptors for testosterone exist throughout the body — the brain, muscles, skin, bones, cardiovascular system, and even the urogenital tract. Which means when levels drop, the effects show up in places most people wouldn’t think to look.
Here’s what testosterone supports in women:
It’s a hormone that plays a major role in how you feel in your body physically, mentally, and emotionally.
Testosterone peaks in your mid-20s then gradually tapers off.
There’s no dramatic hormonal “event” like menopause to mark the shift. Instead, it’s subtle. And that’s part of the issue. Symptoms like low energy, reduced motivation, changes in body composition, or a fading libido often get written off as stress, aging, or burnout. Sometimes they are. But sometimes there’s a hormonal layer that just hasn’t been explored.
Here are some signs your testosterone might be low:
Many of these overlap with perimenopause, menopause, depression, burnout, or just life. Which is why testosterone often goes untested.
So how do you know if testosterone is the issue?
Blood testing. Specifically, total and free testosterone — ideally drawn in the morning when levels are the highest. Most premenopausal women fall in the range of 15 to 70 ng/dL total testosterone. When those symptoms line up with low free testosterone on blood testing, that can point to deficiency.
There is strong clinical evidence supporting testosterone therapy for women, especially for one specific use: persistent, distressing low libido (also called hypoactive sexual desire disorder, or HSDD) in postmenopausal women. Many randomized controlled trials support this.
The trials consistently show:
But in the U.S., there’s still no FDA-approved testosterone product specifically for women. Every prescription is off-label.
Which means, most testosterone therapy for women involves either:
or
Other countries, like Australia, have already approved women-specific formulations. In the U.S., those options are still in development.
A transdermal testosterone patch designed specifically for women is now in clinical trials. If successful, it could become the first FDA-approved testosterone therapy for women. But, a finalized approval is likely years away.
For now, treatment exists, but it requires a provider who will prescribe it off-label and properly monitor it.
If you work with women over 35 you’ve likely seen the pattern: women doing everything “right.” Dialing in nutrition. Supporting their nervous system. Investing in movement, sleep, and supplementation. And still not feeling like themselves.
In some cases, testosterone is the missing piece. Not always, but often enough that it deserves a place in the conversation. Because when a hormone that influences energy, strength, mood, and libido is overlooked? The ripple effects are significant.
This is your opportunity to be the wellness business that catches what standard care misses — to be the practice your clients tell your friends about. And the one that finally connects the dots for women who’ve been struggling for years.
That looks like:
Is testosterone therapy safe for women?
When dosed properly (meaning levels that bring a woman back into normal female range), the major reviews and guidelines points to a strong safety profile. The side effects people worry about (acne, unwanted hair growth) only really show up at doses well above what’s normal for women. A blood draw every three to six months helps keep everything in range. Emerging research suggests testosterone might have a protective effect in breast tissue in some populations including postmenopausal women and transmasculine patients, but the evidence is still evolving.
Will testosterone make me bulk up or grow facial hair?
Not at the doses prescribed for women, when dosed correctly. Women’s testosterone doses are 10 to 20 times lower than male doses. Bulking and unwanted hair growth happen at doses far higher than what’s prescribed for women.
Who should consider getting tested?
Women experiencing the following symptoms, especially women in perimenopause or postmenopause:
Younger women with similar symptoms after losing ovarian function (from surgery, certain treatments, or other causes) should also be tested.
How quickly will I notice a change?
Most women notice improvements in energy, mental clarity, and mood within four to eight weeks. Libido improvements typically take eight to twelve weeks. Muscle and strength gains require both adequate testosterone and consistent training, which typically takes about 12 to 16 weeks for measurable change.
Testosterone is still underrecognized in women’s health, but thankfully it’s no longer invisible. Between growing research, shifting clinical perspectives, and women advocating for deeper answers, the conversation is expanding.
And that’s a good thing.
Because the more complete the hormonal picture becomes, the more precise and effective care can be.
So take this seriously now, and you become part of the next wave of women’s care.
That’s the wave Altro Health is built to power.
