A generation of men running on empty

Research shows average testosterone in American men has fallen across generations, beyond normal age-related decline (Travison et al., 2007). Levels also drop as men age.

Bad sleep. Stress. Processed food. Most men feel flatter, softer and foggier, and just write it off as 'getting older'. Then the doctor says 'normal range'.

It doesn't have to stop there. HisLabs is one natural ingredient, taken as a short course, so you can check what it does on your own bloodwork.*

Built for the man stuck in the middle

“If you're an athlete and always training hard from teens to 40 there's a peak and then a plateau which starts to gradually decline.”

Still lifting at 40

Natural · trains hard · no TRT

You've trained for years and you're not touching TRT. You want to back your own production, not replace it.

“Doctor said this was alright but I felt like this was way lower than I wanted to be.”

"Normal range"

Bloods fine · feels flat

Your doctor says you're in range. You don't feel it. You want to see what moves your own numbers.

Tongkat · ashwa · fadogia · turk

You've bought the lot and felt nothing. You want one thing, fully dosed, with a reason behind it.

The plateau

Training dialled · bar stuck

Program's right, diet's right, the numbers haven't moved in months. Another scoop of creatine isn't it.

“I just want to encourage people to really try before resorting to TRT.”

Not ready for TRT

No needles · no script

TRT is a big, often long-term call. You want to try something measured first.

“If you are curious about the data go to your doc and get bloodwork done.”

Frequently asked questions

What is HisLabs Ferula?

A single-ingredient men's supplement: 500 mg Ferula hermonis root extract per capsule, with 5 mg black pepper extract for absorption. No proprietary blends.

Who is it for?

Men 18+ who feel flat, tired or not like themselves, who've tried the usual boosters and aren't ready for TRT. On medication, being treated for low T or trying for a baby? Speak to your doctor first.

How do I take it?

Daily for the first 7 days, then three times a week for weeks 2–4, at least 48 hours apart. Then rest 30 days. Do not exceed the course.

Do I need to cycle it?

Yes. In animal research single doses raised testosterone but daily dosing for 10+ days lowered it. HisLabs is built as a pulsed course with a rest, not a daily pill for life.

Is Ferula a hormone?

No. It's a plant root extract with no testosterone or other hormones in it. It is hormonally active, which is why it's for men only and sold as a measured course.
