Our formulation lead. HARDER took six months of development with practising doctors and men who perform for a living, led by founder Jason Moody. Every dose in the panel below was argued over, tested and set on purpose. Nothing in this formula is there to pad a label.

The evidence
What the published research says.
These are human trials on the individual ingredients, not on HARDER as a finished product. Read the limits section below before drawing conclusions.
1,250 mg
Tongkat Ali
A 2022 systematic review and meta-analysis pooled nine studies, five of them randomised controlled trials, and found a significant improvement in total testosterone in men taking Eurycoma longifolia, in both healthy volunteers and men with low testosterone. The authors describe it as a promising option while noting more research is needed before clinical use.

12.5 mg
Ashwagandha
In a 16 week randomised, double-blind, placebo-controlled crossover trial in overweight men aged 40 to 70, ashwagandha extract was associated with a 14.7% greater increase in testosterone and an 18% greater increase in DHEA-S compared with placebo. A separate randomised trial reported improvements in well-being and sexual performance in adult men.
The trial used 300 mg a day of a root extract standardised to 5% withanolides. HARDER uses 12.5 mg standardised to 2.5%. That is a much smaller amount, so the trial result does not transfer to our dose.

The rest of the formula
Maca, Fenugreek, Shilajit, Horny Goat Weed, Tribulus, Panax Ginseng, Rhodiola, Ginkgo, Beet Root, Zinc, Boron and B vitamins each have their own body of research, at varying levels of quality and at doses that differ between studies. Every amount we use is printed on the supplement facts panel below so you can check it yourself.
The mechanism
Why a daily cycle, and not a one-off.
Testosterone is not produced on demand. It follows a daily rhythm, peaks in the morning, and does most of its rebuilding while you sleep. A product that only shows up once in a while is working against that.
Morning
Day+ supports the active window
Tongkat Ali, Maca, Panax Ginseng and Beet Root are taken when your natural testosterone is highest, alongside B vitamins for energy metabolism.
Overnight
Night+ supports recovery
Your body does most of its hormonal repair during sleep. Zinc, Boron, Shilajit and adaptogens are timed for that window rather than the middle of the day.
Cumulative
Weeks, not hours
Botanical and mineral effects build with consistent intake. This is why the research below runs over 8 to 24 weeks, and why we ask for 14 days before you judge it.
Being straight with you
What we do not claim.
- HARDER has not been through a clinical trial as a finished product. The research above is on individual ingredients, run by other people, and published independently of us.
- Studies use their own doses and extract ratios. Ours are printed below. Where they differ, the study result does not automatically transfer.
- HARDER is a dietary supplement. It is not a treatment for erectile dysfunction, hypogonadism or any other medical condition, and it is not a substitute for seeing a doctor.
- Results vary between men, and depend on where you are starting from, your sleep, your training and whether you actually take it daily.
- If you take prescription medication or have a medical condition, speak to your doctor before starting.
