How Much Shilajit Per Day for Testosterone? Dosage Guide
By TRT NYC Editorial Team
TL;DR — Key Takeaways
- The evidence-based dose is 250 mg of purified shilajit twice a day (500 mg/day).
- A 2015 clinical trial found this raised total testosterone ~20% over 90 days in men aged 45–55.
- Clinical studies used 200–500 mg/day of purified shilajit.
- Only use purified, third-party-tested shilajit, raw shilajit can contain heavy metals.
- It may modestly help but it won’t replace TRT if you’re genuinely low.
Research used 250 mg of purified shilajit twice daily (500 mg/day) for 90 days, a 2015 trial found ~20% higher total testosterone in men aged 45–55. So 250–500 mg/day purified is the evidence-based range. Only use purified, third-party-tested shilajit (raw can contain heavy metals); it won’t replace TRT if you’re truly low.
Shilajit is one of the few “natural testosterone” supplements with actual human evidence behind it. Here’s exactly how much to take and the safety catch most people miss. (For the bigger picture, see our complete TRT guide.)
How Much Shilajit Per Day for Testosterone?
The dose used in research, and the one most worth following, is 250 mg of purified shilajit, twice a day (500 mg total per day). Clinical studies have used 200–500 mg/day of purified shilajit for up to 90 days, and 500 mg/day split into two 250 mg doses is the most-validated “sweet spot” for testosterone support.
Key fact: In a 2015 clinical trial, 250 mg of purified shilajit twice daily for 90 days raised total testosterone by about 20% in men aged 45–55.
Start at the lower end if you’re new to it, and don’t assume “more is better”, the research didn’t test megadoses.
Does Shilajit Actually Increase Testosterone?
Unusually for a “natural booster,” yes, there’s real (if limited) human evidence. The key study is a double-blind, placebo-controlled trial (Pandit et al., Andrologia, 2016) in healthy men aged 45–55:
- +20.5% total testosterone and +19.1% free testosterone vs placebo over 90 days
- DHEAS also increased
- LH and FSH stayed balanced (a good sign)
That’s far stronger than the evidence behind most supplements, unlike, say, celery. Still, it’s one main trial, the effect is modest, and it’s best seen as a support alongside the proven basics in best supplements to take while on TRT.
How to Take Shilajit (Timing & Form)
- Dose: 250 mg purified shilajit, twice daily (morning and evening) = 500 mg/day.
- Form: Resin or capsule is fine, what matters is purity (see safety below).
- With or without food: Generally well tolerated either way; with food can ease any stomach upset.
- Consistency: The study ran 90 days, give it weeks to months, not days.
- Track it: Check your testosterone before and after with the right test rather than guessing.
The Safety Catch: Purity and Heavy Metals
This is the most important part, and where cheap shilajit is dangerous:
Raw, unpurified shilajit can be contaminated with heavy metals, fungi, and other contaminants.
So purity matters more here than with almost any other supplement. Rules:
- Only buy purified, third-party-tested shilajit from reputable brands.
- Avoid raw/unprocessed shilajit of unknown origin.
- At research doses (250–500 mg/day) of purified shilajit, studies reported no significant adverse effects but that depends entirely on the product being clean.
If you have any medical condition or take medications, clear it with your doctor first.
Can Shilajit Replace TRT?
No. Shilajit may give a modest testosterone bump in some men, but it’s not a substitute for TRT if you have genuinely low testosterone. If you have real low testosterone symptoms and confirmed low levels (vs normal ranges), the reliable fix is medical, see whether TRT is right for you. Think of shilajit as a possible add-on for borderline/healthy men, not a treatment for true deficiency.
The Bottom Line
How much shilajit per day for testosterone? The evidence-based dose is 250 mg of purified shilajit twice daily (500 mg/day), the regimen a 2015 trial showed raised total testosterone ~20% over 90 days. Stay in the 200–500 mg/day range, use only purified, third-party-tested product (raw shilajit can carry heavy metals), and give it weeks to months. It may modestly help, but it won’t replace TRT for genuinely low testosterone.
👉 See if it’s actually working: check your testosterone before and after a few months with an at-home test kit, and talk to a licensed provider if your levels are low.
Frequently Asked Questions
How much shilajit should you take per day for testosterone?
The evidence-based dose is 250 mg of purified shilajit twice daily, totaling 500 mg per day, as used in clinical research. Studies have used 200–500 mg/day of purified shilajit for up to 90 days. Start at the lower end and use only purified, tested product.
Does shilajit actually increase testosterone?
Yes, with real but limited evidence. A 2015 double-blind trial found purified shilajit (250 mg twice daily for 90 days) raised total testosterone about 20% and free testosterone about 19% versus placebo in men aged 45–55. The effect is modest but better-supported than most natural boosters.
When should you take shilajit?
Most regimens split the dose into morning and evening (250 mg each). It’s generally well tolerated with or without food, though taking it with food can reduce any stomach upset. Consistency over weeks to months matters more than exact timing.
How long does shilajit take to work for testosterone?
The key study measured results over 90 days, so give it weeks to months rather than expecting quick changes. Track your testosterone before and after a few months of consistent use to see whether it’s actually helping you.
Is shilajit safe?
Purified, third-party-tested shilajit at 250–500 mg/day showed no significant adverse effects in studies. The real danger is raw or unpurified shilajit, which can contain heavy metals, fungi, or other contaminants. Only use purified products from reputable brands, and consult your doctor if you take medications.
Can shilajit replace TRT?
No. Shilajit may modestly support testosterone in some men, but it’s not a substitute for TRT if you have genuinely low testosterone. For confirmed low levels and symptoms, medical treatment is the reliable option; shilajit is better viewed as a possible add-on, not a cure.
