Testoboosters

Testosterone boosters – compared by evidence, not just sold

We stock Tongkat Ali (in more strengths and colors than any other Swedish retailer), Fadogia Agrestis, Turkesterone, Ecdysterone, Shilajit, Boron, Zinc, Magnesium, Vitamin D3, Maca – and more in combination products. See how they rank against each other by clinical evidence in our comparison guide to the best testosterone boosters 2026.

What do we sell in this category?

Tongkat Ali — the flagship

Our best-selling and most documented option. Available in several extract strengths (up to 200:1, 4% eurycomanone) and color variants (yellow, red, black). See the complete guide to Tongkat Ali for dosage and how to interpret extract strength.

Boron and Zinc — minerals with a documented link to testosterone

Boron can lower SHBG and increase free testosterone. Zinc is a well-known nutrient — zinc deficiency is linked to low testosterone, so supplementation is most relevant if your diet is actually deficient.

Magnesium and Vitamin D3 — basic nutritional support

Both are linked to normal hormone function, especially in case of deficiency. Common complements to a testosterone booster stack rather than a first choice on their own.

Fadogia Agrestis

Popular in training circles, but human data is still limited — mostly animal studies. We sell it because there is demand, but the evidence is weaker than for Tongkat Ali and Boron.

Turkesterone & Ecdysterone

Plant sterols that work via a different mechanism (protein synthesis/anabolic signaling) than classic testosterone boosters — they do not raise testosterone directly. Good for a muscle focus, but don't compare them directly with Tongkat Ali or Fadogia.

Maca and Shilajit

A tradition for energy and vitality, but limited human evidence specifically on testosterone. Choose these if you want to try a more traditional ingredient.

Combination products

King Test, Tongkat Trio and Androgenic Testo Growth combine several of the above in one product — good if you want to try a broader stack without buying each ingredient separately.

Which one suits you?

• Most documented single effect: Tongkat Ali.
• Suspect high SHBG: Boron.
• Poor diet: Zinc, Magnesium, Vitamin D3.
• Muscle focus rather than hormonal increase: Turkesterone/Ecdysterone.
• Want to try a niche ingredient: Fadogia Agrestis, Maca or Shilajit.
• Want a ready-made stack: one of the combination products.

Dosage and safety

• Always follow the product label — strength varies between manufacturers and extract ratios.
• Expect at least 4–6 weeks of continuous use before evaluating.
• Avoid if pregnant, breastfeeding or under 18.
• Consult a doctor if you have hormone-sensitive conditions or are on ongoing medication.
• Competitive athletes: check the current prohibited list — Turkesterone has historically been discussed in anti-doping contexts.

Frequently asked questions

Which testosterone booster is best in 2026?

Based on the overall clinical evidence, Tongkat Ali is most strongly documented for actual testosterone increase at borderline-low levels. See the full comparison.

Is Turkesterone a testosterone booster?

Not in the classic sense — it does not raise testosterone, but works via a different, muscle-focused mechanism.

How quickly will I notice an effect?

Expect at least 4–6 weeks of continuous use for most of these.

Are testosterone boosters safe?

At studied doses yes, for healthy adults. Consult a doctor if you have hormone-sensitive conditions or are on medication.
