Pros & Cons
Pros
- Full label with doses published
Cons
- No creatine or protein, the best-evidenced muscle supplements
- 'SARM' claim based on a mouse study
Who Is This For?
Recommended For:
We would not recommend it for building muscle. Trained adults should look first at protein intake and creatine monohydrate.
Not Recommended For:
Men taking sedative, hypnotic or anti-epileptic drugs (NuviaLab's own warning), men on prostate or blood-sugar medication without checking with their doctor (saw palmetto, bitter melon), anyone prone to acne (high-dose B12 and B6), and under-18s.
Summary
What is in it: bitter melon 600 mg, nettle, maca, beetroot and alfalfa at 200 mg each, shilajit 150 mg, Siberian ginseng 100 mg, saw palmetto 100 mg, pumpkin seed 75 mg, vitamins B6 and B12, zinc and selenium.
What is not in it: creatine or protein, two of the supplements the International Society of Sports Nutrition rates as having strong evidence for building muscle.
The claims: the page calls bitter melon compounds "SARMs"; the study behind that idea was in castrated mice. Maca did not change testosterone in its human trial, and the beetroot provides about 4 mg of nitrate, around 1% of the dose studied.
Returns are limited to 10 days from purchase, for unopened goods.
Ingredient Breakdown
The label, and the best evidence for each main ingredient.
- Bitter melon (Momordicin), 600 mg. The "SARM" claim appears to rest on a study in castrated mice fed bitter gourd powder for 23 weeks. There is no human muscle trial.
- Shilajit, 150 mg. A 90-day trial in men aged 45 to 55 found higher testosterone with 500 mg a day of purified shilajit. Muscle was not measured.
- Maca, 200 mg. A 12-week trial at 1,500 or 3,000 mg a day improved sexual desire but found no change in testosterone.
- Beetroot (2% nitrate), 200 mg, about 4 mg nitrate. The ISSN puts nitrate in the "limited or mixed evidence" group, at 300 to 600 mg a day.
- Nettle, alfalfa, Siberian ginseng, saw palmetto 100 mg, pumpkin seed 75 mg. No muscle trials found; saw palmetto and pumpkin seed are prostate herbs.
- Vitamin B12 1,000 mcg (40,000% of the reference intake), B6 6 mg, zinc 15 mg, selenium 55 mcg. Zinc and selenium are nutrient top-ups. High-dose B6 and B12 supplements have been linked to acne-like breakouts.
The missing basics: the ISSN review of sports supplements lists creatine monohydrate, protein, essential amino acids and HMB as having strong evidence for muscle, and calls creatine monohydrate the most effective supplement for muscle mass during training. Bulk Extreme contains none of them. See our page on creatine monohydrate.
What Bulk Extreme actually contains
| Ingredient | On the label | In the trials |
|---|---|---|
| Maca | 200 mg | 1500 mg13% |
| Beta-sitosterol | 15 mg | 60 mg25% |
| Saw palmetto | 100 mg | 320 mg31% |
| Selenium | 55 µg | 55 µg100% |
| Zinc | 15 mg | 8 mg188% |
Amounts are taken from the manufacturer’s own supplement facts panel. Where a label states a standardisation, the active fraction is what we compare, because the active is what the trials measured.
Dosage Analysis
Our Dose Check compares the label with the best human evidence.
- Creatine: 0 g, against about 3 g a day or more recommended for training.
- Nitrate (beetroot): about 4 mg vs 300 to 600 mg. About 1% of the lowest effective dose.
- Shilajit: 150 mg vs 500 mg a day. 30%.
- Maca: 200 mg vs 1,500 to 3,000 mg a day, 7% to 13%, and testosterone did not change even at those doses.
- Bitter melon: 600 mg; mouse data only.
The directions are three capsules a day during a meal with 300 ml of water. A bottle of 90 lasts a month.
Quality & Testing
Our Transparency Score checks five things a buyer can verify. Bulk Extreme scores 2 out of 5.
- Label with doses: yes. Every ingredient is dosed.
- Identifiable company: no. The Swiss and German sites name Key Player Limited, Dubai Airport Freezone; the US site names only "BulkExtreme.com" in Hong Kong. The label says Bulk Extreme is a registered trademark of NuviaLab Limited. No manufacturer.
- Refund terms in writing: yes. 10 calendar days from purchase, unused goods only.
- Independent testing shown: no.
- Study on the finished product: no.
The page promises "up to 95%" more muscle and says Bulk Extreme "eliminates the effects of testosterone deficiency", with no human study behind either claim. NuviaLab's FAQ warns against use with sedative, hypnotic or anti-epileptic drugs; the sales page does not.
Correction. An earlier version of this review showed a "Lab Tested" badge and said the product was third-party tested; no such testing is claimed anywhere. It also compared the formula with creatine, beta-alanine and whey, none of which is in it. We have corrected this.
Value for Money
Prices when we checked in September 2026:
- Swiss site (where our link leads): CHF 49.99 for 1 bottle, CHF 99.98 for 3, CHF 149.97 for 6.
- German site: €49.99, €99.98, €149.97.
- US site: $59.99, $119.98, $179.97. UK: £41.99.
Creatine monohydrate, the best-evidenced muscle supplement, costs far less on its own.
The return rule. The terms allow withdrawal "within 10 calendar days from the date of purchase", in writing, for goods with no signs of use, and state that EU law does not apply.
Side Effects & Safety
- Acne: supplements with high-dose B6 and B12 have been linked to acne-like breakouts, which usually clear after stopping.
- Medicine interactions: NuviaLab warns against combining it with sedative, hypnotic or anti-epileptic drugs.
The sales page says it should not cause any side effects. There is no clinical study on Bulk Extreme itself.
Final Verdict
Our Verdict
Bulk Extreme is a herbal testosterone-style blend sold as a muscle builder, without the two ingredients with the strongest evidence for muscle. Its headline claims rest on a mouse study and figures with no source, most doses are far below what was studied, and returns are limited to 10 days for unopened bottles. We do not recommend it. Train progressively, eat enough protein, and consider plain creatine monohydrate.
