Eron Plus Review 2026An Honest Look at the Label

What is in it:

• Eron Plus (2 capsules a day): L-arginine HCl 750 mg, plus 50 mg each of maca, tribulus, Korean ginseng and fenugreek, with vitamin E, B6 and zinc.
• Eron Plus Before (6 capsules): L-arginine HCl 3,000 mg, and nothing else.

What the evidence says:

• Arginine helped mild to moderate erectile dysfunction at 1,500 to 5,000 mg a day, taken daily, in 10 trials. The "Before" dose is in that range, but the trials did not use it on demand.
• The four herbs are each at 2% to 8% of the doses studied, and the evidence for them is weak even at full dose.
• The American Urological Association recommends that men with ED be told about prescription PDE5 inhibitors.

The page shows a 90-day guarantee, but the binding terms allow 10 days from purchase, for unused goods.

Our Dose Check compares each label amount with the best human study.

• L-arginine (daily): 750 mg vs 1,500 to 5,000 mg a day. Below the studied range.
• L-arginine ("Before"): 3,000 mg in one dose. Within the range, but the trials gave it daily, not before sex.
• Korean ginseng: 50 mg vs 2,700 mg a day. About 2%.
• Tribulus: 50 mg vs 800 mg a day, which did not work. About 6%.
• Maca: 50 mg vs 1,500 to 3,000 mg a day. About 2 to 3%.
• Fenugreek: 50 mg vs 600 mg a day of a different extract. About 8%.

Directions disagree. The sales page says to take "Before" two hours before sex; its FAQ says 30 minutes, and 4 to 6 capsules; NuviaLab says 6 capsules. The daily capsules are 1 twice a day before meals, with 300 ml of water.

Our Transparency Score checks five things a buyer can verify. Eron Plus scores 2 out of 5.

• Label with doses: yes. Full amounts on NuviaLab's store; the sales page itself shows none.
• Identifiable company: no. The Swiss site names Key Player Limited, Dubai Airport Freezone; the English site names only "EronPlus.com" in Hong Kong. The Swiss homepage's privacy notice even names a different website (memberxxl.ch). No manufacturer is named.
• Refund terms in writing: yes. 10 calendar days from purchase, unused goods only.
• Independent testing shown: no. The page says only that it was "developed at a renowned laboratory".
• Study on the finished product: no. The page mentions studies on maca and fenugreek without links or doses.

The sales page promises "longer sex by up to 30 minutes" and says both products "do not cause any side effects".

Correction. An earlier version of this review scored Eron Plus 9/10 and recommended it, said no amounts were published, benchmarked it against citrulline, and described GMP manufacture, a $41 price and free shipping. We have corrected it.

Prices when we checked in September 2026:

• Swiss site (where our link leads, in German): CHF 59.99 per set, CHF 119.98 for 3, CHF 179.97 for 6, plus CHF 9 shipping by card.
• German site: €49.99, plus €6. US: $59.99, plus $12. UK: £49.99, plus £14. NuviaLab: $62.99.

90 days or 10 days? The sales page shows a "90-day money back guarantee" banner. The binding terms allow withdrawal only "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. Switzerland gives no general legal right to return goods.

• Hidden drugs in this category: the FDA warns that sexual enhancement products are "likely to be contaminated with dangerous hidden ingredients" and that a product's absence from its list "does not mean it is safe". Eron Plus is not on the list.
• Arginine: side effects were more common than with placebo in the meta-analysis (8.3% vs 2.3%), none severe. The "Before" dose delivers 3 g at once.
• Ginseng might lower blood sugar and may interfere with blood clotting, according to the NCCIH.

There is no clinical study on Eron Plus itself.
