What Is in ErecPower? The Six Botanicals on the Label
The ErecPower label names six botanicals in each capsule.
They are hawthorn berry, tribulus, chrysin, epimedium, saw palmetto and tongkat ali. This page lists each name next to the dose published trials used.
Then see how to take ErecPower each day.
Six names, one repeated phrase, and the amounts every published trial ran on. The middle column of the table below is the most important thing on this website.
The ErecPower panel, exactly as published
| Botanical | Amount per capsule | What published trials used |
|---|---|---|
| Hawthorn Berry | not published | 160 to 1,800 mg a day of a standardised leaf-and-flower extract |
| Tribulus | not published | 750 to 1,500 mg a day in the published trials |
| Chrysin | not published | 3 mg per kilogram a day for 21 days, in the one human study |
| Epimedium | not published | no established human dose; the icariin work is laboratory work |
| Saw Palmetto | not published | 320 mg a day of the lipidosterolic extract |
| Tongkat Ali | not published | 100 to 600 mg a day of a standardised root extract |
A Supplement Facts panel is legally required on the physical bottle. It is not reproduced in the manufacturer's listing artwork and it is not in the material this desk holds, so the middle column is not an omission on our side. If your bottle carries one with numbers on it, photograph it and send it to [email protected] and this page will be corrected.
Every ErecPower botanical, and what it is actually for
Five of the six have a published human trial record. One of them has a trial record that says it does nothing, and we have put that card in the same size type as the rest.
Hawthorn Berry
Crataegus, the fruit · amount per capsule: not publishedThe fruit of a thorny hedgerow shrub, used in European herbal medicine for the heart rather than for anything sexual. Its measurable constituents are oligomeric procyanidins and flavonoids. It is the one item on this panel with a substantial controlled trial record, and that record is about chronic heart failure, not about stamina or circulation in a healthy man. It also carries the clearest drug interaction on the label.
What the research used. 160 to 1,800 mg a day of a standardised leaf-and-flower extract. the Cochrane review of hawthorn extract is the record this desk works from. Set that beside the middle column of the table above and the difficulty is plain: there is nothing on this label to compare it with.
Tribulus
Tribulus terrestris, the aerial parts · amount per capsule: not publishedA low creeping weed whose reputation in supplements rests on steroidal saponins, usually standardised to protodioscin. It is the most tested ingredient in this category and the results split sharply: the hormone studies are largely negative and the sexual function studies are mixed. It is the panel item whose reputation most outruns its evidence.
What the research used. 750 to 1,500 mg a day in the published trials. Kamenov 2017, the largest tribulus trial is the record this desk works from. Set that beside the middle column of the table above and the difficulty is plain: there is nothing on this label to compare it with.
Chrysin
5,7-dihydroxyflavone, a flavone · amount per capsule: not publishedA flavone found in passionflower, honey and propolis. It inhibits the aromatase enzyme in a test tube, which is why it appears in products aimed at testosterone. In a human being almost none of an oral dose survives first-pass metabolism in the gut wall and the liver, and the one published human trial found no change. It is the weakest item on this panel and this website says so on every page it appears.
What the research used. 3 mg per kilogram a day for 21 days, in the one human study. the one published human chrysin trial is the record this desk works from. Set that beside the middle column of the table above and the difficulty is plain: there is nothing on this label to compare it with.
Epimedium
Epimedium species, the leaf · amount per capsule: not publishedBetter known as horny goat weed. Its named constituent is icariin, a prenylated flavonoid that inhibits PDE5 in laboratory assays, which is the same enzyme family a prescription erectile dysfunction drug acts on. The laboratory potency is a small fraction of the drug's, and the human trial record for the herb itself is close to empty.
What the research used. no established human dose; the icariin work is laboratory work. the 2026 Epimedium review is the record this desk works from. Set that beside the middle column of the table above and the difficulty is plain: there is nothing on this label to compare it with.
Saw Palmetto
Serenoa repens, the berry · amount per capsule: not publishedA small palm from the south-eastern United States. Its extract is one of the most studied botanicals in men's health, and the studies are about the prostate and urinary flow rather than about sex. The Cochrane review is the reason it is on this page at all, and the reason the safety page carries a note about PSA testing.
What the research used. 320 mg a day of the lipidosterolic extract. the updated Cochrane review of saw palmetto is the record this desk works from. Set that beside the middle column of the table above and the difficulty is plain: there is nothing on this label to compare it with.
Tongkat Ali
Eurycoma longifolia, the root · amount per capsule: not publishedA Southeast Asian root, sold as a water extract standardised to eurycomanone. It has the most credible testosterone evidence on this panel: a 2022 meta-analysis of clinical trials found a measurable rise in serum total testosterone in men. Every one of those trials used a stated daily dose, and this label publishes none, which is the whole difficulty with reading that finding onto this capsule.
What the research used. 100 to 600 mg a day of a standardised root extract. the 2022 meta-analysis of tongkat ali trials is the record this desk works from. Set that beside the middle column of the table above and the difficulty is plain: there is nothing on this label to compare it with.
Grading the six ErecPower names on evidence, not on reputation
| Botanical | Human trial record | What it is actually studied for | Reads across to this capsule? |
|---|---|---|---|
| Tongkat ali | Strongest on this panel | Serum total testosterone in men | No. No dose is printed. |
| Saw palmetto | Large, and mostly negative for its own use case | Urinary symptoms of an enlarged prostate | No. No dose is printed. |
| Hawthorn | Substantial, in the wrong organ | Chronic heart failure | No. No dose is printed. |
| Tribulus | Mixed, and negative on hormones | Sexual function scores, androgen production | No. No dose is printed. |
| Epimedium | Close to absent for the herb itself | Laboratory PDE5 inhibition by icariin | No. No dose is printed. |
| Chrysin | One human study, which found nothing | Aromatase inhibition in a test tube | No. No dose is printed. |
The right-hand column is the same sentence six times, and that is the finding. A grade is only useful when there is a number to attach it to.
What “not published” actually costs a ErecPower buyer
It is legal. A manufacturer may declare a proprietary blend and print one total, or in practice print rather less than that, and many do. So this is not an accusation. It is a description of what you can and cannot learn from this bottle.
Three things become impossible at once. You cannot tell whether the tongkat ali in this capsule is anywhere near the 100 to 600 mg the 2022 meta-analysis pooled. You cannot tell whether the saw palmetto is near the 320 mg the Cochrane review used. And you cannot tell whether the six together would even fit: a standard size-0 vegetable capsule holds roughly 400 to 500 mg of plant powder, and the trial doses above add to well over three grams a day between them. We worked that arithmetic out in full in this article.
What you can still do is judge the product on the things that are disclosed: the format, the routine, the guarantee, the lot number, and this desk's own order record. Those are all real and all checkable, and they are what the reviews page and the batch page are for. The NIH Office of Dietary Supplements factsheet is the neutral account of what a Supplement Facts panel is supposed to carry, and it is worth reading once against this one.
The one thing to carry away. Every research figure quoted on this website belongs to an ingredient at a stated dose, never to ErecPower. The finished capsule has never been the subject of a clinical trial of its own, and neither has any product in this batch. NCCIH has a plain guide to telling those two kinds of statement apart.
What is not in ErecPower, which is also worth knowing
- ■No caffeine and no stimulant. Nothing on this panel is a stimulant, and nothing on it should keep you awake.
- ■No yohimbe. The most common problem ingredient in this category is not on this label, which is worth saying plainly.
- ■No hormone. There is no DHEA, no pregnenolone and no synthetic androgen named anywhere on the label or the artwork.
- ■No prescription drug, as far as the label goes. Tucker 2018 analysed the FDA's own warning record and found unapproved pharmaceutical ingredients in supplements sold for sexual enhancement. That is a category-wide finding rather than one about this product, and the answer to it is a traceable lot from a desk that answers the phone.
- ■No published Supplement Facts panel. Said once more, because it is the thing a summary of this page would otherwise leave out.
How this ErecPower ingredients page was put together
Every name on this page came off the printed label and the manufacturer’s own listing artwork. Every dose in the right-hand column came from the paper linked beside it, and every one of those papers was confirmed against its PubMed record before it was written down. Nothing in the middle column is estimated, because estimating it is the exact error this page exists to avoid.
Every page, every journal post, the bottle facts and the ingredients go through review by Dr. Goldwyn Foggie (Dr. Goldie), MD before they ship. We write these pages from the printed ErecPower bottle, the manufacturer’s own listing artwork and this desk’s stock paperwork for lot ERE-26/ER-5284. We cite public research for hawthorn, tribulus, chrysin, epimedium, saw palmetto and tongkat ali, and we print “not published” wherever a figure is not disclosed rather than estimating it. This label publishes no amount for any of its six botanicals, and that fact appears on every page where an ingredient is named. Where the seller’s marketing claims more than the bottle supports, we say so on the page. Corrections are made on the page itself and the review date moves forward. Write to [email protected]. Last reviewed September 2026 by Dr. Goldwyn Foggie (Dr. Goldie), MD.
