Aizen Power is a two-capsule-a-day formula sold for erections through BuyGoods. Its label is public, but most actives were studied for blood sugar, several sit well below trial doses, and four hide in a blend. No trial tested the product. It costs $49 to $79 a bottle, with a 60-day refund that requires mailing every bottle back.

This Aizen Power review is built from the sales page, the refund and shipping policies, the Supplement Facts label the vendor posts, and the human research on each listed ingredient.[1][2][3][4] Nobody on our team took the capsules. We graded the evidence the way our how we review supplements page describes.
It is written for men weighing a $158 to $294 order for erection support who want to know what the label holds before they pay.

What is Aizen Power and what does the vendor claim?
Aizen Power is a capsule supplement sold to men for erection support. Each bottle holds 60 capsules, and the label serving is two a day, so a bottle lasts a month. The formula lists ten actives. No trial of the product has been published.[1][4]
The sales letter is signed by “Arnold P. Joyce”, described as a 47-year-old “medical researcher in a well-known clinic in Cleveland”. The clinic is never named, so we could not confirm the person. The letter calls the capsules “100% Effective” and “100% Safe”.[1]
Other pages push further. The FAQ says the herbs work “by activating the penis growth gene that every man has”. The reference list behind that idea cites mouse studies of the Sry sex-determination gene, which have nothing to do with adult penis size.[4][5]
The letter also says every capsule is made “in our FDA approved and GMP certified facility”. The vendor’s own FAQ admits that “the FDA is not authorized to review any dietary supplements”. The FDA does not approve supplement factories, and the FTC expects health claims to rest on solid trials of the product or a close match.[1][5][16]
The page carries scarcity lines too: stock “will run out”, and a restock would take “at least 8 months”. We treat those as sales copy.[1]
How is Aizen Power supposed to work?
The vendor gives two stories. The text letter says the plants and vitamins “support the health of your erections in a new and revolutionary way”. The FAQ says a gene is switched on so the penis grows. Neither comes with a study or a measured result.[1][5]
What is known about erections points elsewhere. NIDDK lists diabetes, heart and blood vessel disease and high blood pressure among the most common causes of erectile dysfunction (ED), along with some medicines and nerve damage.[6] A capsule cannot tell you which of those is behind your symptoms.
The label itself reads like a blood sugar formula. Berberine, chromium, alpha lipoic acid and banaba were mostly studied in people with type 2 diabetes. Since poor glucose control can harm the blood vessels and nerves involved in erections, that is the only plausible link we can draw, and nobody has tested it with this product.[4][6][10]
NIDDK advises men to talk with a clinician before using supplements for ED and not to order ED medicine online without that talk.[7] Its first-line advice is quitting smoking, eating well, moving more and keeping a healthy weight.
What ingredients are in Aizen Power?
The vendor posts a full Supplement Facts panel, which many sellers in this category do not. Six actives carry exact doses. Four more sit in a 112 mg proprietary blend, so their amounts are hidden. Other ingredients are gelatin, microcrystalline cellulose, magnesium stearate and silicon dioxide.[4]
| Ingredient | Label dose | Human evidence | Grade |
|---|---|---|---|
| Berberine HCl | 100 mg | Blood sugar trials at 900 to 1,500 mg a day[10] | Limited |
| Chromium picolinate | 100 mcg | Mixed results in diabetes trials[11] | Limited |
| Alpha lipoic acid | 150 mg | Glucose trials mostly near 600 mg a day[12] | Weak |
| Green tea extract | 150 mg | Small glucose effects; rare liver injury[13] | Weak |
| Resveratrol | 40 mg | Glucose effects only at 500 mg or more[14] | Weak |
| Zinc gluconate | 11 mg | Matches the daily value; no ED trial at this dose[4] | Weak |
| Blend: milk thistle, cayenne, ginseng, banaba | 112 mg total | Root ginseng has a trivial ED effect; the rest untested for ED[9][15] | Weak |
Berberine, chromium and alpha lipoic acid
A 2022 meta-analysis found berberine lowered fasting glucose and HbA1c in adults with type 2 diabetes. Those trials mostly gave 0.9 to 1.5 grams a day. Aizen Power has 100 mg, a small fraction of that, and none of the trials looked at erections.[4][10]
NIH’s Office of Dietary Supplements describes chromium trials in diabetes as mixed, and warns it may add to the effect of insulin and diabetes drugs.[11] Pooled trials of alpha lipoic acid showed lower fasting glucose and HbA1c, mostly at about 600 mg a day, four times the 150 mg here.[12]
Green tea, resveratrol and zinc
The green tea extract is standardized to 50% EGCG, so 150 mg holds roughly 75 mg of EGCG. NCCIH links concentrated green tea extracts to rare cases of liver injury and notes they carry caffeine.[13] A meta-analysis of 17 trials found resveratrol moved fasting glucose only at 500 mg a day or more; the label gives 40 mg.[14]
Zinc comes as 11 mg of zinc gluconate, which the label lists as 100% of the daily value. That is a typical multivitamin amount, and we found no erection trial at that dose.[4]
The 112 mg blend
Korean ginseng is the one ingredient here with erection research. A 2021 Cochrane review of 9 trials and 587 men found root ginseng had only a “trivial effect” on erectile function compared with placebo.[9] NCCIH notes the root is the part most used, and Aizen Power uses an aerial (leaf and stem) extract that has no ED trial we could find.[4][8]
Milk thistle may lower blood sugar in type 2 diabetes, per NCCIH.[15] Cayenne and banaba have no erection data. All four share 112 mg, so each gets far less than any studied dose.[4]

Does Aizen Power work for erections?
No study has tested Aizen Power for erections, size or anything else. The ingredient with the closest research, ginseng, showed a trivial effect in the Cochrane review, and that was root ginseng at doses far above what a 112 mg blend could hold. The rest were studied for blood sugar.[4][9]
The penis growth claim has no human support at all. The papers the vendor lists for it are mouse genetics studies about how male sex is set before birth.[4][5]
The vendor’s own FAQ says “tests have indicated that supplements take around 9-12 weeks to show results” and recommends at least three bottles. It names no test. A 9 to 12 week wait also runs past the 60-day refund window, which is worth noting before you pick a package.[2][5]
If erections have changed, NIDDK’s advice is a check-up first, since ED can be an early sign of diabetes or heart disease.[6] Proven ED medicines exist and have been tested in large trials. Some men will still want to try a supplement; on this evidence, expect little from it.
For comparison, we found the same gap in other male-health formulas we reviewed, such as Nitric Boost Ultra and FlowForce Max.
Aizen Power side effects: who should skip it?
The main risk comes from stacking. Berberine, chromium, alpha lipoic acid, milk thistle, ginseng and banaba can each nudge blood sugar down. Men on metformin, sulfonylureas or insulin could see an added drop, so a doctor should approve it first. The label’s own caution says to consult a physician if you take any medication.[4][8][10][11][15]
- NCCIH says Asian ginseng may interfere with blood clotting, which matters for men on warfarin.[8]
- Concentrated green tea extract has been linked to rare liver injury.[13]
- The green tea extract carries some caffeine, though the label gives no amount. Men sensitive to stimulants should know that.[4][13]
- Berberine and cayenne can cause cramps, reflux or loose stools in some people.[10]
- Insomnia is the most common side effect NCCIH lists for ginseng.[8]
Vegetarians should note a mismatch. The page shows a “Vegetarian” badge, yet the label lists “Gelatin (Vegetable Capsule)”, and gelatin usually comes from animals. Ask the vendor before you order if that matters to you.[1][4]
Men with heart disease or blood pressure drugs should talk to their doctor about ED in general, because the condition and some ED treatments interact with heart care.[6][7]

What is the Aizen Power price for each package?
Aizen Power costs $79, $69 or $49 a bottle depending on the package, with no single-bottle option. Two bottles cost $158 plus $9.99 shipping. Three cost $207 and six cost $294, both with free US shipping. Every order is a one-time payment with no subscription.[1]
Lowest price per bottle
6 bottles
$49 a bottle
$294 total, 180-day supply, free US shipping
The vendor calls the larger packages “2 + 1” and “3 + 3”, as if bottles were free. That framing is the seller’s: you pay $207 and $294. The crossed-out totals of $358, $537 and $1,074 are the vendor’s list prices, used to claim savings of $200, $330 and $780.[1]
At two capsules a day that works out to about $2.63, $2.30 or $1.63 a day, before shipping. Orders to Canada, the UK and Ireland, Australia and New Zealand pay $15.95 shipping.[3] The vendor’s product data also lists extra-bottle offers at $29 a bottle after checkout. Turn down any you did not plan to buy.[1]
To test it with the least money at risk, take the 2-bottle package, set a phone reminder about two weeks before day 60, and keep the form that ships in the box.
Does Aizen Power have a money-back guarantee?
Yes, for 60 days counted from the date your order ships. To get a refund you mail every bottle back to a warehouse in Aurora, Colorado, at your own cost, with the Return and Refund Form from the box. The vendor says the refund follows “in only a few days” after it arrives.[2]
The refund policy lists four steps:[2]
- Check that you are still inside 60 days from the ship date, shown on the package and in the shipping email.
- Fill in the Return and Refund Form that came with the order.
- Send all the bottles to 19655 E 35th Dr #100, Aurora, CO 80011, USA.
- Wait for the email confirming the refund.
“We do not support the return shipping costs,” the policy says, and it requires “ALL the supplement bottles”. A parcel mailed on day 59 still counts. The sales letter, by contrast, says to “contact us in the first 60 days from your purchase”. Go by the stricter written policy and write to contact@getaizenpower24.com before you ship.[1][2]
Where to buy Aizen Power?
Buy only from the vendor site, aizenpower101.com, where BuyGoods runs the checkout and the 60-day refund applies. The letter says the formula “is not available for purchase anywhere else”. Bottles from marketplaces or lookalike pages may not be covered by the refund, and some copycat sites quote other prices.[1]
The US shipping page promises a tracking email within 60 hours and delivery in 5 to 7 working days. Order questions go to BuyGoods, and product questions to the email above. No phone number is published.[2][3]

What do Aizen Power reviews and complaints show?
We found no independent customer data we could read. The sales pages show testimonials marked “Verified Purchase” without saying where they were verified, and the site’s disclaimer says they “may not reflect the typical purchaser’s experience”. We did not count them as evidence.[1]
Trustpilot blocked our reader and has no archived copy, and BBB results did not load, so we cannot report ratings or complaint counts from either. If you look yourself, check whether a review names the vendor site or a copycat.
The facts we can confirm are on paper: a posted label, a named retailer, a one-time payment, and a written 60-day policy with a return address. Those are reasonable signs. The weak spots are the growth claims, the FDA wording and the persona nobody can verify.[1][2][4][5]
Who is Aizen Power best for?
Aizen Power may suit a man who has seen a doctor, knows his blood sugar and heart health, takes no glucose-lowering or blood-thinning drugs, and wants to try a low-dose ingredient mix with the refund as a backstop. It does not fit men looking for size gains or a proven ED treatment, or anyone on diabetes medicine.[4][6][9]
If you order, read the label on the bottle when it arrives and mark the 60-day deadline from the ship date. The full label counts in its favor, though nobody has tested the formula itself.[2][4]
Are there cheaper evidence-based alternatives?
A doctor’s visit can turn up diabetes, high blood pressure or a medicine side effect, and treating those often helps erections. The ED medicines NIDDK describes have large trials behind them. Quitting smoking and more activity also help, per NIDDK.[6][7]
If blood sugar is your real concern, we looked at the tea-based options in our Gluco Cleanse Tea review. For urinary symptoms in older men, see our Prosta Peak review.

Frequently asked questions
Where can I buy Aizen Power?
Buy it on aizenpower101.com, where BuyGoods handles payment and the 60-day refund applies. Prices run from $49 to $79 a bottle, and three or six bottles ship free in the US. Bottles from marketplaces or copycat pages may fall outside the refund.
Does Aizen Power have a money-back guarantee?
Yes. You have 60 days from the ship date to mail every bottle, empty or full, to the Aurora, Colorado warehouse with the Return and Refund Form. You pay the return postage, and the vendor says it refunds within a few days of receipt.
What are the Aizen Power side effects?
No side effects were reported for the product itself because it has no trials. Its ingredients can lower blood sugar, ginseng may affect clotting and sleep, green tea extract carries caffeine and rare liver risk, and berberine can upset the stomach. Ask a doctor first if you take medicine.
How do you take Aizen Power?
The label says two capsules a day with water. The vendor FAQ suggests one capsule twice daily, 10 to 15 minutes before a meal, so one bottle of 60 capsules lasts a month. Do not take more than the label serving.
How long before results, per the vendor?
The vendor FAQ says supplements take around 9 to 12 weeks to show results, without naming any test. That wait runs past the 60-day refund window, so plan your return date before you start and decide by about week seven.
Is Aizen Power legit?
It is a real product with a posted label, a BuyGoods checkout, a one-time payment and a written 60-day refund policy. Its growth and FDA claims are not supported, the founder persona cannot be verified, and the formula has never been tested in a trial.
