Nitro Wood™ Magnum Review 2026: Misleading Claims
Skip this one. — Misleading
-
"BlackVCube dosed at 90mg matches the clinical study dose"
The label amount lines up with the dose used in the single published trial, unlike many underdosed competitor products.
-
"Clinically shown to increase male size (girth and length)"
The only cited study is PMID 21884777, a 45-man, 2011 trial never replicated in a larger or independent trial since.
PubMed: Kongsui et al 2011 (PMID 21884777) -
"No proprietary blends hiding underdosed ingredients (per FAQ)"
The label lists a 'Blood Vessel Expansion Blend' combining four ingredients with only a total weight, not individual doses.
-
"Works better than pharma ED drugs like PDE5 inhibitors"
No clinical trial compares this product to sildenafil or tadalafil; the claim has no direct supporting evidence.
Consumer advice
The BlackVCube dose (90mg) is dosed to match the cited study, so credit where due — but that study is old, small, and not independently replicated, so treat the "increase length and girth" claim skeptically. The "Blood Vessel Expansion Blend" hides individual doses of beetroot, cinnamon, garlic, and cayenne, so you can't verify any of them hit clinically effective amounts. If you want the actual evidence-backed benefit (better circulation), a cheap beetroot powder or L-citrulline plus a doctor conversation about actual ED treatment will likely do more for less money. Watch the subscription: it auto-renews and pushes you toward 3-6 bottle "welcome kits" with upsells layered in.

Safety & side effects
What NIH says about the ingredients in this product. This describes the ingredients, not tests of this product, and it is not medical advice. Ask a doctor or pharmacist first if you take medication, are pregnant or nursing, or have a health condition.
Grape Seed Extract
NCCIH says grape seed extract is generally well tolerated when taken by mouth or used on the skin. It advises talking with a health care provider if you take any medicine, and says little is known about use during pregnancy or breastfeeding.
Avoid or ask a doctor first if
- Little is known about whether grape seed extract is safe during pregnancy or breastfeeding.
Medication interactions
- People who take any medicine should talk with a health care provider before using grape seed extract, because some herbs and medicines interact in harmful ways.

Cinnamon
NCCIH says cinnamon is likely safe in the amounts commonly used in foods. Larger amounts or long-term use are sometimes linked to side effects, mostly gastrointestinal problems or allergic reactions.
Possible side effects
- Larger amounts or long-term use are sometimes linked to gastrointestinal problems or allergic reactions.
- Topical cinnamon oil or powder may cause skin irritation or contact dermatitis, according to reports.
Serious risks
- Interactions between coumarin, a chemical in cassia cinnamon, and the liver have been reported.
- Swallowing cinnamon powder in the "cinnamon challenge" is called unsafe, and serious harm is possible.
Avoid or ask a doctor first if
- Ceylon cinnamon in larger amounts during pregnancy is considered unsafe.
- Prolonged use of cassia cinnamon could be an issue for sensitive people, such as those with liver disease.
Medication interactions
- Some components of cinnamon may interact with an anticancer medicine or nicotine, for theoretical reasons.
Garlic
Garlic taken orally has been used safely in studies lasting as long as 7 years, but supplements may raise bleeding risk. Fresh raw garlic on the skin can cause severe irritation and chemical burns.
Possible side effects
- Oral garlic can cause breath and body odor, abdominal pain, flatulence, and nausea.
- Some people have allergic reactions to garlic.
Serious risks
- Garlic supplements may increase the risk of bleeding.
- Fresh raw garlic used topically can cause severe skin irritation and chemical burns.
Avoid or ask a doctor first if
- Garlic taken orally in amounts greater than those in foods may not be safe during pregnancy or breastfeeding.
- People having surgery are told to let their providers know they take garlic supplements.
Medication interactions
- If you take garlic supplements, tell your health care providers. This matters most before surgery or if you take medicines like anticoagulants or aspirin that may also affect bleeding.
- If you take anticoagulants, aspirin, or any other medicine, talk with your health care provider before using garlic or other herbal products, because some herbs and medicines interact in harmful ways.
