Product Information

Suggested use: General use is 1 to 4 tablets daily. Due to the stimulatory nature of this formula, start with 1 to 2 tablets per day to assess personal response. If desired, gradually increase over the course of two weeks based on comfort level. Do not exceed 4 tablets per day. Best if taken on an empty stomach, 1 hour prior to sexual activity. May be divided into separate dosage occasions; for example, twice per day.

Consult with your physician if you're taking any prescription medications or being treated for any medical condition.

Do not take if you have hypertension or cardiovascular condition, have diabetes or kidney disease, or suffer from anxiety or any psychiatric condition. Caffeine or pseudoephedrine may potentiate the stimulant effects of this formula. If side effects such as dizziness, nervousness, heart palpitations, or anxiety occur, decrease dosage. If side effects or any type of discomfort continues, discontinue use.

If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product.

🧪 Formulation Notes

Comprehensive male libido formula

Male Nitro is a comprehensive formula that supports multiple body systems for enhanced male sexual response. Systemic benefits include enhanced states of arousal, blood flow, nitric oxide (NO) production and endothelial health. Nitric oxide released by healthy endothelial cells stimulates dilation of blood vessels (vasodilatation) for healthy blood flow, essential for the male sexual response. Key ingredients for enhanced sexual function are yohimbine and arginine. Saw Palmetto, nettle, and zinc support a healthy prostate and genitourinary system.

Additional Information

Store in a cool, dry place.
