Hello,
Thank you for asking the query.

Nitroxpansion advertise itself to be a sexual enhancement product. They claim to increase sexual performance, build muscles and enhance penis length. So should you take it for any of the above mentioned purpose?

I would say No. The reasons being:

1. This is not clinically proven. Unlike the medications out there, this is not tried, tested, proven or FDA approved.  There is very less chance that it will ‘work’ – that is give you any of the above said desired benefits.

2. Possible side effects: They don't explicitly mention the contents. Most of the  'enhancement' products can contain anabolic steroids, which can build up muscles in the short term, but can decrease the sexual performance in the long term. There might not be major and readily appreciable side effects, but still it’s better to stay safe 

3. Waste of resources and time.

Since you are young, you should focus on nutritious diet and physical exercise. If you have any specific health queries, please feel free to ask.
Thank you.
