Member XXL Review: The Truth About the Size Claims

Member XXL is sold on penis enlargement, claiming increases of up to 9 cm, supported by an in house study. There is no credible scientific basis for an oral supplement enlarging the penis. The ingredients, L arginine, ginseng, tribulus and others, are ordinary circulation and libido herbs, and no doses are disclosed. We cannot recommend it on its central claim.

Value & full review

What Member XXL is

Member XXL is a capsule sold prominently on penis enlargement, with claims of growth of up to 9 cm backed by an in house study.

The claim does not stand up

There is no credible scientific basis for an oral supplement enlarging the penis. The study the brand cites is its own, not independent peer reviewed research, and the headline figures are not supported by mainstream medicine. This is the part to disregard entirely.

What the ingredients really are

Strip away the marketing and the formula is a familiar circulation and libido blend: L arginine, Korean ginseng, tribulus, fenugreek and saffron. At best, L arginine and ginseng may mildly support blood flow and firmer erections. That is not the same as changing size, and no doses are disclosed anyway.

How to use it, and when to see a doctor

It is two capsules a day. If your real concern is erectile function, see a doctor, since that can have medical causes a supplement will not address.

Our verdict

An ordinary circulation supplement sold on an extraordinary, unsupported claim. We cannot recommend Member XXL for enlargement, because that result is not real.
