Frequently Asked Questions

Circumcision. It’s not an issue we talk about a lot. Maybe because we take it for granted. Or perhaps we’re embarrassed. The fact is, American men are different – we’ve lost important skin and nerve tissue that are important in triggering orgasm. Many of us have dull ‘members’ and may have difficulty achieving the levels of excruciating, raw pleasure that other men experience.

CIRCUMserum™ is a moisturizing therapy that softens and conditions the glans (head of the penis), enabling men to feel more intense sensation during sex.

  • Who Should Use CIRCUMserum™?

    In surveys of sample groups, CIRCUMserum has been established to increase the intensity of a man’s sexual pleasure with regular use.

    Most circumcised men can benefit from regular use of CIRCUMserum to improve their satisfaction.

    *How Do I Use CIRCUMserum?

    Using CIRCUMserum’s special handheld pump, simply apply a small amount of cream and massage it into the skin of the glans (head of penis). Allow to air dry. Wash hands with soap and water.

  • What Will I Feel When I Use CIRCUMserum™?

    You will feel a slight, pleasurable tingling when first applied. After several minutes, this feeling will fade, and you will notice a softening of the skin as you use CIRCUMserum™ regularly.

  • What Ingredients are in CIRCUMserum™?

    Essential oils and natural botanicals are the primary ingredients in CIRCUMserum. These are gentle, natural substances, including rose oil, sweet almond oil, cinnamon bark oil, and other premium-quality, pure-sourced extracts.

  • Are the Ingredients Safe?

    Ingredients in CIRCUMserum are listed by the US Food and Drug Administration (FDA) as GRAS – “Generally Recognized as Safe.” The GRAS list covers common food and food additives approved for human consumption. CIRCUMserum contains NO drug ingredients.

    Since CIRCUMserum is applied as a cream, there are no pills to take and you don’t have to worry about putting any unknown substances in your body.

    To ensure quality and consistency in every bottle, CIRCUMserum is produced following GMP (Good Manufacturing Practices) guidelines in an FDA-registered facility.

  • Can Uncircumcised Men Use CIRCUMserum™?

    Uncircumcised men should not use CIRCUMserum.

  • How was CIRCUMserum™ Developed?

    In response to increasing awareness about the important role of masculine sensitivity in sexual function, CIRCUMserum was developed by leading pharmacists in the field of male sexual function. Centric Research Institute’s scientific team formulated the first topically-applied Erectile Dysfunction treatment, in addition to a wide range of other popular and effective health and beauty products.

    CIRCUMserum’s patent-pending formula (#CRI-44) is the result of years of research into the optimal combination of natural oils to condition the skin of the glans and provide just the right amount of biofeedback for a majority of men.

    *How is CIRCUMserum Packaged?

    CIRCUMserum is packaged in a sleek, convenient handheld pump that dispenses 150mg of cream with each push of the button. Most men find that 1-2 pumps is sufficient for each application.
