Semapro vs. Popstar Labs

Semapro vs. Popstar Labs for Semen Volume

Written by: Dr. Brian Steixner

The Semen Volume Supplement Debate

Many supplements claim to enhance different aspects of sexual performance. One such category of supplements focuses on semen volume, aiming to increase the amount of semen produced during ejaculation. Two such supplements available on Amazon are Popstar Labs and Semapro. Both claim to support semen volume, but we believe Popstar Labs offers additional benefits, such as improving semen taste and promoting overall semen health. Below, we compare the two products to help you make an informed decision about your best choice.

Semapro Review

Semapro, available on Amazon, contains numerous ingredients aimed at enhancing semen volume. However, we have several concerns regarding the efficacy of many of those ingredients and Semapro’s ingredients lacking peer-reviewed “scientific” evidence of their ability to increase semen volume.


While Semapro provides the recommended amount of Zinc (50mg) for maximum impact on semen volume, most of its other ingredients have not been scientifically shown to contribute significantly to semen volume. Ingredients such as Mucuna Pruriens Seed Powder, Saw Palmetto Berry Powder, Panax Ginseng Root Powder, L-Lysine HCL, and Polypodium Vulgare Herb Powder have not been proven to increase semen volume and may even cause unwanted side effects.


Moreover, Semapro, and its parent company Male FX Labs, has received FDA concerns, and previous products have been deemed unsafe by the FDA. Additionally, the fact that Semapro is being sold under a different name, Semanoid, with identical ingredients and packaging but without clear manufacturing or quality assurance information is something to be concerned about. Semapro, as far as we can tell, also does not have a website or contact information.

Semapro vs. Popstar Labs

Popstar Labs Review

Unlike Semapro, Popstar Labs, which was founded by two Ivy League-trained sexual health doctors, proudly displays all of its ingredients, has contact information on its website, and contains only ingredients that have been scientifically reviewed and shown as having the potential to increase semen volume and taste. Developed initially for our patients and rooted in clinical science, Popstar Labs has endeavored to set a new standard in semen health supplements. Manufactured in the USA in an FDA-registered facility, Popstar Labs ensures the highest quality standards. It is non-GMO, fair trade, vegan, and third-party tested, guaranteeing its safety and efficacy.


Zinc, an essential nutrient for semen volume, is the primary ingredient in Popstar Labs. Each serving provides 50mg, significantly higher than other products on the market. This dosage is based on medical literature for optimal effects, as Zinc has been shown to significantly increase semen volume and sperm health. Recently, Popstar Labs added 4mg of Copper to its formula, further enhancing its effectiveness in maximizing semen volume while minimizing side effects.


Popstar Labs contains 1200mg of Lecithin, derived from sunflowers, which is associated with larger semen loads. Additionally, it provides 800mg of L-arginine, a crucial nutrient for semen volume enhancement. These dosages are based on recent scientific studies, ensuring maximum benefits.


Furthermore, Popstar Labs includes 200mg of Pygeum, another essential nutrient for semen volume and ejaculation enhancement, and 400mg of Bromelain, which is excellent for improving semen taste and enhancing overall semen and sperm quality. Popstar Labs was the first supplement to focus on total semen health, addressing volume, taste, and fertility.

Bottom Line

Given the fact that Semapro and Semanoid do not contain many of the ingredients we have listed above, and given the lack of contact information for both companies and their parent company’s history of FDA issues, we strongly advise choosing Popstar Labs, with its doctor-formulated supplement, instead of Semapro or Semanoid. Popstar remains the top choice on Amazon for semen volume enhancement because of our focus on sexual health, wellness, and efficacy.
