Questions
Straight answers.
How do I take SEMEX?
Three capsules a day with water, ideally with a meal. Use it consistently for at least two to three weeks before you judge it.
What does SEMEX do?
SEMEX is a daily formula of ten actives studied to support seminal fluid production, libido, healthy blood flow and male reproductive health. Volume and taste are what most men notice first.
Will it taste better?
Bromelain, the enzyme from pineapple, and maca are in the formula for that reason, to support a cleaner, sweeter result over time. Diet still matters.
How long until I notice something?
Most men report the first changes within two weeks and a clearer difference by day 30. Give it a full month.
Is SEMEX safe?
SEMEX is manufactured in an NSF cGMP registered facility in the USA and third-party tested by Eurofins. It is hormone-free, non-GMO and vegan. If you take medication or have a medical condition, ask your doctor first.
Does SEMEX support reproductive health?
Zinc, maca, tongkat ali and ashwagandha are each studied for aspects of male reproductive health, including sperm parameters and healthy testosterone levels. SEMEX is not a treatment for infertility or any medical condition.
What if it doesn't work for me?
Request a refund within 90 days of your first delivery and we refund the full product cost. No questions asked.
