Frequently Asked Questions

At What Age Should You Consider Test+?  

Test+ is ideal for men 18 years and above who want to enhance their testosterone production through safe and natural means.

What is the recommended dosage for Test+?

Take 3 capsules daily, with food.

Should You Cycle Off Test+?

Is Test+ Recommended for Seniors?

As men get older, it's common for hormone levels, including testosterone, to gradually decrease. Maintaining healthy testosterone levels is essential for various aspects of well-being, including sexual health, cognitive function, weight management, mood regulation, and metabolic support. This product features several potent ingredients, one being the patented ingredient Tesnor®, a unique blend of pomegranate peel and cocoa seed extracts, which has been shown to help support both total and free testosterone levels.

What is Free Testosterone?

Free testosterone is the portion of testosterone in the bloodstream that is not bound to proteins, such as sex hormone-binding globulin (SHBG) or albumin. Unlike bound testosterone, which is attached to these proteins, free testosterone is biologically active and readily available for the body to use. It plays a crucial role in various physiological functions, including muscle growth, sexual function, mood regulation, energy levels, and overall well-being.

Since free testosterone is the active form, its levels are often a key indicator of how effectively testosterone is functioning in the body, even if total testosterone levels appear normal. Monitoring free testosterone is important, especially for assessing hormonal health in men as they age.

How soon will I notice results?

Individual results may vary, but we typically recommend using Test+ consistently for 8-12 weeks.

Natural Engaged Energy

I started taking this supplement to improve my energy, drive, and strength. After about 2 weeks, I'd say, I felt a difference, especially with my drive working out. It's that no quit urge, right wanna give up!

I juts received the zendurnace order and have 4 days of use. So far the results are good and want more time to evaluate.

Great product so far, I have been taking Test+ for about a month now and I already feel some noticeable improvements in my energy levels throughout the day, I don't feel the mid day fog that I used to get. I am also now able to keep my intensity level up much higher during my entire workout. Again great product so far.
