  • Sleep Inducer and Relaxation for Optimal Rejuvenation
  • Enhance Muscle Recovery
  • Increase Lean Muscle Growth

Nighttime is often an overlooked and underutilized time for nutritional health. But it does offer a profound opportunity to strongly reinforce and support your daytime supplementation. Think about it… supporting your health and continuing to progress forward toward your fitness goals while you sleep. That’s precisely what Core Active’s REM TEST is all about.

REM TEST is a nighttime sleep-inducing and testosterone-boosting formula that works through three distinctive pathways. First, it includes its TEST Charge Blend, which helps increase the body’s natural testosterone levels while blocking estrogen. Second, REM TEST’s REM Sleep Blend includes ingredients that promote a more restful, restorative sleep. And third, when deep in that relaxed state of sleep, its Growth Factor + Estrogen Blocking Blend help to aid muscle recovery, build lean muscle tissue, and support lean body definition.

REM TEST’s highly versatile formula can be used as the perfect PCT (Post Cycle Therapy) after an intense on-cycle; it can be used alone at night to help with recovery and to facilitate lean muscle growth; and it can be used in tandem with any testosterone supplement used during the daytime toward maximizing your health and fitness goals. With REM TEST you gain the ability to drive results while you sleep!

Increase Testosterone and Boost Libido

REM TEST helps support an increase in testosterone and drives libido in a variety of ways. First, it will help you get a better night’s rest, which can ensure your testosterone levels won’t be negatively impacted by lack of sleep. A recent study funded by the National Heart, Lung, and Blood Institute found testosterone levels dropped significantly in men who don’t get enough sleep—equivalent to aging 10-15 years. Second, it includes Tribulus Terrestris, an herb that has been used for centuries for a variety of conditions including sexual function and testosterone production. REM TEST also includes Avena sativa, another herb long known for its ability to exert its benefits by freeing up “bound” testosterone. Over 95% of testosterone in men is bound to a couple of different hormones and can’t actually be used. Avena sativa can also help your body produce more luteinizing hormone (LH), which signals your body to produce more testosterone. And because REM TEST helps to boost testosterone levels at night, the result is a better version of you the next day!

Better More Restorative Sleep

REM TEST contains a strong set of herbal ingredients that helps make 4 hours feel like 6 and 6 hours of sleep feel like 8. It includes 3 mg of Melatonin, which helps signal the body that it’s time to sleep or when it’s time to wake up. Melatonin helps maintain our Circadian Rhythm, which is the built-in 24-Hour “clock” inside our body. By increasing melatonin production in the evening, Z-TEST will help make it easier to fall asleep. L-Theanine is included because of its ability to help relieve stress and induce a relaxing effect. L-Theanine also helps reduce mental and physical stress, improves focus and concentration, and enhances mood. 5-HTP is a naturally occurring amino acid and chemical precursor as well as metabolic intermediate in the biosynthesis of the neurotransmitters serotonin and melatonin from tryptophan. 5-HTP supports appetite suppression, and it’s beneficial to help aid sleep. This quality blend of ingredients helps make REM TEST a go-to solution for supporting a more restful sleep.

Estrogen Suppression

Whenever men raise testosterone production, their estrogen production likes to increase as well, which can have some less than desirable side effects. REM TEST contains three different estrogen regulators a part of its Growth Factor + Estrogen Blocking Blend. Indole-3-carbinol (I3C) occurs naturally in cruciferous vegetables such as broccoli, cabbage, cauliflower, Brussels sprouts, collard greens and kale. With powerful antioxidant protection, I3C helps to prevent cellular damage caused by free radicals. In addition I3C can help reduce estrogen levels while maintaining a healthy hormonal balance. DIM is an ingredient that helps block estrogen receptor activity, and by interfering with them, it helps raise the ratio of testosterone to estrogen. With DIM causing more testosterone to be freed, the resulting effects are a higher sex drive, enhanced mood, lean muscle building, and a greater sense of vitality and vigor. And believed to be an effective aromatase inhibitor, Chrysin supports decreasing your body’s level of estrogen. It has also been shown to induce an anti-inflammatory effect.

Stronger, and with Lean Muscle

REM TEST’s formula helps increase production with two major muscle-building hormones: testosterone and growth hormone. Testosterone is man’s best friend, and is considered the king of all muscle-building hormones because it’s primarily responsible for the growth of many bodily tissues that are essential for health and wellbeing. Growth hormone, which stimulates growth, cell reproduction and the release of insulin-like growth factor (to boost protein synthesis), is an integral part of the body’s process to help boost metabolism, burn fat and safeguard against muscle loss. When supporting both of these hormones together, REM TEST helps to set the foundational stage toward building lean muscle and supporting a stronger body definition.

What is REM TEST Used For?

Use REM TEST at nighttime to help suppress estrogen levels and boost natural testosterone production. It works by helping to put your body into a deeper, more restful state of sleep, and then actively disperses the rest of its ingredients throughout your body to help drive and increase your testosterone levels naturally. By supporting a deeper sleep REM TEST can help make 4 hours of sleep feel like 6, and 6 hours of sleep feel like 8. This is beneficial because more sleep allows for a greater sense of rejuvenation and recovery.

Directions For Use

Take 3 REM TEST™ capsules before bedtime on an empty stomach. Do not consume with milk or dairy (blocks bioavailability). To be used as part of a healthy lifestyle consisting of regular physical activity and a proper diet, or a part of a physical conditioning program.

Core Active REM TEST

Very good especially for the money. I think ZMA is a very good and proven supplement. This takes ZMA and adds other solid ingredients for good results.

Core Active REM TEST

So far I really like this supplement, it helps me fall asleep and I can tell a difference at the gym. I’ve been taking the serving size of 3 pills every night about 30 minutes before I want to go to sleep. I will definitely keep buying these.
