Overpower by Rohtos was recommended to me by a fellow competitior within CrossFit. After 2 months now trying out Overpower I must say that this gives me more energy to boost my training and therefore better results. It seems like I am recovering faster and ready for the next hard workout without any problems. The blood test also shows positive trends after only a few weeks. Excited to keep using this and to take new blood tests to support the feeling I have by using OP. Thank you Rothos! Eirik

I have been using Overpower now over 10 months and I could not be any more satisfied. I have experienced increased mental stamina, decision- and initiation making and mood. This has been very significant, because I started usage during the most challenging period of my life, and I was able to overcome all the diffuculties during one winter. I am fitness enthusiast, over 45 yrs, and even though I have not been able to keep my normal gym routines, I still have kept my fat% quite low and experienced higher-than normal trainability and recovery. Moreover, the most remarkable effect of OP have actualized on male behaviour (libido, competitiveness etc) and I would warmly recommend any 40+ men to feel like 30’s again. While using OP that long time, I recognized that Your own hormonal system was not turned off - all functions was back to normal during wash-out periodes. Also, I found personally suitable cycling of the two (alpha+omega) components. I am using alpha quite tonically 2 or 3 capsules/d and i cycle omega on/off of 7 days cycles. I have a hunch that omega is dealing with Your brains’ monoaminepathways (like dopamine and serotonine) and suitable dosage should be tailored by subjective testing. I highly recommed anyone to try OP, it will not be more that 3-5 days of usage and you will understand what I mean.

I just started my second patch of Overpower from Rohtos Labs. What I discovered during the first try, was that what Overpower significantly aided my recovery after each workout session, so I have decided to try a second patch with higher training frequency and heavier weights to maximise the benefits of the faster recover. I also previously tried Shield and would agree with Pekka Koski's review and add that both Overpower and Shield have clearly been designed with not just high quality ingredients, but also a sufficient amount of them which I think is very important in achieving the desired impact (for reference, I am a circa 40 year old male, 183 centimetres tall and approximately 98 kilos with muscular build). I have found all the Rohtos Labs products I have tried to be of excellent quality and would highly recommend them.


Allround Support

Overpower is designed to help maintain stamina and endurance under heavy strain by optimizing stress responses in all active organ systems – muscular, nervous, circulatory, endocrine and respiratory.

Overpower’s 100% natural formulation contains a blend of 10 herbal compounds. All ingredients are nutraceutical-grade extracts of the highest quality.

Overpower contains extracts of five of the best, science-proven performance-supporting adaptogenic herbs: Ashwagandha, Eleuthero, Cordyceps militaris, Ginseng and Rhodiola rosea. They are complemented by five other natural ingredients such as Shilajit and Mucuna bean to augment the adaptogenic effect and to supply crucial micronutrients into active tissues.

Adaptogens enable the body to withstand more physical stress and sustain activity by adapting the functioning of stressed organ systems. They accelerate the production and release of certain hormones and proteins – and decelerate it for others. They increase the rates of oxygen, protein, fat and carbohydrate utilization. They modulate key physiological parameters such as the resting heart rate and the respiratory rate.

Using multiple adaptogens simultaneously boosts and extends their effect, resulting in allround performance support.

Due to its nature, Overpower is highly versatile. It is being used across a range of activities – resistance training, ultra endurance activities, HIIT, combat sports, recovery from overtraining, lowering base heart rates and more.

On lactic acid buildup

Once lactate threshold is breached, lactic acid buildup causes fatigue and soreness. Three adaptogens in Overpower – Cordyceps, Ashwagandha and Eleuthero, have been shown to help maintain a steady lactate state, which helps active muscles stay active for longer and recover faster.

Muscular system: compounds in Overpower have been shown to suppress lactic acid buildup, boost ATP production, increase fat burning and act as superb electrolytes to deliver micronutrients into active muscle tissue.

Nervous system: compounds in Overpower have been shown to stimulate neurotransmission responsible for willpower, motivation, learning and fine motor skills.

Endocrine system: compounds in Overpower have been shown to help grow muscle and to suppress catabolic processes by modulating hormonal production cascades over multiple phases.

Respiratory system: compounds in Overpower have been shown to raise the ventilatory threshold and improve respiratory rate and VO2max.

Circulatory system: compounds in Overpower have been shown to modulate the resting heart rate and its recovery, as well as modulate nitric oxide production and therefore improve circulation and nutrient delivery.

On cortisol

Strain stimulates the release of hormone regulator cortisol, which has a catabolic effect on tissues. Too much cortisol for too long causes serious negative effects – a problem for endurance athletes whose long-term cortisol exposure is often high. All five adaptogens in Overpower have proven to suppress rising cortisol levels.


Mechanism of Action

Broad, multi-channel and networked modulation of physical stress reactions.

Areas of Application

Maintaining stamina and endurance across multiple physiological factors. Improving training response from endurance and resistance exercise. Improving recovery and quality of rest. Recovering from overtraining and hypogonadism. Reducing the risk of overtraining. Extended field operations.

Duration of Effect



Overpower has a flexible dosing range, ie. the suitable dose varies according to individual response and amount of external stress.

The recommended dose for active athletes is 3 capsules of Overpower Alpha and 3 capsules of Overpower Omega per day. This dose is suited for frequent exercise or when under strain.

Smaller doses of Alpha and Omega are recommended for more sedentary individuals, or when experiencing less strain and stress. We recommend trying out different dosing combinations to find the best individual response.

We recommend that the Alpha dose is taken in the morning or before noon, preferably at or near the same time every day. The recommended intake time for OP Omega is more flexible. It can be taken simultaneously with Alpha or e.g. an hour before exercise, or in the afternoon to boost OP Alpha and to provide energy for the rest of the day. We recommend that Omega is not taken late in the evening (unless the user is active at night-time), as it may affect sleep.

Things to note

Adaptogens are low in toxicity, have no tolerance build-up and possess no abuse potential. They do not alter the state of consciousness and their long-term use has not been reported to cause any psychological side effects.

The amounts of bioactive compounds in an Overpower dose correspond with the dosages that have induced verified performance-supporting results in both Rohtos Labs’ own product tests as well as scientific research by others. In general, the amounts of adaptogenic extracts in an Overpower dose fall into the low dose stimulatory range of concentrations.

If you are on medication, please consult your doctor for possible interactions.

Active ingredients

Cordyceps militaris belongs to the Cordyceps family of mushrooms, which consists of over 400 different mushrooms. Unlike most of its relatives, Cordyceps militaris grows on soil. The effects of Cordyceps on sports performance, hormonal function and oxygen intake has been studied over the last years, and Cordyceps supplementation has been found to increase endurance and oxygen intake in high intensity training, both acutely and over longer term. In addition, cordyceps has been shown to increase blood flow, possibly via nitric oxide modulation, and to improve oxygen utilization in tissues by increasing hemoglobin levels. Cordyceps Militaris in Overpower is a dual water - ethanol extract, whose beta glucan content is standardized at 20%, and cordycepin, a key constituent, at 0.3%.

Mucuna, or velvet bean, is a tropical legume native to Africa and Asia, and a natural source of L-DOPA, in a well-tolerated and highly bioavailable form. Supplementation with Mucuna has been shown to increase the levels of certain neurotransmitters, but also on specific occasions the levels of testosterone, luteinizing hormone, adrenaline and noradrenaline. In addition, Mucuna has been shown to help in muscle growth and to mitigate the effects of age-associated decline in energy levels, muscle mass, physical performance capability, blood circulation and cognitive capability. Neurotransmitters modulate multiple functions which differentiate active and sedentary body states, such as coordinating motor functions, feelings of reward and mood, they play a key role in supporting the mood-boosting effects of exercise and maintaining a high level of performance. Mucuna in Overpower is an extract from bio-organically grown beans, with its L-DOPA content standardized at 20%.

Ashwagandha, Withania somnifera, is a member of the nightshade family of plants. Ashwagandha is a major medicinal herb in Ayurvedic tradition of medicine with a wide body of scientific research to back up its efficacy. Its use has traditionally focused on stress and anxiety mitigation, but during the last years its performance-supporting capabilities have received some well-earned attention. With regards to Overpower and performance support, Ashwagandha pretty much does it all and does it well, as it has been shown to accelerate cell renewal, to decrease levels of stress hormone cortisol, to suppress inflammation, the levels of ‘bad’ LDL-cholesterol and the overall cholesterol levels. In addition, Ashwagandha has been shown to, when used in conjunction with exercise, to decrease the body’s fat percentage, to increase the formation of muscle mass in resistance training and to speed up the recovery of muscles after exercise. Ashwagandha modulates the resting heart rate, power output and aerobic capability of the body and suppresses the subjective feelings of exhaustion while active. In resistance-training males, Ashwagandha supplementation has been shown to increase the levels of testosterone more than resistance training without it. Ashwagandha in Overpower is Sensoril®, a branded extract made with a patented water extraction process from roots and leaves of Ashwagandha and whose glycoside, oligosaccharide and Withaferin A contents are standardized.

Shilajit is a natural substance formed for centuries by the gradual decomposition of certain plants by the action of microorganisms. It is a potent and very safe dietary supplement which has been utilized for thousands of years in the Himalayas, India, China and the Caucasus. The name Shilajit comes from sanskrit, where the word ‘shilajitu’ means rock tar. In Eastern Europe, the Caucasus and Arabic countries Shilajit is known in variations of the word ‘Mumiyo’. Shilajit contains tens of minerals in ionic form, including iron, molybdenum, zinc, manganese, calcium, strontium, copper and magnesium - organic acids such as humic and fulvic acid, as well as amino acids and hormone precursors. The ionic state of the elements enables them to bond readily with water, making it possible for the body to efficiently absorb it. Shilajit has been shown to increase the effect of resistance training by increasing the expression of genes which regulate muscle growth and by efficient delivery of micronutrients into deep muscle tissue. Thereby Shilajit has been shown to support performance levels in extreme conditions such as high altitude. In addition, Shilajit has been shown to modulate testosterone synthesis. Shilajit on Owerpower is organic and due to a specific purification process, very clean. Its levels of fulvic acid is standardized at >50%.

Coffee originates from a berry grown on trees. Its green seeds become coffee beans. Many compounds (and benefits) of the coffee beans are destroyed during the roasting process. Caffeine, despite its mundane status, is an excellent booster of mental and physical performance, which has been shown to increase vigilance, modulate the energy metabolism of the body, suppress exhaustion and to increase reaction speed and accuracy.In addition to caffeine, green coffee beans contain chlorogenic and ferulic acids, which have been shown to exert beneficial effects on blood pressure and blood sugar. Green Coffee bean in Overpower is an extract from organic green coffee beans with its caffeine content standardized at 95%.

Eleuthero, Eleutheroccus senticosus, also known as Siberian Ginseng, is a small shrub that grows in northeastern Asia, and which has been traditionally used by Siberian natives to cope with the harsh conditions. Eleuthero has been shown to improve oxygen intake, raise the anaerobic threshold, maintain healthy blood sugar levels and suppress lactic acid accumulation in active muscles. In addition, Eleuthero has been shown to lower the average resting heart rate and speed up heart rate’s return to normal rate post-exertion. Eleuthero is Overpower is an extract with eleutheroside B and E content standardized at 0.8%.

Rhodiola Rosea, also known as golden root, roseroot and Arctic root, is a perennial flowering plant which grows naturally in Arctic regions of Europe, Asia, and North America. It has been traditionally utilized in its native habitats to stave off tiredness and depression. In Scandinavia, first written remarks about medicinal use of Rhodiola are from the 18th century, but according to folklore, its utilization there started much earlier. Rhodiola has been shown to be a fairly universally effective in mitigating symptoms of mental and physical tiredness and therefore in improving the level of performance while stressed. In studies implemented with athletes, Rhodiola has been shown, among other effects, to lower the average resting heart rate, to improve concentration and lower the number of mistakes in execution, to increase the body’s use of fats as an energy source, and to support cellular energy production and blood sugar balance. Rhodiola also helps regulate neurotransmitter levels in the central nervous system. Rhodiola may be of interest to practitioners of contact sports, gamers and of other ventures requiring good reactions, as it has been shown to improve reaction speed. Rhodiola in Overpower is an extract with its salidroside content standardized at 3% and rosavins at 5%.

‘Ginseng’ typically refers to plants from genus Panax which grow natively across a wide area - Panax Ginseng in the Korean Peninsula, northern China and Russian Far East, American Ginseng (Panax quinquefolius) in the USA and Canada, South-China Ginseng (Panax Notoginseng) in southern China and Vietnamese Ginseng (Panax Vietnamensis) in Vietnam. Ginseng has been revered and utilized in Korea, China and Japan for over 2000 years. Commercial cultivation of Ginseng started already in early 18th century. All Ginsengs share some common bioactive compounds called ginsenosides, of which over 100 different types have been identified. Panax, or Korean Ginseng is considered to be the most efficacious of the Panax family of plants. With Ginseng, its root is typically utilized. There are two types of processed Ginseng root - white and red. White Ginseng is washed and peeled and then dried. Red Ginseng is steamed, and its red colour is the result of a Maillard reaction between carbohydrate and amino acid contents of Ginseng . In addition, Ginseng is fermented and its leaves are utilized in certain Ginseng extracts. Traditional uses of Ginseng have focused in providing energy, improving male sexuality and maintaining a Zen mindset. With regards to performance, Ginseng has been shown to boost sugar metabolism, improve oxygen delivery to muscle tissues, spare muscles from excess damage, and to increase the body’s use of fats as an energy source at the onset of activity. Several ginsenosides share structural similarities with human sex hormones. Ginseng in Overpower is white, air-dried Panax Ginseng root, with its ginsenoside content standardized at 30%.

Acerola, Malpighia emarginata, which is also known as Barbados cherry is an excellent natural source of vitamin C, but also of amino acids (including alanine, serine and GABA), anthocyanins, carotenoids and catechins (which it shares with tea), as well as polyphenols such as quercetin, luteolin and rutin. The combination with vitamin C and anthocyanins make Acerola an effective natural antioxidant to reduce oxidative stress and suppress inflammation. The vitamin C content of Acerola has been shown to increase the absorption of other key constituents in Overpower - L-DOPA, zinc and iron (from Shilajit), as well as beta glucans from Cordyceps. Vitamin C has also been shown to support efficient blood circulation. Acerola in Overpower is an extract from bio-organically grown Acerola, with its vitamin C content standardized at 25%.

Piperine is the alkaloid responsible for the pungency of black pepper (Piper Nigrum). Piperine can inhibit key liver enzymes that would otherwise break down other molecules faster. Due to this, it is ingested alongside supplements to increase their absorption rates. The purpose of piperine in Overpower is therefore to increase the absorption and bioavailability of other bioactive compounds and therefore make Overpower more effective. Piperine in Overpower is extracted from black pepper and has 95% purity.
