Creatine is an [[enodgenous]] molecule that stores high-energy phosphate groups in the form of phosphocreatine (creatine phosphate). During periods of stress or strenuous exercise, phosphocreatine releases energy to aid cellular function. This is what causes strength increases after creatine supplementation, but this action can also aid the brain, bones, muscles, and liver.

Summary sheet: Creatine |
Creatine (and it's derivatives hydrochloride, malate, nitrate, etc) is a nitrogenous organic acid that occurs naturally in vertebrates and helps to supply energy to all cells in the body, primarily muscle. This is achieved by increasing the formation and accessibility of energy in the form of adenosine triphosphate (ATP). Creatine was identified in 1832 when Michel Eugène Chevreul isolated it from the basified water-extract of skeletal muscle. He later named the crystallized precipitate after the Greek word for meat, κρέας (kreas). Early analysis showed that human blood is approximately 1% creatine.
Creatine is a molecule that stores high-energy phosphate groups in the form of phosphocreatine (creatine phosphate). During periods of stress, phosphocreatine releases energy to aid cellular function. This is what causes strength increases after creatine supplementation, but this action can also aid the brain, bones, muscles, and liver. Most of the benefits of creatine are provided through this mechanism.
Creatine can be found naturally in some foods such as meat, eggs, and fish. Creatine supplementation confers a variety of benefits, notably neuroprotective and cardioprotective. It is often used by athletes and bodybuilders to increase both power output and lean mass.
Chemistry

Synthetic creatine is usually made from sarcosine (or its salts) and cyanamide which are combined in a reactor with catalyst compounds. The reactor is heated and pressurized, causing creatine crystals to form. The crystalline creatine is then purified by centrifuge and vacuum dried. The dried creatine compound is milled into a fine powder for improved bioavailability. Milling techniques differ, resulting in final products of varying solubility and bioavailability. For instance, creatine compounds milled to 200 mesh are referred to as micronized.[1]
Pharmacology
Creatine is an enodgenous molecule that stores high-energy phosphate groups in the form of phosphocreatine (creatine phosphate). During periods of stress or strenuous exercise, phosphocreatine releases energy to aid cellular function. This is what causes strength increases after creatine supplementation, but this action can also aid the brain, bones, muscles, and liver. Most of the benefits of creatine are provided through this mechanism.
Subjective effects
The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. The listed effects will rarely (if ever) occur all at once, but heavier dosages will increase the chances and are more likely to induce a full range of effects.
In comparison to the effects of other nootropics such as noopept, this compound can be described as conferring both physical stimulation and cognitive stimulation.
Sensory effects
- Perception of increased weight - Creatine may have a large effect on increasing overall weight due to water retention. Due to this, creatine, rather than altering perception, manifests itself in a physical bodily change. Degree of increase is dosage-dependent.
- Appetite enhancement
- Bodily control enhancement
- Stamina enhancement
- Tactile enhancement
Physical effects
- Stimulation - The stimulation which Creatine presents can be considered as subtle, yet persistent and energetic comparable to that of caffeine, yet even less forced in nature.
- Headaches
- Muscle spasms
- Stomach cramps
- Dehydration
- Diarrhea
Cognitive effect
- Wakefulness
- Rejuvenation
- Anxiety suppression
- Thought connectivity
- Thought organization
- Focus enhancement
- Analysis enhancement
- Motivation enhancement
- Memory enhancement
- Irritability
Toxicity and harm potential
There are no clinically significant side-effects of creatine supplementation acutely. Numerous trials have been conducted in humans with varying dosages, and the side-effects have been limited to gastrointestinal distress (from too much creatine consumption at once) and cramping (from insufficient hydration).
Studies that use a dosage range typical of creatine supplementation (in the range of 5g a day following an acute loading period) note increases to total body water of 6.2% (3.74lbs) over 9 weeks, 1.1kg over 42 days,[2] . This effect may be responsible for creatine's capability to increase perceived body weight.
Regardless, it is strongly recommended that one be familiar with harm reduction practices when using Creatine.
Tolerance and addiction potential
The chronic use of Creatine can be considered as not addictive with a low potential for abuse. It does not seem to be capable of causing psychological or physiological dependence among users.
