Half-life isn’t simply one other handy gaming metaphor, it’s additionally the time period that pertains to the length of a complement’s results in your physique. The longer an ingredient’s half-life, the longer it basically stays in your system delivering its results.

Nevertheless, these results progressively lower as your physique processes and digests the complement, leaving a diminished quantity of it circulating by means of your physique. While you take an efficient dose of a selected complement (or a formulated complement mix like a pre-workout), you’ll doubtless discover sure outcomes virtually instantly, earlier than they peak and finally taper off because the substances attain their half-lives. 

Usually talking, you need to take your pre-workout, a short while earlier than you start your coaching session. Relying on how thorough your warm-up is, contemplate taking your pre-workout 20 to 60 minutes earlier than arriving on the gymnasium. That ought to usually enable sufficient time for the vitamins to flow into by means of your system and ship their supercharge by the point you’re knee-deep into heavy squats.

Right here’s a extra particular have a look at the optimum timing and dosage for a few of the commonest pre-workout substances.


Caffeine is the Tetris of pre-workouts — even individuals who don’t play video video games are conscious of its affect, whereas they may not actually be clear on the main points. As a complement, caffeine has been proven to enhance anaerobic energy output and cardio endurance, lower emotions of fatigue, assist psychological focus, and enhance general power and efficiency. (1)(2)

An efficient dose of caffeine is roughly two to a few milligrams per kilogram of physique weight, or round 165 to 245 milligrams for a 180-pound (82-kilogram) individual. (1) Caffeine hits peak focus in most peoples’ programs inside 45 minutes, however might be so long as two hours relying on their general structure. The standard half-life of caffeine is three to seven hours, relying on elements equivalent to normal exercise degree, physique fats mass, and (apparently) cigarette or alcohol use. (3)(4)

With a doubtlessly lengthy half-life — which means caffeine is lively in your system for a comparatively very long time — lifters who prepare within the late afternoon or night can be higher off selecting a non-stimulant pre-workout to get a exercise increase with out affecting your sleep and post-workout restoration.


Whereas some sports activities dietary supplements are backed by little, if any, credible analysis, creatine monohydrate is without doubt one of the most totally researched dietary supplements in the marketplace. A long time of in-depth information assist the advantages of creatine, starting from elevated muscle development and energy to improved short-term restoration, even improved mind well being and cognitive operate. (5)(6)

Creatine dosing and timing is considerably distinctive, in that it’s not recognized for delivering fast results. As an alternative, widespread beneficial observe is to saturate your physique’s creatine shops for one to a number of weeks — both by utilizing a short-term “loading part” (taking 5 grams 4 instances per day) for one week or by taking a typical “upkeep dose” (5 grams per day) for as much as 30 days. (7)

Taking a single dose of creatine has not been proven to be useful. (8) A standalone dose of creatine may be very doubtless not dangerous. Nevertheless, if you happen to’re not constantly taking creatine, a lone serving will supply no important profit.

Beta-alanine is much like creatine, in that constant use (4 to 6 grams per day in divided doses) has proven to ship important outcomes. Nevertheless, not like creatine, taking beta-alanine sporadically in decrease doses (one and a half to 2 grams) does look like useful, so common consumption could also be helpful however not essential. (11)

With all that it affords by means of improved efficiency, beta-alanine does have a comparatively quick half-life. After roughly one hour, advantages considerably drop. Take this into consideration in case your pre-workout accommodates beta-alanine — ready too lengthy to hit the laborious units could depart you lacking out on its key advantages.


Arginine is usually categorized as a “non-essential amino acid,” which means you will get all of the arginine your physique wants for well being and fundamental operate by means of eating regimen alone with out particular supplementation. Nevertheless, to make use of arginine as a strategic sports activities complement, taking a devoted complement might be far more useful.

Doses of 1 and a half to a few grams have been proven to enhance athletic efficiency and reduce ranges of fatigue. (12) Arginine’s main technique of motion is by working as a nitric oxide (NO) booster. NO is related to elevated blood move and stronger muscle contractions, making it a well-liked selection for the burden room in addition to the bed room. (13)

Arginine is comparatively fast-acting and may attain peak effectiveness in as little as 20 minutes, with a half-life of as much as two hours. (13) The mixture of improved efficiency, comparatively quick-hitting affect, and comparatively lengthy length make it a tried and true pre-workout staple.


In some methods, citrulline is to arginine what the Energy Glove was to the Wii Match. Citrulline is a precursor to arginine, which means citrulline basically helps your physique course of arginine whereas delivering its numerous results. By itself, citrulline yields comparable, and doubtlessly better, results on NO manufacturing in comparison with arginine. (14)(15) This may result in an much more important increase to circulation, muscle contractions, and endurance.

Citrulline is proven to be efficient when three to 6 grams are taken per serving, and it yields a half-life of roughly one hour. Curiously, increased doses of citrulline could barely improve the efficient length of advantages, though they’re not essentially related to better efficiency advantages. (16)

Having the ability to prepare longer than standard — whether or not it’s further units for extra lifting quantity or spending just a few extra minutes in a cardio session — can result in better long-term progress.

Quicker Restoration Between Units

Recovering between exercises is comparatively straightforward. You’ve received hours and hours to eat, sleep, and loosen up. Recovering between units is a unique beast solely. 60 or 90 seconds by no means appear to go so quick while you’re outdoors of the gymnasium.

Many pre-workout substances enhance your physique’s capacity to get better in short-term intervals, together with between units. For instance, creatine and beta-alanine can each improve your physique’s capacity to supply ATP. ATP is principally “gas” in your muscle cells, so that you’re recharging them extra rapidly they usually’re able to work within the subsequent set sooner.

Whereas triple-digit caffeine ranges are widespread and may positively be efficient, extreme caffeine consumption could be a surefire option to sidetrack your exercise with an upset abdomen. Creatine is one other common ingredient which, relying in your particular person response, could doubtlessly result in GI misery in some individuals.

While you select to make use of a pre-workout, take steps to be sure you depart all of it within the gymnasium. Know your private tolerance, learn labels and verify dosages, and time your pre-workout correctly. Once more, if you happen to’re coaching later within the day and need to guarantee night time’s relaxation by avoiding stimulants, search for a pre-workout that’s particularly non-stimulating.

Pores and skin Tingles

One aspect impact uniquely widespread to pre-workouts which include beta-alanine is a “tingle” or itch. It’s usually brought on by an excessively excessive dose and is comparatively short-lived, typically lasting lower than an hour. It’s thought-about to be brought on by a kind of sensory overload, slightly than an precise allergic, histamine-based response. (17)

Curiously, not all individuals contemplate this a “aspect impact” and a few eagerly anticipate the feeling. It’s a person choice, however the secret is to do not forget that an efficient dose is usually lower than the tingle-producing dose. So if you happen to’re missing the itch, it doesn’t essentially imply your complement’s not working.
