IOH Nutrition · Peak Performance Pre-Workout
A pre-workout built to raise output, not heart rate.
Most pre-workouts solve one problem, feeling tired, by creating three more: a stimulant spike, a crash, and a night of thin sleep. Peak Performance was formulated the other direction. Fully disclosed doses, paraxanthine instead of a caffeine load, two nitric oxide pathways, real electrolytes, and nothing in the scoop that is only there to make it cheaper to produce.
And the point was never the buzz. The point is doing more work at the same effort. Two more reps before the burn shuts you down, a shorter rest period that still feels long enough, one more set at the end of a session you would normally have cut short. That is where this formula actually shines, and it is also where the adaptation lives.
What it is
A stimulant-light, fully-dosed pre-workout powder. Paraxanthine for drive, citrulline and beet root for blood flow, beta-alanine for work capacity, and a real electrolyte base.
What it does
Supports power output, time to fatigue, pump, and mental focus during training, without the jitter, the racing pulse, or the afternoon crash.
Who it is for
Adults who train hard and intend to keep training hard. Built first for men and women in their 40s, 50s, and 60s who care what happens to sleep and recovery afterward.
How to use it
Start with one scoop in 16 to 20 oz of cold water, 20 to 30 minutes before training, and stay there until you know how you respond. Two scoops is the full performance dose once you have assessed your sensitivity.
The difference
Two ways to build a pre-workout.
The industry standard
- A heavy caffeine load doing most of the work.
- Sucralose and acesulfame potassium for taste at the lowest possible cost.
- Artificial colors and flavor systems to make the tub look exciting.
- Maltodextrin, dextrose, and bulking agents padding out the scoop.
- One nitric oxide pathway, often underdosed.
- Proprietary blends that hide how little of the good material is actually in there.
- A finish that leaves you wired, then flat.
The IOH standard
- Paraxanthine for drive, so the nervous system is engaged rather than hammered.
- Allulose and organic stevia (Reb-M). Nothing artificial.
- No dyes, no artificial flavor package, no preservatives.
- No fillers and no bulking agents. If it is in the scoop, it has a job.
- Two nitric oxide pathways: citrulline malate and beet root nitrates.
- Every active printed on the panel with its milligram amount.
- A finish that leaves you capable, not depleted.
How it works
Four systems, working at once.
A pre-workout is not one ingredient with a marketing budget behind it. Performance is bioenergetics, blood flow, buffering, and conduction. This formula addresses all four.
01 — NEURAL DRIVE
Focus without the fallout
Paraxanthine is the metabolite caffeine becomes before your brain can use it. Starting there means faster onset, cleaner clearance, and less of the cortisol spike and late-night wakefulness a large caffeine dose brings with it.
02 — BLOOD FLOW
Two roads to nitric oxide
Citrulline malate at 6,000 mg, the amount used in the performance research, raises nitric oxide through the arginine pathway. Beet root nitrates contribute through a second, separate route. Better oxygen delivery, and pumps that hold rather than fade between sets.
03 — WORK CAPACITY
More work at the same effort
This is the one that matters most, and the one nobody markets. That burn in set four is rising acidity. Beta-alanine builds carnosine, your primary intramuscular buffer, so fatigue arrives later at the same perceived effort. Two scoops delivers 3,200 mg, the daily amount used across the research. More total volume for the same session, and volume is what drives adaptation.
04 — CONDUCTION
Electrolytes that are actually dosed
Sodium, magnesium, and potassium are what let a nerve fire and a muscle contract. Two scoops carries 200 mg sodium, 250 mg chloride, 100 mg magnesium, and 130 mg potassium from pink Himalayan salt and citrate minerals. Not a token pinch for the label.
The formula
What is actually in the scoop.
Every active is printed with its amount. Two scoops is the full performance dose, and that is the column matching how these ingredients were studied. One scoop is a genuine half-dose, listed here as well so you can decide for yourself.
| Ingredient | 1 scoop | 2 scoops · full dose |
|---|---|---|
| L-Citrulline Malate | 3,000 mg | 6,000 mg |
| Beta-AlanineCamoSyn® | 1,600 mg | 3,200 mg |
| Taurine-L-Malic Acid ComplexMalTor® | 2,500 mg | 5,000 mg |

40 servings per container at one scoop, 20 at two. Full Supplement Facts panel shown in the product images.
L-Citrulline Malate
6,000 mg at full doseConverts to arginine more efficiently than arginine itself does. Raises nitric oxide, widens vessels, and improves oxygen and nutrient delivery to working muscle. Six grams is the amount used in most of the performance research, which is exactly why it is the amount here.
Beta-Alanine (CamoSyn®)
3,200 mg at full doseBuilds intramuscular carnosine, the buffer that blunts the acid burn. 3,200 mg per day is the standard studied amount, and it works by daily accumulation rather than by any single dose, so consistency matters more than timing.
MalTor® Taurine-L-Malic Acid Complex
5,000 mg at full doseTaurine regulates calcium handling inside the muscle cell and steadies the nervous system under load. Malic acid is a Krebs cycle intermediate supporting ATP production and lactate handling. A branded, traceable form rather than a commodity blend.
enfinity® Paraxanthine
200 mg at full doseThe active metabolite your body converts caffeine into. Faster onset, cleaner clearance, and far less of the jitter-and-crash pattern. 200 mg is the amount used in the published paraxanthine work. It is still a stimulant, just a considerably cleaner one.
Cocoa Bean Extract
200 mg at full doseNatural methylxanthines and flavanols supporting vascular tone and cognitive engagement alongside the paraxanthine. It rounds out the neural side of the formula rather than adding another hard stimulant on top.
Organic Beet Root Powder
300 mg at full doseDietary nitrates that raise nitric oxide through a second pathway entirely separate from citrulline. A supporting contribution to blood flow rather than the main driver, which is the honest way to describe it at this amount.
Vitamin B12 (methylcobalamin)
1,000 mcg at full doseThe methylated, ready-to-use form rather than cyanocobalamin. Supports the energy metabolism and red blood cell production that oxygen delivery depends on. No conversion step required before your cells can use it.
Sodium and Chloride
200 / 250 mg at full doseThe primary conductors. Nerve impulses fire and muscles contract because sodium moves across a membrane, and sweat removes it faster than anything else on this list. Sourced from pink Himalayan salt.
Magnesium (citrate)
100 mg at full doseRequired for muscles to relax after contracting, which is precisely why low magnesium shows up as cramping and twitching. The citrate form is used here for absorption rather than the cheaper oxide.
Potassium (citrate)
130 mg at full doseWorks opposite sodium across the cell membrane to reset the nerve after each impulse. Depleted through sweat alongside sodium, and routinely left out of pre-workouts entirely because it costs money and adds nothing to the marketing.
Allulose, natural flavor, stevia leaf extract (Reb-M)
40 calories and 1 g carbohydrate per scoopThe sweetening and flavor system. Allulose and Reb-M stevia cost multiples more than sucralose, and they are here because I am not going to spend clinic hours telling people to avoid artificial sweeteners and then sell them one. No sucralose, no acesulfame potassium, no artificial sweeteners, no dyes. No maltodextrin, dextrose, or bulking agents anywhere in the scoop.
Taste and mixability
Sweetened the way I would sweeten it in clinic.
Most of the category tastes the way it does because sucralose is cheap and covers a lot of sins. This one is sweetened with allulose and Reb-M stevia, which cost considerably more and taste like sugar rather than like the aftertaste that follows sugar. Forty calories and a single gram of carbohydrate per scoop.
Nothing artificial in the glass
Zero sucralose, zero acesulfame potassium, zero artificial sweeteners, zero dyes, and no artificial flavor package. What colors the drink is what is actually in it.
No filler bulking the scoop
No maltodextrin, no dextrose, no volume padding. A scoop of this is actives and the flavor system, which is also why it does not have the thick, gritty body a filled pre-workout has.
One scoop first
Cold water, 16 to 20 oz, 20 to 30 minutes before training. Begin at one scoop and stay there for at least your first few sessions so you can assess your own sensitivity before moving up.
What to expect
Your first month, honestly.
Some of this you will notice on day one. Some of it takes weeks of consistent use, because that is how the chemistry works. We would rather tell you that up front than let you judge the beta-alanine on a single session.
Session 1
Onset in 20 to 30 minutes
Clarity that arrives smoothly rather than sharply. Warm-up sets feel easier to lock into. The test that actually matters is the one three hours later: no crash, and no argument with your sleep that night.
Weeks 1 to 2
Pumps and recovery between sets
The nitric oxide side works from the first dose and becomes more noticeable as training volume climbs. Rest periods start feeling shorter than they used to. Beta-alanine is loading quietly in the background.
Weeks 3 to 4
Carnosine catches up
Beta-alanine works by saturation, not by dose. Around here the fatigue point moves, and this is where the real benefit shows up: the same session starts producing more work at the same effort. The last two sets stop being the ones you talk yourself out of, and total volume climbs on its own.
Read the label
What to look for in any pre-workout.
Use this on us, and use it on whatever is currently in your cabinet. The point is not brand loyalty. It is knowing what you are drinking before you train.
| Checkpoint | IOH Peak Performance | Typical off-the-shelf pre-workout |
|---|---|---|
| Stimulant | enfinity® paraxanthine, 200 mg | High-dose caffeine anhydrous, often 300 to 400 mg |
| Sweetener | Allulose and organic stevia (Reb-M) | Sucralose, acesulfame potassium, or both |
| Color and flavor | No dyes, no artificial flavor package | Artificial dyes and proprietary flavor systems |
| Nitric oxide support | Two pathways — citrulline malate plus beet root nitrates | One pathway, frequently below the studied amount |
| Beta-alanine amount | 3,200 mg per day at two scoops — the studied daily amount | Often 800 to 1,600 mg, well under what the research used |
| Electrolytes | Sodium, magnesium, and potassium at meaningful amounts | Trace amounts, or absent entirely |
| Label transparency | Every active printed with its milligram amount | Blend totals only, hiding how little of each active is present |
| Fillers and bulking agents | None. No maltodextrin, no dextrose, no volume padding | Maltodextrin and bulking agents making the scoop look larger |
| After the session | Designed to leave recovery and sleep intact | Crash, appetite disruption, disturbed sleep |

How it fits your routine
What it pairs with, and why.
This formula covers the training window. It is deliberately not trying to be your daily foundation or your creatine, because those jobs run on different timelines and different physiology.
Pairs with
Pure Creatine
A sensible pairing with no overlap. Creatine works on the phosphocreatine system for short, heavy efforts, while this formula works on blood flow, buffering, and neural drive. They do not compete for the same mechanism. Creatine is also not timing-dependent, so take it whenever it is easiest to stay consistent, in or out of your pre-workout shaker.
Shop Pure Creatine
Pairs with
MitoHealth — Natural Energy Support Plus
The daily counterpart to this one. Peak Performance handles the session; MitoHealth handles the cofactors your cells need to make energy on every other day of the week. There is no stimulant in it, so the two never stack stimulants. Session support on top, cellular foundation underneath.
Shop MitoHealth
Pairs with
NAD Catalyst
The most mechanistically direct pairing on this list. Everything in this formula improves delivery, buffering, and drive — but the actual production of ATP runs on NAD cycling between its oxidized and reduced forms, thousands of times per second. NAD Catalyst supplies 500 mg of nicotinamide riboside plus 150 mg of ATP, which is a real clinical dose rather than a gesture. The malic acid in MalTor® feeds the Krebs cycle; NAD is the cofactor those enzymes require to use it. No stimulant in it, no ingredient duplication with this formula, and different timelines — this one acute, that one daily and cumulative.
Shop NAD CatalystStart with one scoop. I mean this.
Two scoops is the full training dose and it is the one matching the research: 6,000 mg citrulline, 3,200 mg beta-alanine, 200 mg paraxanthine. But I strongly encourage you to run one scoop first and assess your own sensitivity before you go anywhere near two.
Stimulant tolerance varies enormously between individuals, and paraxanthine is potent even though it is cleaner than caffeine. Beta-alanine paresthesia is also dose-related. Give yourself several sessions at one scoop, see how you respond during training and how you sleep that night, and step up only when you know. One scoop is not a consolation prize either — it is a genuine half-dose with a permanent place for easier training days and later sessions.

From the formulator
I could not find one I would hand a patient without a caveat.
I spent a long time looking. The good ones were stimulant bombs. The clean ones were underdosed. Almost all of them were sweetened with something I spend my clinic hours telling people to avoid. Eventually it became easier to build the thing than to keep apologizing for the alternatives.
So I built this one to the standard I use in practice: if an ingredient is in the scoop, it has a job, it has human data behind it, and it is present at an amount that reflects how it was studied. If it is only there to cut cost or move product off a shelf, it is not in here.
You should feel this within the first session. You should also feel fine at nine o'clock that night. Both of those are the point.

Questions, answered
Before your first scoop.
One scoop or two?
Start with one, and I strongly encourage that rather than merely suggest it. Assess your sensitivity across several sessions before you consider two. Stimulant tolerance varies widely between people, and beta-alanine paresthesia is dose-related, so there is nothing to gain by jumping straight to the full dose and something real to lose.
Two scoops is the full training dose. That is where citrulline reaches 6,000 mg, beta-alanine reaches 3,200 mg, and paraxanthine reaches 200 mg, the amounts these ingredients were actually studied at. Move up once you know how you respond, both during the session and that night. One scoop also remains a genuine half-dose with a permanent place: easier training days, later sessions, or an afternoon when you want the focus without the full stimulant load.
Will I get the beta-alanine tingles?
Some people do. It is called paresthesia, a harmless skin tingle across the face, neck, or hands that shows up 15 to 20 minutes in and fades within the hour. It is a known effect of beta-alanine, not a warning sign. Starting with one scoop for the first two sessions usually keeps it mild.
How is paraxanthine different from caffeine?
Your liver converts caffeine into three metabolites, and paraxanthine is the one accounting for most of the alertness effect. Starting with paraxanthine skips the conversion step, so onset is faster and clearance is more predictable. In practice that means less of the pounding pulse and cortisol spike, and less of the trailing edge that ruins sleep. It is still a stimulant. It is just a cleaner one.
Does it stack with NAD Catalyst?
It is arguably the best pairing in the line, and for a specific reason. This formula works on blood flow, buffering, neural drive, and conduction — everything around energy production. NAD is what sits inside it. Every contraction you make is funded by NAD cycling between its oxidized and reduced forms in glycolysis and the Krebs cycle. The malic acid in the MalTor® complex feeds that cycle directly, and NAD is the cofactor those enzymes require to process it.
Practically speaking, NAD Catalyst delivers 500 mg of nicotinamide riboside and 150 mg of ATP alongside niacinamide and Albion® di-magnesium malate. There is no stimulant in it, so nothing compounds with the paraxanthine here. The only overlap worth knowing about is magnesium, and combined they still land well within a sensible daily range. This one is acute and taken before training. That one is daily and cumulative. Different jobs, same system.
Can I take it in the afternoon or evening?
Paraxanthine clears faster than caffeine, which is why many people tolerate it later in the day. That said, everyone metabolizes stimulants differently. If you train in the evening, try it on a night you can afford a mediocre night's sleep before you make it a habit.
Can I stack it with creatine?
Yes, and it is a sensible pairing. Creatine works on the phosphocreatine system for short, heavy efforts; this formula works on blood flow, buffering, and neural drive. They do not compete. Creatine is also not timing-dependent, so take it whenever it is easiest to stay consistent.
Does it break a fast?
It is sweetened with allulose and stevia rather than sugar, and calories per scoop are minimal. Whether that counts as breaking a fast depends on how strictly you define one. For most people training fasted, it does not present a practical problem.
Why does it cost more per serving than the tub at the big-box store?
Because of what is in the scoop and what is left out. Licensed ingredient forms cost more than generic ones. Allulose and Reb-M cost more than sucralose. Full doses cost more than dustings, and there are no fillers taking up cheap volume. At $1.48 per scoop and $2.95 for the full two-scoop training dose, this sits at the premium end of the category. You can absolutely buy cheaper. What you cannot buy cheaper is this ingredient list.
I take blood pressure or heart medication. Is this appropriate for me?
Ask your prescribing physician first. This formula contains a stimulant and ingredients that affect vasodilation, both of which can interact with cardiovascular medications. That is a conversation to have with the person managing your prescriptions, not something to sort out from a product page.
What if it is not for me?
Reach out to us. Our refund policy is linked in the footer of every page, and we would rather hear that it did not work for you than have you keep a tub you do not use.

Train like the best years are still in front of you.
