Alpha Lion SuperHuman Pre — Tri-Source Caffeine with Delayed Release

Alpha Lion SuperHuman Pre

A stimulant-forward pre-workout built around the SXT Energy System — a tri-source caffeine blend that is genuinely different from how most brands approach the problem — alongside clinical beta-alanine and betaine.

Extended release and delayed release are not the same thing

This is the most interesting thing about the product, and the distinction is one nobody explains.

The SXT Energy System combines three caffeine forms:

• Caffeine anhydrous — immediate. Peaks in roughly 30 to 45 minutes
• zumXR extended-release caffeine — starts releasing straight away, but slowly and continuously, spreading its contribution across the session
• zumXR delayed-release caffeine — this is the unusual one. It does not release gradually from the start. It holds back, then releases later

That difference matters. An extended-release ingredient produces a low, flat contribution throughout. A delayed-release ingredient produces a second pulse — arriving as the anhydrous portion is declining.

So the intended curve is: an immediate hit, a steady underlying level, and a second wave later on. That is a more sophisticated approach than simply mixing fast and slow forms, and it is designed specifically to address the crash rather than just soften it.

How this compares to the other approaches on our shelf:

Caffeine citrate	Fastest absorption	110 Percent High Voltage
Anhydrous	Standard	Nearly everything
Di-caffeine malate	Salt form, gradual	CBUM Thavage
Microencapsulated	Physically coated, slow	Fresh Pre
zumXR delayed-release	Second pulse later	SuperHuman Pre

One practical consequence: a delayed-release caffeine extends the effect further into your evening than the headline number suggests. If you train late, that is a genuine consideration — the tail is longer than an equivalent dose of plain caffeine.

⚠ If your tub lists L-Norvaline

Some versions of SuperHuman Pre include L-norvaline at around 60mg.

It is there as an arginase inhibitor — arginase breaks arginine down, so inhibiting it extends nitric oxide elevation. Sound mechanism, and the same job agmatine does in NovaPump Neuro.

The concern is safety. Published laboratory research on cultured neuronal cells found signs of toxicity at concentrations that were not especially high. That work was in vitro — cell culture, not humans — so it does not establish harm from supplement use, and the human relevance is unclear.

But many formulators removed it in response, including Project AD, who took it out of NITR-OX. We think that was the right call. If you would rather avoid it, check your panel.

The performance side

• Beta-Alanine, 3,200–3,500mg — at or slightly above the researched dose. Expect tingling; that is paraesthesia, harmless, and not a sign the product is working. Carnosine builds over two to four weeks
• Betaine Anhydrous, 2,000–2,500mg — around the clinical dose associated with strength and power output
• L-Tyrosine, 1,500mg — precursor to dopamine and noradrenaline, researched for cognitive performance under stress
• L-Theanine — reduces the jittery edge of caffeine while preserving alertness. Some versions list 350mg, which against ~325mg caffeine is better than a 1:1 ratio and considerably better than most high-stim products manage
• Taurine, 1,000mg — cell volumisation
• Nitrosigine (in some versions) — inositol-stabilised arginine silicate, supplying arginine directly rather than via citrulline
• AstraGin and BioPerine — absorption enhancers

⚠ Honest note on the citrulline

Depending on version, SuperHuman Pre carries either 4 to 5g of pure L-citrulline or 7g of citrulline malate.

Both sit below the 6 to 8g range the research supports for pump and endurance — 7g of citrulline malate delivers only around 4.7g of actual citrulline, since roughly a third of the weight is malic acid.

Alpha Lion partly compensate with S7 and, in some versions, Nitrosigine — which work on nitric oxide through different mechanisms rather than adding more substrate. That is a reasonable design choice.

But if pumps are your priority, this is not the strongest option on our shelf. MVPre 365 and DEFY both carry 10g of pure citrulline. Buy SuperHuman Pre for the energy profile, which is where it is genuinely distinctive.

S7 — the honest read

S7 at 50 to 100mg is a blend of seven plant extracts that appears to upregulate endothelial nitric oxide synthase, so your body produces more of its own nitric oxide.

The frequently quoted "increases nitric oxide by 230%" figure comes from the ingredient manufacturer's own research on a small sample. The mechanism is plausible and the dose matches what was studied, but treat a headline percentage from supplier-funded work with caution.

Consistent with our Pump Script and Fresh Pre pages.

How to take it

• Start with half a scoop in 6 to 8oz of water to assess tolerance.
• One scoop, 20 to 30 minutes before training. Do not exceed one scoop per day.
• Avoid within four to six hours of bedtime — and be aware the delayed-release portion extends that window further than plain caffeine would.
• No other caffeine or stimulant products that day.
• Take it consistently if the beta-alanine matters.
• Take creatine separately.

Who this is for

• Anyone whose main complaint about pre-workouts is the crash — the delayed-release caffeine targets exactly that
• People training long sessions who want energy that lasts rather than spikes
• Anyone who wants clinical beta-alanine and betaine alongside a strong stimulant profile
• People who want a fully disclosed label
• Anyone who finds high-caffeine products jittery — the theanine content in some versions is unusually generous

Who this is not for

If pumps are your priority, the citrulline is below the researched range. MVPre 365 or NITR-OX deliver far more.

If you train in the evening, the delayed-release caffeine extends the tail well beyond what a comparable dose of anhydrous would.

If your tub lists L-norvaline and you would rather avoid it, see the note above.

Beginners at a full scoop, and anyone caffeine sensitive.

Anyone with a cardiovascular condition, high blood pressure or an anxiety disorder.

Not for anyone under 18, pregnant or nursing. Speak to your doctor before use if you take any prescription medication.

Stack it with: creatine, or a stim-free pump product if you want more from the pump side.

Frequently asked questions

What is the SXT Energy System?
A tri-source caffeine blend combining anhydrous with zumXR extended-release and delayed-release caffeine.

What is the difference between extended and delayed release?
Extended-release begins immediately but releases slowly and continuously. Delayed-release holds back and then releases later, producing a second pulse as the initial dose declines.

How much caffeine is in it?
Listings vary between 300mg and 375mg depending on version. Check your tub.

Is the citrulline dose high?
No. Depending on version it is 4 to 5g of pure citrulline or 7g of citrulline malate (about 4.7g actual) — both below the 6 to 8g researched range. Buy this for the energy profile rather than the pump.

Does it contain L-norvaline?
Some versions do. Laboratory research on cultured neuronal cells raised toxicity concerns, and many formulators removed it. Check your panel.

Why does it make me tingle?
Beta-alanine at 3.2 to 3.5g. Harmless paraesthesia, and not an indicator the product is working.

Will it keep me awake?
Potentially longer than you expect. The delayed-release caffeine extends the tail beyond a comparable dose of plain caffeine.

Does it contain creatine?
No. Take creatine separately and daily.
