Spend any time in the supplement aisle and a pattern emerges: nearly every pre-workout on the shelf is the same handful of ingredients wearing a different label. A 2019 analysis of the top 100 products (Jagim et al., Nutrients) put hard numbers on it — an average of 18 ingredients per label, 44.3% of them folded into proprietary blends that conceal the doses, and beta-alanine averaging 2.0 g against the 4–6 g the ISSN calls efficacious. The shelf price for that opacity runs $1.50–3.00 a scoop.
The alternative is a build-it-yourself approach: buy the workhorse ingredients in bulk, weigh them once, and mix per serving. Below are the four builds worth knowing — a starter stack, a full clinical-dose version, a stimulant-free pump blend, and a loaded nootropic — followed by the safety note that matters most.
Why the doses, not just the ingredients, matter
Pre-workout marketing sells ingredient lists, but the dose is where products live or die. The category's signature move is the proprietary blend — a lumped gram total that can list beta-alanine on the label while delivering a fraction of the studied amount. In the 2019 analysis, the average product's beta-alanine came in at 2.0 g, half or less of the 4–6 g range used in the research those labels cite.
Weighing your own inverts the equation: the dose on the scale is the dose in the glass, every time.
The four builds
The $0.60 base
START HERE| Citrulline malate 2:1 | 6 g | $0.30 |
| Beta-alanine | 3.2 g | $0.10 |
| Caffeine anhydrous | 200 mg | $0.07 |
| Creatine monohydrate | 5 g | $0.20 |
≈ $0.67 per serving
Mix in 300–400 ml of water 30 minutes out. This is the community's canonical stack — everything in it is evidence-dosed.
Full clinical
STIM| Citrulline malate 2:1 | 8 g | $0.40 |
| Beta-alanine | 3.2 g | $0.10 |
| Caffeine anhydrous | 200–400 mg | $0.10 |
| Creatine monohydrate | 5 g | $0.20 |
| L-Tyrosine | 2 g | $0.20 |
≈ $1.00–1.20 per serving
What the $45 'fully loaded' tubs claim on the front and dilute on the back — at actual studied doses.
Stim-free pump
NON-STIM| L-Citrulline | 6 g | $0.30 |
| Creatine monohydrate | 5 g | $0.20 |
| Glycerol powder | 2 g | $0.05 |
| Taurine | 2 g | $0.10 |
≈ $0.65 per serving
All pump, no ceiling-stare. For evening sessions or caffeine resets. Optional add: agmatine 1–1.5 g.
Loaded nootropic
FOCUS| The $0.60 base | 1 serving | $0.67 |
| Alpha-GPC | 300–600 mg | $0.50 |
| L-Tyrosine | 1–2 g | $0.20 |
| Huperzine A | 200 mcg | $0.15 |
| Rhodiola rosea | 300 mg | $0.40 |
≈ $1.90–2.60 per serving
Still under the $3 'nootropic' tubs — and every dose is on the label because you wrote the label.
The flavor question
One honest caveat: the raw mix tastes like what it is. Citrulline malate is sour, beta-alanine bitter, and water alone won't hide either. The standard fix costs about $0.16 a drink — a squeeze of MiO or Crystal Light. The natural route is stevia plus citric acid, or simply a squeeze of lemon; the tartness masks the citrulline nicely.
Worth repeating, because it's the most common beginner mistake: buy every ingredient unflavored. Two flavored products layered together taste worse than unflavored alone.
Mix per serving, or batch a jar
The gram-scale ingredients — citrulline, creatine, beta-alanine — mix evenly enough to pre-batch in a jar and scoop. Anything measured in milligrams is a different story: 200 mg of caffeine in a 500 g tub is a 1:2,500 ratio that stirring cannot distribute evenly. Weigh the micro doses per serving, or use the geometric-dilution technique covered in the setup guide.
