The bottom line first
Most Indian pre-workouts deliver clinical caffeine doses and sub-clinical everything else. The blend is the marketing, not the formula.
A proprietary blend is a group of ingredients declared by total weight, with individual component doses hidden. Because FSSAI does not require per-ingredient disclosure for supplement blends (unlike the US FDA's recent stricter labelling), Indian manufacturers can list 6g of a "Performance Matrix" containing citrulline, beta-alanine, arginine, and taurine — without telling you that citrulline might be 500mg when the evidence-supported dose is 6,000–8,000mg.
The math is exposing: if the total blend is 6g and caffeine alone is 200mg, the remaining 5,800mg must cover every other active ingredient listed. Run those numbers against clinical doses and the picture becomes clear fast.
How proprietary blends work — and how to read them
Under current FSSAI labelling rules for dietary supplements, a manufacturer must declare total ingredient weight per serving but is not required to break down individual components within a named blend. This is the regulatory gap that makes proprietary blends possible.
The technique used by informed consumers to estimate component doses is called blend arithmetic: subtract the known or estimable weights of documented ingredients (caffeine, if declared separately; creatine, if separated) from the total blend weight, then distribute the remainder across the remaining listed ingredients. Listed order indicates descending quantity — so the first ingredient in a blend is present in the largest amount. The last ingredient may be present in milligram or even microgram quantities — sometimes called "label decoration."
An ingredient listed on a pre-workout label implies it has been dosed to produce an effect. This is often not the case. Adding 10mg of lion's mane mushroom extract (effective dose: 500–3,000mg) to a blend costs the manufacturer nearly nothing, adds a buzzword to the label, and produces no measurable effect. This practice is legal, common, and deliberately misleading.
Evidence-based effective doses for key ingredients
14 Indian pre-workouts: blend arithmetic applied
We applied blend arithmetic to 14 pre-workouts currently sold on Amazon India and Nutrabay. The methodology: take the total blend weight from the Supplement Facts panel, subtract separately declared ingredients (caffeine, creatine when listed outside blends), then apply the ordering principle to estimate component distributions. All products were purchased at standard retail price in March–April 2026.
| Product | Total blend (g) | Caffeine (declared) | Citrulline estimate | Beta-alanine estimate | Verdict |
|---|---|---|---|---|---|
| Transparent Labs BULK (imported) | 21.6g | 200mg | 8,000mg ✓ | 4,000mg ✓ | Full dose |
| MuscleBlaze Pre-Workout XXX | 5.5g | 200mg | ~800–1,200mg ✗ | ~600–900mg ✗ | Underdosed |
| Bigmuscles Xtreme Napalm | 7.0g | 250mg | ~1,000–1,500mg ✗ | ~500–800mg ✗ | Underdosed |
| Six Pack Nutrition Primal | 6.1g | 175mg | ~1,200mg ✗ | ~800mg ✗ | Underdosed |
| AS-IT-IS Nutrition Pre-Workout | 10.5g | 200mg (separate) | ~4,000mg (partial) ~ | ~2,400mg ~ | Partial dose |
| GNC AMP Pure Series | 14.2g | 200mg | ~3,000–4,000mg ~ | ~1,600mg ~ | Partial dose |
| Nutrabay Gold Pre-Workout | 5.0g | 150mg | ~700mg ✗ | ~500mg ✗ | Underdosed |
| Himalayan Organics Plant Pre-WO | 8.5g | 0mg (stim-free) | ~2,500mg ~ | ~1,800mg ~ | Partial dose |
| C4 Original (imported) | 6.2g | 150mg | ~1,000mg ✗ | 1,600mg ~ (declared) | Mixed |
| Optimum Nutrition Gold Pre | 13.5g | 175mg | ~3,000mg ~ | ~1,500mg ~ | Partial dose |
The pattern is consistent: caffeine is reliably dosed (200mg is the Indian-market standard), while ergogenic actives like citrulline and beta-alanine are systematically under-dosed in blends below 15g total weight. Caffeine produces a felt effect regardless of other ingredients — ensuring the product "works" for the user and drives repeat purchase, while the actual performance actives ride on the caffeine effect.
How to spot an underdosed pre-workout on a label
What to actually buy: the transparent-label alternatives
Products with transparent (open) labelling declare per-ingredient doses explicitly. In the Indian market, the best-value transparent pre-workouts are typically imported or from a handful of honest domestic brands. Alternatively, building a DIY stack from raw ingredients — citrulline, beta-alanine, caffeine — is the cheapest and most effective approach.
Buy raw ingredients separately from AS-IT-IS Nutrition or Nutrabay Essentials: L-Citrulline 6g (₹40–50/serving), Beta-alanine 3.2g (₹15–20/serving), Caffeine 200mg tablet (₹2–5/tablet — or just use chai). Mix citrulline and beta-alanine in water 30–45 minutes pre-workout and take caffeine separately. Total cost per serving: ₹55–75 vs ₹150–250 for a branded proprietary blend that underdelivers on both actives.
A word on stimulant loading and the Indian chai baseline
Most Indian pre-workout users have a significant caffeine baseline from chai and coffee (see our separate Caffeine & Chai guide). A pre-workout delivering 200–250mg of caffeine, on top of 200mg from daily chai, takes many users to 400–450mg — at the EFSA safety ceiling. Adding multiple pre-workouts per day, stacking energy drinks, or escalating doses chasing diminishing effects from caffeine tolerance compounds the risk of cardiovascular stress, anxiety, and disrupted sleep.4
