Jumbo Mass Gainer 1.5kg — 1,250 Calories & 50g Protein per Serving (FSSAI Lab-Tested India)
About Zenith Sports
Zenith Sports is an Indian sports nutrition brand on a single mission: make lab-tested, easy-to-digest protein supplements that Indian athletes can actually trust.
Founded in 2020 and headquartered in Bangalore, Zenith Sports was built to fix two problems that quietly hurt every Indian gym-goer — bloating from cheap whey, and uncertainty about authenticity. Our answer was an 8-enzyme digestive blend in every whey and mass gainer, paired with a two-step QR-code authenticity check on every pouch you buy.
What makes Zenith different
1. 8-enzyme digestive blend in every protein SKU
Every Zenith whey and mass gainer is fortified with Protease, Lactase, Lipase, Amylase, Alpha-galactosidase, Gluco-amylase, Invertase and Cellulase. The blend helps break down protein and lactose efficiently, so you get maximum absorption without the bloating most Indian users associate with whey.
2. USA-imported whey concentrate at 80% protein-by-weight
Our raw whey is imported from the USA — one of the world’s highest-quality whey supply chains — and processed to a clean 80% protein-by-weight concentrate. No fillers, no artificial sweeteners in our unflavoured range, no banned substances.
3. Lab-tested every batch, with proof
Zenith Sports products are manufactured by Medizen Labs Pvt Ltd at our partner facility in Bangalore. The facility holds an FSSAI license (No. 11215332000675) and is GMP-certified. Every batch is third-party lab tested for heavy metals and adulterants — and we publish the test reports on our product pages, not behind an email gate.
4. Two-step QR authenticity check on every pack
Counterfeiting is the worst-kept secret in Indian supplements. We fight it with a two-step verification on every pouch: scan the QR code on the front, then scratch and scan the hidden Scratch QR code inside. Both must match at our verification page for the product to be authentic.
Who we are
Zenith Sports is operated by Meltingpot Concepts Pvt Ltd, headquartered in Bangalore, Karnataka. We are an India-first brand. Every product is formulated for Indian bodies, Indian climate, and Indian price points — the same protein quality international athletes buy, without the international markup.

Jumbo Mass Gainer is a high-calorie shake built for hardgainers — athletes who train hard but struggle to eat enough food to support muscle growth. One serving delivers 1,250 calories, 50g of protein, complex and simple carbs for sustained energy and post-workout glycogen refill, plus a digestive enzyme blend that helps you process the calorie load without bloating. Not a magic muscle pill — the calories still need to be paired with structured strength training for lean gains. Manufactured at our FSSAI-approved (License 11215332000675), GMP-certified facility in Bangalore.
Hardgainer reality
Why most lean guys can't bulk on food alone.
If you've been told to eat more and it didn't work, this is why.
High maintenance calories.
Hardgainers often have high non-exercise activity thermogenesis (NEAT) — fidgeting, walking, restless metabolism. Your maintenance calories might be 200–400 higher than calculators predict. You need a real surplus, not a 200-calorie tweak.
Stomach volume limits.
To eat 4,000 calories in solid food, you need to eat constantly. Many hardgainers can't — small appetite, busy work, no time. A liquid shake delivers 1,250 calories in 5 minutes when solid food can't.
Post-workout absorption.
After heavy training, your muscles are primed to absorb carbs and protein. A fast-digesting shake post-workout hits this window better than waiting for solid food.
Digestive enzymes prevent bloat.
Most cheap gainers cause bloat because the body can't process 250g of carbs and 50g of protein efficiently. Our enzyme blend (amylase, protease, lactase) breaks them down faster — less gas, less heaviness.
Tested. Traceable.

Questions
The ones we get most.
Will I get fat?
Mass gainers add calories. Whether they build muscle or fat depends on your training. Lift hard with progressive overload while using it — you'll add muscle with some fat. Train casually and the calories go to fat. Mass gainers are a tool, not a magic spell.
How fast will I gain?
Realistic expectation: 0.5–1kg per week of weight gain on a real calorie surplus. Of that, ~0.2–0.4kg is muscle in a trained lifter. Faster gains = more fat.
Can I use it without training?
If you're trying to gain weight from being underweight, yes. But for muscle gain, you need progressive resistance training. Calories alone don't build muscle without the training stimulus.
Mix with milk or water?
Milk for extra calories (+150 from full-fat) and creamier taste. Water for fewer calories and faster absorption.
FSSAI approved?
Yes. License 11215332000675. GMP-certified facility by Medizen Labs in Bangalore.
Halal-friendly?
Yes — manufactured in a facility that adheres to halal and vegetarian standards. Whey is dairy-based.
