Mass Gainer 3kg Double Rich Chocolate — 50g Protein, Enzyme Blend, 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.

Mass Gainer 3kg DRC is the bulk-size version of our mass gainer, built for hardgainers committed to a 12-week bulk cycle. One ~330g serving delivers approximately 1,200 calories, 50g of protein from whey concentrate blend, complex and simple carbs for post-workout glycogen refill, and a digestive enzyme blend to make sure those calories are absorbed cleanly without the bloat that cheap gainers cause. Double Rich Chocolate flavor mixes well in cold milk. Manufactured at our FSSAI-approved (License 11215332000675), GMP-certified facility in Bangalore. Lab-tested for protein potency every batch.
When to size up to 3kg
1.5kg vs 3kg — which to pick.
| Jumbo 1.5kg | Mass Gainer 3kg | |
|---|---|---|
| Servings | ~4–5 | ~9 |
| Best for | Trying it out | Committed 8–12 week bulk |
| Cost per serving | Higher | Lower |
| Calorie load | 1,250 kcal | ~1,200 kcal |
| Protein | 50g | 50g |
| Enzyme blend | Included | Included |
Start with 1.5kg if you're testing tolerance and flavor. Move to 3kg once you know you'll use it daily for 6–8 weeks straight.
The training context
Why most bulks fail.
Too small a surplus.
If you add 200 calories and expect to gain, you'll be disappointed. Real bulks need 400–700 calories above maintenance, sustained for 8+ weeks.
Inconsistent intake.
Crushing it Monday–Friday then losing track on weekends erases the week. Mass gainers solve this — 1 shake covers the gap on busy or low-appetite days.
No progressive overload.
Without adding weight to the bar over time, extra calories build fat, not muscle. Eat the gainer; train the program; track both.
Quitting before the curve kicks in.
Real bulks show meaningful change at week 6–8, not week 2. 3kg gives you 9 servings — enough to bridge to the part of the curve where results start showing.
Tested. Traceable.

Questions
The ones we get most.
How long will 3kg last?
About 9 servings. At 1 serving/day, that's about 9 days. At 5 servings/week (rest days off), it's about 1.5 weeks. Most users buy 3kg for the cost-per-serving advantage on long bulks.
Can I split a serving?
Yes — half a serving (~165g, ~600 kcal) twice a day is easier on appetite for some users. Same total calories, less stomach load per shake.
Will I get fat?
Depends on training. With progressive overload strength training, most of the gain is muscle with some fat. Without training, most is fat. Mass gainers are a tool that follows your program.
Mix with milk or water?
Milk for extra calories (+150 from full-fat) and creamier flavor. Water for fewer calories and faster absorption.
FSSAI approved?
Yes. License 11215332000675. GMP-certified facility by Medizen Labs in Bangalore.
Lactose-friendly?
Our enzyme blend includes lactase, which helps reduce GI discomfort for mildly lactose-sensitive users. Severely lactose-intolerant users should avoid all whey-based gainers.
