What this protocol is
This is a supplement protocol, not a training programme. The supplements fill the gaps. The bar builds the muscle.
5kg of lean mass over 16 weeks is aggressive for an intermediate lifter but achievable for someone in their first 1–2 years of serious resistance training. Expect the first 1–2kg of scale weight to arrive in week 1 from creatine-driven glycogen loading and intramuscular water — that's not fat, and it's not magic. The remaining 3–4kg of contractile tissue requires a caloric surplus, progressive overload, and 7–8 hours of sleep.
This protocol supplements those three non-negotiables. It does not replace them. Five compounds with RCT evidence specifically relevant to the lean mass goal: whey protein, creatine monohydrate, micellar casein, omega-3 EPA+DHA, and the Foundation Stack carry-overs (Vitamin D3 + K2, multivitamin). If you don't have the Foundation Stack in place first, start there before building this stack on top.
Before you start — the hierarchy that matters
The dominant variable for lean mass gain is caloric surplus — not creatine, not casein, not anything in a supplement bottle. A 70kg male lifter with a desk job and 4 training sessions per week has a TDEE of approximately 2,400–2,600 kcal. A productive lean bulk adds 200–300 kcal above maintenance: 2,600–2,900 kcal/day. Most Indian gym-goers eating chicken-rice-dal-chapati are at maintenance or below, not in a surplus. Supplements cannot create a caloric surplus from nothing.
Below that is the protein target. At 2–2.2g/kg, a 70kg lifter needs 140–154g protein/day. The realistic Indian gym diet — 150g chicken breast (30g protein) + 2 chapati (10g) + 1 cup dal (14g) + rice + vegetables — delivers approximately 80–90g of protein. The supplement gap is 60–70g per day. This protocol fills that gap precisely with whey + casein at the doses studied, not inflated scoops to compensate for poor dietary protein.
A mass gainer is maltodextrin (fast-digesting glucose polymer) with some protein and a price premium. The "1,000 kcal per serving" claim is carbohydrate calories — cheaper from rice, roti, or potatoes at a fraction of the cost. If you need a caloric surplus, eat more food. If you need protein, buy whey. A 3kg mass gainer at ₹2,500 provides ~105g protein across 30 servings — equivalent to 1kg of plain whey at ₹1,200. The math is not subtle.

The 70kg lifter's daily protein map
Before choosing supplements, map where your protein is actually coming from. Most lifters overestimate dietary protein by 30–40%. The breakdown below reflects realistic Indian meals — not bodybuilding meal plans from US fitness sites.
1.Whey protein concentrate
The post-workout leucine spike from a single whey serving triggers mTORC1-mediated muscle protein synthesis at its highest daily peak. The Lean Mass Builder uses one targeted scoop post-workout — not two scoops twice a day — because the casein handles the overnight anabolic window. Budget is better spent on quality casein and omega-3 than on doubling whey.
Why post-workout timing matters here (when it usually doesn't)
In general protein research, total daily intake dominates over timing. But in a lean mass protocol where total intake is already engineered — whey post-workout, casein pre-sleep, food across the day — timing does the job each compound was selected for. Post-workout, skeletal muscle is in a state of elevated mRNA translation for mTOR targets for approximately 24–48 hours, with the highest sensitivity in the first 2–3 hours. A whey shake providing 2.5–2.7g of leucine within 60 minutes of training delivers the mTORC1-activating signal at the point of maximum ribosomal sensitivity.1
Morton et al. (2018) meta-analysis of 49 RCTs (n=1,863): protein supplementation produced a 0.75kg lean mass advantage over control (95% CI: 0.37–1.13kg) and +2.49kg 1-rep max strength.2 Effect was proportionally larger in individuals below adequate protein intake — the position most Indian beginners occupy before supplementation.
Vegetarian note
Whey is lacto-vegetarian. Vegans need a pea+rice protein blend at equivalent dose — see the Pure-Veg Stack for that configuration. The leucine content of pea protein (8.4g leucine per 100g protein) is lower than whey's 11g — supplement with 2.5g standalone leucine if using a plant-based post-workout shake to ensure the mTORC1 threshold is crossed. See the leucine ingredient entry →

| Brand & product | ₹ / kg | Protein / 100g | COA | Our take |
|---|---|---|---|---|
| Nakpro Perform Whey | ₹1,399 | 80 g | NABL published | Best pick for this protocol. Clean label, honest protein count, consistent purity track record. Verified brand. |
| AS-IT-IS Nutrition Whey | ₹1,199 | 79 g | Partial | Best budget option — protein per rupee is unmatched at this tier. Minor COA gap is the only concern. |
| MuscleBlaze Biozyme Performance | ₹1,799 | 75 g | Partial | EAF enzyme blend is a marketing claim, not a mechanism. Paying ₹400/kg for a story. Score: 6.4 / 10. |
| ON Gold Standard Whey | ₹3,299 | 76 g | Published (US) | Strong label honesty. Import premium is hard to justify vs Nakpro at half the price per gram. |
Prices from Amazon.in, May 2026. In this protocol, 1 scoop (25g) consumed on training days only = ~22 servings/month = ~0.55kg. Budget accordingly — one 1kg pack lasts ~6–7 weeks.
2.Creatine monohydrate
Creatine monohydrate is already covered in depth in the Foundation Stack. In the Lean Mass Builder context, the key distinction is its interaction with training volume — creatine's lean mass benefit is proportional to how hard you train, not a fixed effect.
Volume × creatine synergy
Rawson and Volek's 2003 meta-analysis of 22 studies found that creatine users gained on average +1.37kg more lean mass than placebo groups over 4–12 weeks of resistance training at equal volume.3 Critically, this benefit was larger in studies with higher training volume — creatine is not a resting compound, it amplifies the signal from progressive overload. A lifter doing 3 sets per muscle group twice a week gets less benefit than one doing 4–5 sets 4x/week. This protocol assumes 4 training sessions per week with 15–20 sets per muscle group across the week.
Creatine also loads muscle glycogen: Greenhaff et al. demonstrated a 14–16% increase in glycogen synthesis when creatine was co-ingested with carbohydrate post-exercise.4 In the lean bulk context where training fuel matters, this is genuinely useful — the 1–2kg scale weight increase in week 1 reflects glycogen + water loading, not fat gain.
For full mechanism, brand table, and loading protocol detail, see the Foundation Stack creatine section.

5g/day × 30 days = 150g/month = half a 300g pack. Buy one 300g pack every 60 days — simplest reorder frequency for this protocol.
3.Micellar casein (pre-sleep)
This is the compound that distinguishes the Lean Mass Builder from the Foundation Stack. Micellar casein is the only supplement in this protocol with evidence specifically tied to the pre-sleep anabolic window. It is also the most commonly confounded by inferior products on the Indian market.
Mechanism — the 5-hour amino acid drip
Casein in native micellar form contains calcium phosphate bridges holding hydrophobic proteins in a spherical micelle structure. In the acidic environment of the stomach (pH ~2), this structure collapses into a gel — slowing gastric emptying dramatically. Van Loon et al. demonstrated that micellar casein produces a sustained, low-amplitude plasma amino acid elevation lasting 5–7 hours versus whey's rapid peak-and-trough over 2 hours.5
During the overnight fast — typically 7–8 hours — skeletal muscle shifts from a net anabolic state to net catabolic breakdown of contractile proteins. The pre-sleep casein feeding pattern interrupts this by sustaining plasma leucine and essential amino acid availability above the threshold required to maintain a positive muscle protein balance throughout the night.
The Snijders evidence — the landmark study
Snijders et al. (2015, Journal of Nutrition) — a double-blind, randomised, placebo-controlled trial in 44 trained young men over 12 weeks of resistance training: the 40g casein pre-sleep group gained significantly more lean mass (+1.3kg vs placebo) and greater quadriceps cross-sectional area on MRI, with higher 1-rep max on leg press and leg extension.6 This was not an acute study — it showed a real structural outcome over a training block. Res et al. (2012) preceded this with an acute mechanistic study showing 40g casein at 30 minutes pre-sleep increased overnight whole-body protein synthesis by 22%.7
Most Indian products labelled simply as "casein protein" contain calcium caseinate — a heat-processed form where the native micelle structure is destroyed. Calcium caseinate dissolves readily in water and digests at an intermediate rate, not slowly. It loses the 5-7 hour sustained release that makes micellar casein effective pre-sleep. Always look for "micellar casein" or "native micellar casein" explicitly on the ingredient list. If the label just says "casein protein" without specifying micellar, assume it is calcium caseinate.
Vegetarian alternative
There is no plant-based slow-digesting equivalent to micellar casein. Soy protein isolate has an intermediate digestion rate and complete amino acid profile — a large pre-sleep serving of 40g soy isolate is the closest substitute. Rice + pea blend digests similarly to soy at this dose. None of these has been studied in direct pre-sleep RCTs. The effect is likely present but magnitude is lower than casein.
India brand comparison — Micellar casein
| Brand & product | ₹ / 500g | Form | COA | Our take |
|---|---|---|---|---|
| AS-IT-IS Micellar Casein | ₹699 | Micellar confirmed | Partial | Best value in India. Micellar form explicitly labelled. Unflavoured mixes clean in warm water or milk. Pre-sleep use makes flavour irrelevant anyway. |
| Nutrabay Pure Micellar Casein | ₹649 | Micellar labelled | Not published | Marginally cheaper than AS-IT-IS. No COA — buy from AS-IT-IS if you can spend the extra ₹50 for better traceability. |
| MuscleBlaze Slow Protein | ₹1,299/kg | Casein + whey blend | Partial | Not pure micellar — faster digestion than pure casein due to whey fraction. Usable but not the same overnight amino acid profile as pure micellar. |
| ON Gold Standard 100% Casein | ₹3,499/908g | Pure micellar | Published (US) | Imported clinical benchmark. This is the form used in Snijders et al. The import premium is steep — AS-IT-IS delivers the same micelle structure at ₹700 per 500g. |
40g/night × 22 training nights/month = 880g/month ≈ 1.75× 500g packs of AS-IT-IS ≈ ₹1,225/month. Factor this into the cost tier calculation below. FSSAI: casein protein is permissible under FSSAI Health Supplements Regulations 2022.
4.Omega-3 EPA + DHA
Omega-3 is the most overlooked compound in Indian muscle-building protocols. It is not a stimulant, not a dramatic mass-gainer, and not marketed with before/after photos. What it does is shift the inflammatory and hormonal environment in skeletal muscle in a direction that measurably favours protein synthesis and limits protein breakdown — a dual mechanism no other supplement in this protocol addresses.
Muscle protein synthesis mechanism
Smith et al. (2011, American Journal of Clinical Nutrition) — a double-blind RCT in 16 healthy adults: 4g omega-3/day for 8 weeks significantly increased mTOR phosphorylation (+50%), p70S6K1 phosphorylation (+2.3-fold), and muscle protein fractional synthesis rate (+30%) in response to hyperaminoacidaemia + hyperinsulinaemia.8 The mechanism: DHA and EPA incorporate into the phospholipid bilayer of the sarcolemma, altering membrane fluidity and the clustering efficiency of insulin and IGF-1 receptor tyrosine kinases. A more fluid sarcolemmal membrane produces faster downstream mTOR signalling from the same amino acid and insulin stimulus.
Anti-catabolic mechanism
McGlory et al. (2019, Journal of Physiology) — a randomised crossover trial: 5g omega-3/day for 4 weeks significantly attenuated muscle protein breakdown during 2 weeks of unilateral leg immobilisation compared to placebo.9 The mechanism is distinct from the anabolic pathway: EPA is a competitive substrate for arachidonic acid in the COX-2 pathway, reducing the production of PGE₂ and the downstream NF-κB-mediated ubiquitin-proteasome protein degradation that typically accompanies muscle disuse or injury. Between training sessions, this anti-catabolic effect preserves muscle mass during recovery.
India's omega-6 dominance problem
The WHO recommends an omega-6:omega-3 ratio of 4:1 or lower. Most urban Indian diets — dominated by refined sunflower oil (containing ~45% linoleic acid omega-6), rice bran oil (~33% LA), and groundnut oil (~32% LA) — achieve a ratio of approximately 12–15:1.10 This excess omega-6 competes with EPA at COX and LOX enzyme active sites, blunting omega-3's anti-inflammatory effect. The practical consequence: supplementation dose may need to be at the higher end (3–4g EPA+DHA/day rather than 1g) for Indian lifters to achieve the intramuscular EPA and DHA concentrations seen in Western trial populations with lower baseline omega-6 intake.
Several popular Indian "omega-3" products — including plant-based capsules and flaxseed oil — provide alpha-linolenic acid (ALA), not EPA or DHA. Human conversion of ALA to EPA is below 5–10%; conversion to DHA is below 1%. ALA and EPA/DHA are not interchangeable for muscle protein synthesis. A product labelled "plant omega-3" or "omega-3-6-9" with linseed or flaxseed as the primary ingredient is an ALA supplement. Himalayan Organics Plant Omega 3-6-9 scores 4.1/10 on our rubric for this reason. Buy a fish oil with clearly stated EPA+DHA content — not "omega-3" content.
India brand comparison — Omega-3 EPA + DHA
| Brand & product | ₹ / 120 caps | EPA + DHA / cap | TOTOX tested | Our take |
|---|---|---|---|---|
| Carbamide Forte Triple Strength | ₹649 | 750 mg EPA+DHA | Not public | Best EPA+DHA per capsule. 3 caps reaches the 2g EPA+DHA threshold. Fewer caps, less fish oil taste. Verified brand. |
| WOW Omega-3 1000 mg | ₹499 | 600 mg EPA+DHA | Not published | Most popular on Amazon India. Accessible price. No public TOTOX data — the major gap. Adequate for budget tier. |
| Himalayan Organics Omega-3 | ₹549 | 600 mg EPA+DHA | Partial | Published COA; EPA+DHA stated clearly. Mid-tier quality with slightly better transparency than WOW. |
| Algal DHA (vegan) | ₹799 | 200–300 mg DHA only | No oxidation concern | Best vegan option — DHA from the same microalgae fish accumulate it from. EPA is absent or minimal. Adequate for cardiovascular purposes; less studied for muscle protein synthesis specifically. |
Target 2g EPA+DHA/day = 3–4 standard (600mg EPA+DHA) caps or 2–3 triple-strength (750mg) caps. Take with your largest meal for best bioavailability. TOTOX (oxidation index) should be <26 per GOED standard — most Indian brands have not published this data. See our fish oil freshness Q1 2026 batch testing →
Timing & daily schedule
Five compounds, two of which have meaningful timing requirements (whey post-workout; casein pre-sleep). The others are anchored to meals, not training windows. On rest days, drop the post-workout whey — casein and the carry-overs continue.
Monthly cost breakdown
Two tiers. The standard tier reaches the ₹3,260 headline. The budget tier makes sensible quality trades while keeping all four active compounds present at clinically studied doses.
If ₹3,260/month is too steep, cut the omega-3 first — drop to ₹2,900/month. Casein and whey have stronger direct lean-mass evidence per rupee spent. Add omega-3 back when budget allows. Do not cut casein to save money — it is the novel compound in this protocol and the one most responsible for the ₹3,260 vs ₹1,840 (Foundation Stack) cost gap.
Month 4+ — what to consider adding
The four compounds above carry a trained lifter through the first 16-week block. After that, the law of diminishing returns means genuine evidence-backed additions are fewer. The options below have RCT support but narrower benefit vs the core stack.
Beta-alanine (CarnoSyn)
3.2–6.4g/day raises intramuscular carnosine, the primary pH buffer in type IIa/IIx fibres, extending time-to-failure in 1–4 minute training sets. Meaningful for high-volume hypertrophy training (sets of 10–20 reps). 40+ RCTs. Effect is cumulative — takes 4–6 weeks to build carnosine stores.
Beta-alanine library entry →EAA intraworkout blend
All 9 essential amino acids (10–15g) sipped during training provides a full MPS substrate without relying on a post-workout shake window. Meta-analysis: EAAs stimulate MPS 50% more than BCAAs at equivalent leucine. Best for lifters training fasted or with delayed post-workout meals.
EAA library entry →Ashwagandha KSM-66
300–600mg KSM-66 significantly improved muscle recovery, testosterone, and strength vs placebo in Wankhede et al. 2015 (JISSN). Best for lifters with high training volume and elevated stress. Requires 8–12 week window to reach full cortisol-reduction effect. KSM-66 specifically — not generic ashwagandha powder.
Ashwagandha entry →Magnesium glycinate
200–400mg elemental magnesium glycinate pre-bed. Addresses deficiency common in Indian diets, improves sleep quality and overnight cortisol, and provides the glycine independently associated with improved sleep onset. Synergistic with the pre-sleep casein timing already in this protocol.
