The Stack
Three vegan proteins covering different needs: a daily complete blend, a high-volume pea isolate, and a smoothie-friendly organic option.
21g protein from a pea-and-brown-rice blend with added chia and flax. USDA Organic, complete amino acid profile, decent leucine content.
See live price →25g of pure pea protein isolate in unflavored form. Highest protein-per-dollar in the plant category and easy to add to smoothies or oatmeal without adding flavor.
See live price →20g of plant protein from KOS at the entry-level price point. Useful for stocking your second tub or adding a different flavor in week three of your block.
See live price →Why This Combo
Plant bulking gets harder than whey bulking for two reasons: lower leucine per scoop and worse digestibility. This stack fights both.
- Orgain has a complete amino acid profile. Pea protein alone is low in methionine. Rice protein alone is low in lysine. Orgain blends them, which gives you the closest plant-based equivalent to whey's complete profile.
- MyProtein Pea Isolate is your high-volume workhorse. At 25g per scoop and 76 cents per serving, it's the cheapest way to add protein scoops without spiking cost or adding sweetener load.
- KOS Organic adds variety so you don't burn out. Bulking takes weeks. The same vanilla shake every day kills compliance. KOS swap-in days break that monotony.
Total Monthly Cost
Math: 25 servings of Orgain (daily shake) + 20 servings of pea isolate (post-workout) + 14 servings of KOS (variety):
| Daily plant blend: Organic Plant-Based Protein (25 servings/mo) | $26.91/mo |
| Pea isolate (volume): Pea Protein Isolate (20 servings/mo) | $15.15/mo |
| Organic backup: Organic Plant Protein (14 servings/mo) | $17.29/mo |
| Total monthly cost | $59.35 |
That's about $59/month for around 1,300g of high-quality plant protein. Add another 80 to 120g daily from food (lentils, tofu, tempeh, edamame) and you'll easily hit 180g+ on a vegan bulking diet.
How to Use Each
Orgain Organic Plant-Based (daily)
One scoop in 8 oz oat milk or almond milk in the morning. Orgain is sweetened with stevia and has a slightly chalkier texture than whey, so blending with banana or oats helps.
MyProtein Pea Protein Isolate (post-workout)
Unflavored, so mix one scoop into a smoothie with fruit and a sweetener of your choice. 25g per scoop with effectively zero fat or carbs makes this the lowest-calorie, highest-protein plant option per scoop.
KOS Organic Plant Protein (variety)
Use this on days you'd otherwise skip a shake out of boredom. KOS has a creamier texture from added coconut and a different sweetener profile (monk fruit + stevia) than Orgain.
Cheaper Alternatives
- Swap Orgain for Sports Research Plant Protein at $29.95. Similar pea+rice blend, USDA Organic certified.
- Swap MyProtein pea isolate for Now Sports Pea Protein at around $25/2 lb. Same isolated pea source.
Upgrade Path
- Upgrade Orgain to Garden of Life Raw Organic Protein for added probiotics and digestive enzymes.
- Upgrade KOS to Vega Original Plant Protein for the long-running benchmark plant protein with added superfoods.

Yes. A 2019 study by Babault et al showed pea protein and whey produce equivalent muscle thickness gains over 12 weeks at matched doses. The catch is dose: you may need slightly more grams of plant protein per day to hit equivalent leucine targets, but the muscle-building outcome is the same.
Because plant protein flavors and textures vary more than whey. Vegan lifters who try to do everything from one tub usually quit after week three out of boredom. Rotating two or three keeps compliance high across a multi-week bulking block.
For a small lifter (under 150 lb), maybe. For a larger lifter targeting 180g+ protein per day, pea alone is suboptimal because of its lower methionine content. Pairing with rice protein (as Orgain does) creates a more complete amino acid profile.
Soy is the most complete plant protein and is fine for vegan bulking. We didn't include a soy-only pick here because the highest-rated soy isolates (NOW Foods, Naked) carry similar price tags to whey, while the pea-rice blends are cheaper and just as effective.
Sometimes more, actually. Pea protein is denser and slower-digesting than whey. Many vegan lifters report longer satiety from a pea shake than a whey shake, which is helpful when bulking on a tight schedule.
If your daily protein is around 1.6 to 1.8g per pound and spread across four to six meals, no. If you're concerned, an extra 5g leucine before training is cheap and well-tolerated. But for most vegan lifters, hitting daily protein totals matters far more than chasing per-meal leucine numbers.
