"Plant-based protein for muscle recovery"
Pea protein at 20-30g per serving supports muscle protein synthesis comparably to whey. Bioavailability is moderate and lower in older adults.
PubMed: Pea Protein clinical trials -
"Moderate pricing for plant-based protein"
At $2.25/serving, markup is 2-4x wholesale cost. Comparable to Orgain ($25-30) and Vega ($30-35) for similar quantity.

"Build a bigger booty with protein powder"
Protein supports muscle recovery during training. Booty growth requires progressive resistance training and calorie surplus, not powder alone.

"No Supplement Facts label disclosed on product page"
Cannot verify protein content per serving, amino acid profile, or ingredient amounts. Label transparency is required for informed purchasing.

Consumer advice
If you're already training consistently and eating in a calorie deficit, this protein powder will help you meet your daily protein target (aim for 0.7-1g per lb of body weight). Don't expect the powder alone to build a bigger booty or burn fat—those results come from progressive resistance training and a calorie deficit. The subscription saves 10% and includes free shipping, which is a fair deal if you plan to use it regularly. Compare the per-serving cost to Orgain or Vega before committing. The "free gifts" (shaker, ebook, etc.) are marketing tactics to increase perceived value; they're nice but don't change the core product quality.
