Here’s a breakdown of UPI Pharma Carbotein Mass Gainer — what it contains, how it works, and what to watch out for.

UPI Carbotein Mass Gainer is a high-calorie “mass-gainer” supplement from UPI Pharma — intended for people who want to gain weight and build muscle mass, especially “hard-gainers” who find it difficult to get enough calories or protein from regular meals.
The formula combines a protein blend (e.g. whey, casein, egg albumen / egg white) with complex carbohydrates, some healthy fats, BCAAs, vitamins & minerals — designed to support muscle recovery, growth, and overall nutrition when training intensively.
One serving (depending on how you mix it — often a “large shake / multiple scoops”) can deliver: ~ 1220 kcal, ~ 60 g protein, ~ 230 g carbohydrates, and ~ 5 g BCAAs.
Some other marketing info lists more conservative serving size: e.g. ≈ 660 kcal, 60 g protein, 85 g carbs, 5 g BCAAs + vitamins/minerals per serving.
The product often comes in a ~ 3.9 kg container that gives around 26 servings (in one size variant).
What this means: UPI Carbotein is a calorie-dense supplement — useful if you need many extra calories + proteins + carbs to support muscle gain and recovery.
Help you gain weight / bulk up / increase mass — by delivering extra calories + macronutrients.
Support muscle growth and recovery thanks to high-quality protein blend + BCAAs + nutrient mix.
Provide energy (carbs + calories) to sustain intense training and replenish glycogen, helpful especially if training or lifestyle demands high energy.
Convenient way to reach high daily calorie & protein intake — useful if you struggle to eat enough solid food.
Typically mixed with water, milk or juice. Many sources suggest “3 scoops (≈ 150 g)” or “6 scoops (≈ 300 g)” depending on how many calories / nutrients you need.
Because of high calorie load, many people use it post-workout, or as a meal replacement or between meals to ensure they hit their calorie/protein targets.
As with any mass-gainer: best results when combined with consistent resistance training (e.g. gym / weightlifting) and a relatively balanced diet.
Because the supplement is very calorie-dense, if you don’t train hard or eat too much overall, you might gain fat instead of lean muscle.
The “large serving” versions (300 g) are very heavy — may be hard on digestion; some may prefer splitting into smaller portions.
As for any supplement: it should not replace balanced meals (whole foods, vegetables, healthy fats, etc.), but rather complement them.
If you have any health issues (e.g. kidney, digestive, metabolic) — it’s wise to consult a doctor/nutritionist before regular use.
