Model overview based on user reviews
Optimum Nutrition Serious Mass is a popular choice among those looking to gain weight, especially for hardgainers and ectomorphs. Users appreciate its convenient large measuring scoop and delicious taste, often compared to a chocolate milkshake. The product is noted for its high carbohydrate content and 50 grams of protein per serving, making it a substantial addition to one's diet. It also includes a comprehensive vitamin and mineral complex and a small amount of creatine, which some users find beneficial for energy and workout performance. However, the product is considered expensive and tends to run out quickly, with some users finding it challenging to consume in full servings. Despite these drawbacks, it remains a favored option for those struggling to gain weight, although it is emphasized that it should supplement, not replace, regular meals.
Pros
Cons
For those who are thin, those who don't have the time or desire to eat a lot. Tastes okay, almost like cocoa. Expensive and doesn’t last long use Optimum Nutrition Serious Mass 5.44 kg few months |
I’ve tried different gainers, both expensive and not expensive, this one is really the coolest. Do not forget that this is an addition to the main diet, and not a replacement for it (I took half a dose after training and it was enough) Very tasty, doesn’t get boring, good for weight gain high price |
When I first started going to the gym, I immediately began searching for some sort of "magic pill" — "I'll drink this and build muscle." I watched tons of videos with advice for skinny people and those who have trouble gaining muscle mass. Many recommended getting a gainer at the beginning. You can't overdo it with carbs (there's no fat anyway), plus protein for muscle growth. I decided to buy this product from the most promoted and popular brand. I got a 5-kilogram bag — it lasts for half a month. The measuring scoop, as always, is somewhere at the bottom, in the powder. One serving is enormous — 334 grams! I had trouble eating regular food, and here comes this overly sweet, rich, filling shake. It was basically a full meal for me. After drinking it a couple of times, I started splitting it into two portions. I drank one in the morning instead of breakfast, and the other after a workout. In terms of taste, it's like a milkshake (chocolate) from McDonald's. Very tasty (half a scoop per 300 ml of milk). Nutritious, a good addition to the diet, but again — it's for ectomorphs to drink. The composition is a classic gainer with a tilt towards carbs. A full serving gives 50 grams of protein. That's not bad if you struggle to get enough with regular food. A pleasant addition is the vitamin and mineral complex. It's really comprehensive, no need to take additional supplements. There's also creatine in it, 1 gram — not much, but it helps a little. Vitamins plus creatine, as my friend would say, "give a boost." The slightly higher norm of B vitamins provides a burst of energy, and creatine adds a couple of reps to your set. convenient large measuring scoop. - runs out quickly :( |

Lasted for a month.
I gained 1 kg, which is of course a bit low... Maybe I need to purchase enough for at least 3 months, but that's not a small expense. I'll update here if I decide to proceed.
