Whey
(number of products: 107)Whey, or whey protein, is the most popular and best-researched protein supplement in the world. Obtained from milk during the cheese production process, it is characterized by a high biological value (BV), rapid absorption, and a complete amino acid profile, including a large amount of BCAAs (leucine, isoleucine, valine), which are essential for muscle building and recovery. If you train for strength, participate in martial arts, fitness, or simply lead an active lifestyle, Whey Protein will help you achieve better results, recover faster, and develop muscle mass more effectively without excess body fat.

Biotech USAWhat is Whey Protein?
Whey protein is not a synthetic invention from a laboratory. It is a 100% natural product, obtained from milk during the cheese-making process. Whey, once considered a by-product, has turned out to be a treasure trove of the most valuable protein fractions with an extremely high biological value.
Its phenomenon lies in several key features that make it the ideal protein for athletes:
- Complete Amino Acid Profile: Whey provides all nine essential amino acids (EAAs), which the body cannot synthesize on its own and must obtain from food. It is the complete building block for your muscles.
- Highest BCAA Content: Whey is the richest known source of branched-chain amino acids (BCAAs) – leucine, isoleucine, and valine. Leucine, in particular, is a key amino acid that acts as a switch for anabolic processes in the body, directly stimulating the mTOR pathway responsible for muscle protein synthesis.
- Rapid Absorption Kinetics: Unlike other protein sources like meat or casein, whey protein is digested and absorbed at a rapid pace. This causes a rapid and dramatic increase in amino acid concentration in the blood, creating a powerful anabolic signal, ideal for use around training. Rapid Absorption Kinetics: Unlike other protein sources like meat or casein, whey protein is digested and absorbed at a rapid rate.
- High Biological Value (BV): This indicator determines how effectively the body can use the supplied protein. Whey has one of the highest BV values, meaning that almost every gram of this protein is effectively used for building and regenerative purposes.
How do whey protein supplements work?
- Build muscle mass: supplements provide high-quality protein that supports muscle growth and regeneration after intense training.
- Accelerate your metabolism: thanks to the balanced content of nutrients, our products help maintain a healthy metabolism, which promotes faster fat burning.
- Faster training effects: protein supplements will become your ally on the way to achieving your dream figure and physical condition.
What protein supplements do we have?
- WPC - i.e. Whey Protein Concentrate, is a popular protein supplement of animal origin, which is produced through the process of draining whey during cheese production. It is rich in protein and also contains small amounts of fat and carbohydrates.
- WPI - i.e. Whey Protein Isolate, is a more purified form of whey protein. The production process removes most of the fat and lactose, making it more suitable for people who are lactose intolerant or looking for lower fat protein.
- WPH - i.e. Whey Protein Hydrolyzate, is a form of whey protein that has been subjected to the hydrolysis process, i.e. the breakdown of protein into smaller fragments (peptides) using water. This makes it easier to digest and absorbed by the body faster.
- Plant protein supplements - these are vegan proteins products that are an alternative for people who prefer a plant-based diet or have food intolerance to animal products. They can be made from plants such as soy, peas, hemp, rice or peas. They are rich in plant protein and often provide other valuable nutrients such as fiber, vitamins and minerals.

Benefits of using Whey Protein
Regularly incorporating whey protein into your diet brings a number of tangible benefits that directly translate into your athletic performance and physique appearance.
Maximizing Muscle Mass Growth (Hypertrophy)
This is the main reason why millions of athletes around the world reach for protein shakes. A rapid influx of amino acids, especially leucine, after a workout is the strongest known signal to initiate muscle protein synthesis (MPS). Regular stimulation of this process leads to effective muscle fiber growth, which translates directly into larger and stronger muscles.
Drastic Acceleration of Post-Workout Recovery
Intense training causes stress and micro-injuries to muscles. Rapidly providing them with building blocks in the form of amino acids from whey supplements allows for a rapid start to the repair processes. This results in a significant reduction in delayed onset muscle soreness (DOMS) and allows for a faster return to full fitness. Faster recovery means you can train harder and more often, which accelerates your progress.
Protecting Muscles from Catabolism
During periods of fat loss, when you're in a calorie deficit, your body can begin to draw energy from the breakdown of muscle tissue. This is the biggest enemy of a healthy physique. Whey protein, thanks to its anti-catabolic properties, helps protect hard-earned muscles, ensuring that the body burns primarily unwanted fat.
How to dose protein supplements?
To fully utilize the potential of whey protein, it's worth knowing the best time to consume it.
- Immediately after training: This is the most important time. Your muscles are like sponges at this time, extremely sensitive to nutrients. A WPI or WPH shake consumed within 30-60 minutes of exercise will instantly initiate the regeneration and growth processes.
- In the morning, after waking up: After a whole night without food, the body is in a state of light catabolism. Quickly absorbed whey protein will effectively stop this process and provide building blocks for the rest of the day.
- As a meal supplement: Have a meal low in protein, like oatmeal or salad? Add a scoop of this supplement to easily balance your macronutrients. A shake can also be a great, nutritious meal replacement when you're short on time.
- Between meals: To maintain a constant, elevated level of amino acids in the blood and prevent muscle breakdown throughout the day.
A typical single serving is approximately 25-40 grams of powder, which provides 20-30 grams of pure protein. This dose has been shown in studies to maximize stimulation of muscle protein synthesis.
How much protein powder per day?
It depends on your protein needs. A physically active person should consume approximately 1.6-2.2 g of protein per kilogram of body weight per day. Protein supplements are intended only to supplement your diet, not to replace protein from food. For example: if you weigh 70 kg and need 140 g of protein, and you get 100 g from food, you can supplement the missing 40 g with protein (i.e., about 1.5 servings).
How much is 30 g of protein supplement?
30 g of protein supplement (e.g., WPC/WPI) is usually 3 tablespoons. This serving provides approximately 20-25 g of pure protein (the rest is fat, carbohydrates, and flavorings). It's worth reading the product label – protein content may vary slightly depending on the manufacturer and scoop size.
What does protein do without exercise?
It won't build muscle, because the stimulus of training is needed. However: It supports recovery, helps maintain muscle mass during weight loss, can make you feel full, and supports healthy skin, hair, and nails.
How long does it take to see the effects of drinking protein?
Protein doesn't produce spectacular visual effects without proper training. If you use it as a dietary supplement + strength training: The first effects (increased strength, regeneration, improved physique) may be noticeable after 4–8 weeks of regular training and supplementation.
Can you drink protein every day?
Yes, you can. For many people, it's a convenient way to supplement protein in your diet. There are no contraindications unless you have kidney problems or a milk protein allergy (if it's WPC, for example). It's best to take it after training or when it's difficult to eat a full meal.
