RULE 1 Source 7 Protein 1800g – protein supplement for professionals
RULE 1 Source 7 Protein 1800g is a protein supplement created for people who want to fully utilize their training potential. The advanced composition combines as many as 7 protein fractions with varying absorption rates, supporting the body from the first minutes after training until nighttime regeneration.
As many as 7 protein sources that care for your muscles all day long
By combining isolate, hydrolysate, concentrate, as well as micellar casein and pea protein, each serving works in multiple stages. The body receives both instantly acting amino acids and slow-absorbing ones that work for many hours.
RULE 1 Source 7 protein is:
- 22 g of protein in every serving
- 7 complementary protein sources
- high EAA and BCAA content
- great solubility and creamy consistency
- Informed Choice® certificate
- support for muscle building and fat reduction
Source 7 protein supplement was designed by specialists from the RULE 1 brand – a company known for transparent compositions, the highest quality raw materials, and Informed Choice certification, confirming product purity.
Taste and consistency of RULE 1 Source 7 Protein
Let's be honest, how many times have you bought protein that tasted like concrete? A gritty consistency and a taste that was far from a good quality shake.
The RULE 1 Source 7 Protein supplement will completely erase those bad memories. The use of innovative micronization technology and the addition of pea protein resulted in a dense, creamy, and velvety consistency. This is not a watery drink – you get a delicious shake that is more like a dessert.
- No more clumps: The powder dissolves excellently, even in a regular shaker.
- Dietary pleasure: The taste of this protein makes you drink it with pleasure.
- Curb sweet cravings: Thanks to its excellent taste, the shake effectively replaces unhealthy sweets, helping you stick to a "clean diet" without sacrifice.
Why do your muscles need good quality protein?
The human body is a complicated machine. After intense physical exertion, it needs an immediate "injection" of amino acids to stop the process of muscle fiber breakdown (catabolism). However, this is only the beginning. Repair processes last for hours, or even days. If you only provide yourself with fast-absorbing isolate, your muscles may starve again after an hour. This is where RULE 1 Source 7 Protein comes to the rescue.
Thanks to the blend of proteins with different absorption rates, you receive:
- Immediate start of regeneration right after drinking the shake.
- Stable amino acid concentration in the blood for a long time.
- Muscle protection during periods when you cannot eat a meal.
RULE 1 Source 7 Protein, what protein fractions are in the supplement?
Fast-absorbing protein
The composition includes:
- whey protein hydrolysate (WPH),
- whey protein isolate (WPI),
- native whey protein isolate.
These three fractions are absorbed within 30–60 minutes. After heavy sets of squats or deadlifts, the body immediately receives building blocks to repair micro-damage. The effect? Fewer "soreness" the next day and a faster return to full strength.
Medium-absorbing protein
Whey protein concentrate (WPC) and milk protein isolate act as a bridge. When the fast fractions are depleted, they continue to supply amino acids. This is ideal between meals or at work when you cannot eat a full lunch.
Slow protein absorption in Source7
Micellar casein and pea protein are the true guardians of your muscle mass. They release amino acids slowly, so your body doesn't reach for its own muscles as an energy source at night. You wake up rested and ready to go in the morning.
The impact of the amino acid profile on your results
Not all protein is created equal. Its value is determined by its amino acid profile. The product discussed is a powerful amino acid bomb. Each serving contains over 10 grams of essential amino acids (EAA), which your body must obtain from food because it cannot produce them itself.
Leucine – the anabolic trigger for your muscles
Particular attention should be paid to the high content of BCAA (branched-chain amino acids), especially leucine. In exercise physiology, we talk about the "leucine threshold." To initiate the synthesis of new muscle proteins, the cell must receive a sufficiently strong signal. Leucine is just such a signal – a switch that tells your body: "start building and repairing." Thanks to the presence of fast whey fractions in RULE 1 Source 7, this signal is sent almost immediately after consumption.
Regeneration of tendons and joints
It is worth remembering that amino acids are not only for muscles. They are essential for collagen production, and the regeneration of tendons, ligaments, and skin. Comprehensive delivery of building blocks thus supports the entire musculoskeletal system, which is crucial for avoiding injuries under heavy training loads.
Informed Choice Certificate – guarantee of safety and purity
Quality is not just a nice package and marketing promises. It is primarily the certainty that what you put into your body is safe. We live in a time where supplement contamination happens alarmingly often.
By choosing RULE 1 Source 7 Protein, you choose peace of mind. The product has the prestigious Informed Choice® certificate. What does this mean for you?
- Rigorous testing: Every batch of the product is tested by an independent, world-class laboratory, LGC, for the presence of prohibited substances.
- Anti-doping safety: Regardless of whether you are a professional athlete subject to controls or an amateur concerned about health, you have the assurance that the supplement is free from steroids, stimulants, and other illegal additives.
- Trust: The Rule 1 brand builds its position on transparency and honesty towards the customer.
How to dose Source7 supplement to maximize its potential?
1 serving, 39 g, mix in 250 ml of water.
The versatility of this product means you can use it in almost any situation. Here are the scenarios where it works best, based on the experience of trainers and dieticians:
- Morning metabolic kick-start: After a night's sleep, your body is in a state of catabolism (breakdown). Drinking a serving of protein with breakfast, e.g., with oatmeal, provides fast amino acids for the start and slower-release fractions that will provide energy for the next hours of work or study.
- Post-workout period: This is the most important time of day for your physique. Your muscles soak up nutrients like a sponge. Thanks to the hydrolysate and isolate, Source 7 instantly initiates the repair of micro-damage caused by weightlifting.
- During the day: A busy lifestyle often makes it impossible to eat a complete meal. A protein shake is the ideal "on-the-go" solution. Pea protein and casein will provide a feeling of satiety, stabilizing blood sugar levels and preventing episodes of ravenous hunger, which is crucial during fat reduction.
- Nighttime protection: Drinking a shake 30 minutes before sleep is an excellent way to utilize the potential of micellar casein. While you sleep, your body has constant access to amino acids, allowing for calm and deep regeneration. You will wake up less sore and more ready to go in the morning.
