Follistatin

$135.00

Follistatin is a naturally occurring protein that inhibits myostatin, a regulator that limits muscle growth. By blocking myostatin, Follistatin promotes rapid muscle hypertrophy, strength gains, and improved recovery. It also plays a role in tissue repair and anti-aging processes, making it a sought-after peptide in bodybuilding and regenerative medicine. Unlike anabolic steroids, Follistatin increases muscle mass without androgenic side effects, making it ideal for those looking to enhance muscle growth naturally. It has also been studied for its potential in improving tendon and joint health, making it valuable for athletes and aging individuals seeking injury prevention and faster recovery.

Rapid Muscle Growth

Follistatin inhibits myostatin, a protein that limits muscle development—unlocking the potential for dramatic hypertrophy beyond natural genetic barriers. It’s highly effective for anyone aiming to accelerate lean muscle gains, especially when combined with strength training and a high-protein diet.

Enhanced Recovery Support

By regulating growth factors like activin and myostatin, Follistatin promotes faster repair of muscles, tendons, and joints. This makes it ideal for post-injury recovery or for athletes pushing their training limits, helping reduce downtime and support long-term structural health.

Stacks for Synergy

Follistatin pairs exceptionally well with IGF-1 LR3, MGF, and growth hormone peptides. Together, they amplify anabolic signaling, enhance protein synthesis, and improve overall recovery. This makes it a powerful stacking option for advanced users aiming for rapid, sustainable progress.

Short Use, Big Gains

Even with brief cycles, Follistatin delivers noticeable increases in muscle mass and strength that persist long after use. It offers a strategic, low-frequency alternative to traditional anabolics, helping users achieve physique goals without prolonged or continuous use.

Side Effects + Considerations

Follistatin is well-tolerated, but some users report temporary joint discomfort due to rapid muscle growth outpacing tendon/ligament adaptation. Excessive doses may lead to uncontrolled muscle growth, creating muscle imbalances if not paired with proper training. Some users experience fatigue, mild inflammation, or injection site irritation. Long-term effects are not well-documented, so use should be limited to short, controlled cycles. Because it influences muscle gene expression, users should carefully monitor their response.

Our Guide to Intramuscular Injection

Gather Your Equipment

Before you begin your injection, make sure all your supplies are organized and within reach. You’ll need the injectable compound, a clean single-use syringe and needle, alcohol pads, a proper sharps disposal container, cotton balls or gauze for cleanup, and optionally, a mirror if you’re injecting yourself. Having everything set up in advance helps the process go smoothly without unnecessary interruptions. Prioritizing preparation and safety supports proper technique and long-term well-being.

Compound Extraction

After gathering all the required items, it’s time to draw the medication from the vial. Hold the vial upright and gently pull back on the plunger to fill the syringe with the exact amount prescribed. Make sure to follow your healthcare provider’s directions precisely. Once filled, tap the syringe lightly to bring any air bubbles to the top. Then, carefully press the plunger to expel the air, stopping when only the prescribed amount remains. Review the recommended injection depth before continuing.

Preparation Before Injection

To begin, select a clean, bright space where you can work comfortably. Wash your hands thoroughly with soap and water to prevent contamination. Then, prepare the injection site—this may be your thigh, glute, or upper arm, depending on your provider’s guidance. No matter the location, clean the area using an alcohol swab to eliminate oils, debris, or bacteria. Let the area air dry fully before proceeding to the injection.

Compound Administration

With the syringe ready, you can now give the injection. Grip the syringe securely and insert the needle into the chosen site at the correct depth. Gently pull back on the plunger—if blood enters the syringe, remove it and start again with a new needle. If no blood appears, push the plunger slowly and steadily to deliver the medication. A gradual injection helps maintain comfort and control. Once the dose is fully delivered, remove the needle carefully and dispose of it safely.

Safe Disposale of Needle Tips and Syringes

Ensuring the proper disposal of utilized syringes and needles is crucial for the safety of yourself and those around you. Once used, promptly deposit the syringe and needle into a designated sharps container. Avoid recapping the needle to prevent unintentional needle pricks. Familiarize yourself with the regulations in your local area concerning the appropriate disposal of medical waste. Numerous regions have specific guidelines for discarding sharps containers, and adhering to them is vital to safeguard both your community and the environment.

Incorporate Follistatin Into a Stack

Follistatin is often stacked with IGF-1 LR3 or PEG-MGF to amplify muscle recovery and hypertrophy. It pairs well with CJC-1295 and GH peptides for overall tissue repair and anti-aging benefits. For users seeking maximum muscle gain, it can be combined with SARMs (like YK-11, which also inhibits myostatin) or anabolic steroids. Because Follistatin use is short-term, it should be cycled properly to avoid desensitization. Best results come from high-intensity resistance training combined with a high-protein diet.

Side Effects + Considerations

Follistatin is well-tolerated, but some users report temporary joint discomfort due to rapid muscle growth outpacing tendon/ligament adaptation. Excessive doses may lead to uncontrolled muscle growth, creating muscle imbalances if not paired with proper training. Some users experience fatigue, mild inflammation, or injection site irritation. Long-term effects are not well-documented, so use should be limited to short, controlled cycles. Because it influences muscle gene expression, users should carefully monitor their response.

Usage Guidelines For Follistatin

Follistatin is injected intramuscularly or subcutaneously once per day for short-term use (typically 7-10 days per cycle). The most common dosage protocol is 100mcg to 300mcg daily for a 10-day cycle, followed by a break to prevent receptor desensitization. It is most effective when paired with resistance training, particularly progressive overload and hypertrophy-focused workouts. To minimize joint discomfort, users should ensure proper warm-ups, mobility work, and hydration. Store at 2°C to 8°C (36°F-46°F) after reconstitution with bacteriostatic water.

Consult With a Healthcare Provider

Before considering the use of anabolic steroids, it’s important to speak with a licensed medical professional. They can assess your overall health, explain the potential benefits and risks, and provide tailored advice that fits your personal goals and medical history.

Choose Reputable, Quality Sources

To minimize the risk of contaminated or fake products, always source anabolic steroids from reputable vendors. Stick to well-known suppliers who follow strict quality protocols and have earned a solid track record within the fitness or medical community.

Begin Conservatively

TWhen starting anabolic steroids, begin with the lowest dose that may offer results. Increase gradually only if necessary, paying close attention to how your body responds and watching for any unwanted effects along the way.

Implement Effective PCT

After finishing a steroid cycle, proper post-cycle therapy is essential. It helps normalize hormone levels, reduce side effects, and maintain the health benefits gained. Skipping this step can compromise both progress and well-being.

Side Effects + Considerations

Anabolic steroids present substantial health risks that necessitate careful consideration. Consult healthcare professionals before use to comprehend potential adverse effects, including cardiovascular issues, hormonal imbalances, and psychological impacts. Strictly adhere to prescribed dosages and durations while prioritizing regular health monitoring. Adolescents should refrain from using these substances due to potential growth interference. Opt for alternative fitness methods to prioritize overall health and well-being, and always use under professional supervision.

The use of anabolic steroids demands thoughtful consideration due to serious health risks. Seek guidance from healthcare professionals before embarking on their use to fully understand potential adverse effects. Strictly adhere to prescribed dosages and durations, prioritize regular health monitoring, and avoid use by adolescents to prevent potential interference with growth. Explore alternative fitness methods that prioritize overall health and well-being, and use anabolic steroids only under the supervision of qualified professionals.
