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.
Generic Name:
Follistatin
Compound Information:
Molecular Weight: 31.5 kDa (Follistatin 344)
Formula: C699H1116N206O224S6
Anabolic Rating: High
Androgenic Rating: N/A
HOW MUCH YOU’LL NEED
SUGGESTED ORDER AMOUNT
At a standard dose of 200mcg per day, one 1mg vial lasts approximately 5 days during a blast cycle. A common approach is 2–3 vials per person for a full 10–14 day blast, with additional vials recommended if stacking with BPC-157 or TB-500 for connective tissue support.
Dosage (Male)
100mcg to 300mcg per day
Dosage (Female)
50mcg to 200mcg per day
Dosage Frequency
Once daily (for short-duration cycles)
Dosage Type
Intramuscular or Subcutaneous Injection
01
Draw 1.0 mL of Bacteriostatic Water USP from the vial.
02
Carefully inject the Bacteriostatic Water into the Follistatin-344 vial, aiming the stream along the side of the vial and avoiding direct contact with the lyophilized powder.
03
Gently swirl the vial until the powder is fully dissolved and the solution becomes clear. Do not shake the vial vigorously.
04
Once mixed, the concentration will be 1mg (1000mcg) per mL (1mg per 1mL vial), equating to 100mcg per 10 units on a standard insulin syringe. Remember, 100 units on the syringe equals 1mL, corresponding to 1mg of Follistatin.
05
The prepared solution can be administered subcutaneously (SubQ) in the lower abdominal fat area or via shallow intramuscular (IM) injection into the target muscle group.
06
Once reconstituted with Bacteriostatic Water, the solution should be stored in the refrigerator. Use within 60 days to ensure potency and effectiveness.
WHEN TO TAKE it
Follistatin is most effective when administered immediately following your workout. Myostatin levels naturally spike after heavy resistance training — dosing post-workout allows Follistatin to suppress that spike precisely when your muscles are primed for repair and growth.
While Follistatin works systemically, many users prefer intramuscular (IM) injection into a lagging muscle group such as delts or calves, immediately after training that specific muscle. This can provide a localized recovery effect while systemic inhibition supports the rest of the body.
Follistatin is used in short, focused cycles rather than continuous use. Running it continuously leads to diminishing returns — a short, high-intensity blast followed by a sufficient break is the most effective approach to unlocking new muscle growth.
RECOMMENDED SCHEDULE
- Low Dose (100mcg — 10 units): Ideal for assessing tolerance or long-duration muscle maintenance
- Standard Dose (200mcg — 20 units): The most common dose for significant myostatin inhibition and muscle support
- High Dose (500mcg — 50 units): For intensive, short-term hypertrophy protocols
- Blast Cycle: Once daily for 10–14 days, repeated no more than once every 2–3 months
- Extended Growth Protocol (30 days): 50–100mcg daily for slow, steady myostatin suppression and a sustained anabolic state
Consult With a Healthcare Provider
Before considering the use of peptides, 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.
Begin
Conservatively
When starting peptides, 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.
PRIORITISE RECOVERY & MONITORING
Peptide protocols should be supported by proper recovery and regular self monitoring. Prioritizing sleep, nutrition, hydration, and stress management helps maximize results while reducing the risk of unwanted effects. Allowing adequate time between cycles supports long term metabolic health and overall well being.

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.
Our Vision
10+ Years of Peptide Expertise
At Pacific Peptides our mission is to offer you access to the highest quality peptides, helping you achieve the physique and fitness goals you’ve always dreamed of. Each of our peptides is designed to enhance overall well-being, boost performance, and promote vitality. With over ten years of experience in peptide formulation, Pacific Peptides offers a wide range of products to help you reach your full potential.
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.
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.
