Follistatin (FST)

Follistatin is a naturally occurring glycoprotein that binds and inhibits myostatin, the protein responsible for limiting muscle growth. By blocking myostatin signalling, it is studied for its potential to support lean tissue gains beyond what training and diet alone typically produce. This Syncom Labs vial contains 1mg of Follistatin for research use.

As a guide and not medical advice, research literature commonly references around 1mg injected intramuscularly every 3 days for a short protocol of roughly 4 weeks. Doses beyond this are not supported by available data and are not advised. Anyone considering use should speak to a qualified medical professional first and monitor closely for adverse reactions.

Reported effects include a possible rise in blood pressure, joint discomfort linked to rapid muscle growth, and general fatigue or lethargy. Long-term effects on organ health are not well documented, which is part of why this is treated as a research compound rather than an established one. Baseline and on-cycle bloodwork covering kidney and liver function, lipid panel, and blood pressure is a sensible precaution.

No. Its potency combined with a lack of long-term safety data makes it a poor starting point for anyone new to peptides. Those looking for recovery or tissue support with a milder profile are usually better served starting with something like BPC-157 or TB-500 before considering Follistatin.

There is no mandatory support compound required alongside Follistatin, though a solid diet and training programme is essential to make use of the added lean tissue potential. Some research protocols pair it with testosterone as an anabolic base, sometimes alongside cardarine to help manage cholesterol shifts during use. These are optional considerations, not requirements.
