Follistatin-344 is a full-sized synthetic analogue of naturally occurring Follistatin. It neutralizes the effects of myostatin, activin, and follicle stimulating hormone (FSH). In animal studies, these actions lead to increased muscle mass (both hypertrophy and hyperplasia), reduced scar formation, and inhibited certain inflammatory responses. Follistatin-344 can be altered by the body to produce other variants of Follistatin. Follistatin-315 is a naturally occurring activin and myostatin binding protein. It improves muscle growth (both hypertrophy and hyperplasia), fights inflammatory responses, and boosts fertility. Follistatin-315 is the most abundant form of the glycoprotein found in blood plasma. Dosing: 100mcg-200mcg Frequency: 1-2 times per week Cycle: 10-30 days
