What is Epoetin Alfa?
Recombinant human erythropoietin alfa is a glycoprotein hormone that stimulates red blood cell production. In endurance contexts, its main effect is improving oxygen delivery and potentially raising VO2 max, but the safety margin is narrow.
Key Benefits & Mechanisms
raises hemoglobin
increases oxygen-carrying capacity
may increase VO2 max
improves time-to-exhaustion
Research Summary
Human studies in anemia and performance-related settings show that increasing red-cell mass can improve aerobic capacity and endurance. It remains heavily regulated because excessive erythropoiesis raises thrombotic and cardiovascular risk.
Related Peptides
FS315
Follistatin-315 (FS315)
The circulating major isoform of follistatin that binds activins and can modulate myostatin signaling. It is widely used in research because it is the more common endogenous secreted form in human plasma.
Muscle & PerformanceACE-031
ACE-031 (soluble activin receptor type IIB-Fc)
A recombinant decoy receptor fusion protein that traps myostatin and related ligands such as activins. It was developed to promote skeletal muscle growth and counteract wasting.
Muscle & PerformanceBYM338
Bimagrumab (BYM338)
A human monoclonal antibody against activin type II receptors that blocks myostatin/activin signaling at the receptor level. It has been studied for sarcopenia, obesity with muscle preservation, and several wasting conditions.
Muscle & PerformanceREGN1033
Trevogrumab (REGN1033)
A human monoclonal antibody that neutralizes myostatin, the key negative regulator of skeletal muscle growth. It has been evaluated for muscle loss states and as a body-composition modulator in combination regimens.
