Using the FitScience research library
Where should I start with peptides?
Start with the peptide research guides, then use the comparison tables to find individual compounds and their references.
How should I assess a research claim?
Check the original study, who or what was studied, the outcome measured and the limitations. Distinguish findings in cells or animals from findings in human studies, and distinguish evidence from speculation.
Where can I compare SARMs?
The SARMs research tables link into compound profiles. Read the underlying references and limitations alongside any comparison.
