Decision Guide

How to Choose

Neither is a “winner” — they suit different goals. Compare the documented benefits and evidence above against what you’re actually trying to achieve, note the research status (approved vs research-stage), and read each full guide before deciding. Many people also stack peptides rather than pick one.
