People call Primo “mild,” but that label can be misleading. Compared with harsher compounds, it’s often better tolerated, yet it still alters hormones, lipids, and potentially liver markers depending on form and dose. “Worth it” hinges on your baseline health, goals, budget, and willingness to do proper labs with medical oversight. If a lean, steady look is the aim, disciplined nutrition and training deliver most of the outcome; any compound just nudges the last few percent—and with risks.
