Peptide therapy at both
Both companies discuss peptide therapy as part of their offerings, which can include compounds studied for recovery, growth hormone pathways, and other uses. It is worth keeping a neutral, evidence-aware view: many peptides marketed in this space lack large human trials, so any peptide protocol should be evaluated carefully with a qualified provider who can explain the evidence, monitoring, and risks. Neither company changes that basic reality.
