In this clip from Bathroom Diaries, Dr. Sofia Din and Dr. Rob Frankel break down one of the most common mistakes people make with peptides: thinking one peptide can fix everything. Using a simple and hilarious analogy — "asking for one peptide is like going to a tire shop and buying just one tire" — they explain why peptides work best as a system, not a single quick fix. If you're curious about how peptides actually work, which combinations make sense, and why personalized protocols matter, this highlight is a must-watch.

📌 In this clip: • Why "one peptide" doesn't work

• How peptides function together

• Why stacking peptides is more effective

• The logic behind personalized protocols

• The tire shop analogy that makes it all click
