Short answer

Semaglutide has a long half-life on the order of about one week in pharmacokinetic labelling for weekly products, so it takes several weeks after the last dose for levels to fall substantially — often discussed as around five half-lives for practical washout, which lands near five weeks for many people. Exact timing varies with kidney function and individual factors. This is label/PK context, not a personal prediction. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.

What that means in practice

Appetite and side effects may fade gradually rather than overnight after stopping. Some writers describe food noise or weight regain in the weeks after discontinuation — anecdotes on the semaglutide hub. Surgery, pregnancy planning or switching drugs are clinician decisions that may use washout guidance from the label or specialist advice.
