How often are peptides dosed?

Half-life sets the interval

A compound cleared in under an hour cannot hold a steady concentration on weekly administration, which is why several growth-hormone secretagogues appear in multiple-times-daily schedules. Engineered incretins carry structural modifications that extend half-life to days, which is what makes once-weekly administration coherent for them.

That is also why frequency and amount are separate questions. Two schedules can deliver the same weekly total and behave differently, because what changes is the shape of the concentration curve rather than the quantity.

What titration is for

Where a schedule escalates in steps rather than starting at its maintenance figure, that is usually tolerability rather than efficacy: the published rationale is generally that starting high raises side-effect rates without improving outcomes. The escalation is a property of the published protocol, not a rule about how anything ought to be approached.

Where no trial established a schedule

For most research peptides no completed human trial fixed an interval, and what circulates instead is a convention — a practice that repeats, not a finding. Prof. Peptide reports those conventions and says plainly that they are conventions. Where a half-life has been measured, that measurement is the one piece of evidence a frequency claim can actually be checked against, so the per-compound pages lead with it.
