Hair shedding at month three: mechanism and time course — the long version

Hair shedding at month three: mechanism and time course — the long version Writing it up because I had to work it out twice and would rather nobody else did.

Reporting something rather than asking about it, in case the pattern is useful to anyone else.

Over 22 weeks I logged this consistently: date, dose, time of day, and a simple severity score from 0 to 4 for each symptom. That is 151 data points, all self-reported, all unblinded, and collected by someone who knew what he expected to find. Treat it accordingly.

The reason I am posting is that my experience does not match the shape people usually describe here, and I would like to know whether that is unusual or whether the usual description is just the loudest version.

Worth separating two things that the opening post runs together.

Nausea: the most common side effect and the most dose- and titration-dependent one. It is usually most prominent in the first 24 to 48 hours after injection and attenuates as the dose is held stable. At each escalation step it often resets briefly before attenuating again.

Worth separating two things that post #8 runs together.

Lean mass loss: the rate of lean tissue loss depends on protein intake, resistance training volume, and total energy deficit. Adequate protein and maintaining training intensity both help preserve lean mass during weight reduction.

Delayed gastric emptying: the mechanism behind much of the gastrointestinal side-effect profile. At extreme magnitudes, severe gastroparesis is a rare but serious complication. Distinguishing ordinary gastrointestinal effects from the rare severe end is a clinical judgement.

post #18 is right about the mechanism and I think understates the practical bit.

Constipation: common, manageable, and frequently under-reported because it is not dramatic. Increasing fibre and fluid intake helps. Over-the-counter management is usually effective. This is worth addressing proactively rather than waiting for it to worsen.

Recognition and grading: nausea ranges from "noticeable" to "limiting". Constipation ranges from mild to severe. Having language to describe the magnitude helps you track whether something is worsening or stable and helps your clinician understand what you are reporting.

Coming back to post #30, because the follow-up matters more than the original answer.

Pancreatitis: a rare but serious event with a specific presentation (epigastric pain, back pain, elevated lipase). If this constellation of findings appears, stopping the drug and seeking immediate evaluation is appropriate. Do not interpret this as "likely" — it is rare — but recognize the pattern if it appears.

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.
