Instructor Notes — Chapter 38

What this chapter is doing

Chapter 38 is not a law chapter. It is an epistemics chapter that happens to use regulation as its material. The single learning outcome that matters is that students stop treating regulatory status as a proxy for evidence — in both directions. Everything else is scaffolding.

Expect two populations in the room, and expect them to make opposite mistakes. Students who trust institutions will read "approved" as "proven." Students who distrust them will read "not approved" as "suppressed." The chapter is built to disappoint both, and the discussion works best when you get both errors said out loud early so the class can watch them fail together.

Prerequisites and where to place it

Prerequisites are Chapters 19, 6, and 12. Chapter 5 (the method) and Chapter 17 (BPC-157) are used so heavily that students who have not read them will be lost in §38.4 and §38.8. Chapter 16 (surrogate endpoints) makes §38.3's accelerated-approval material land; without it, that passage reads as housekeeping.

Timing. In a fourteen-week course, this is one week with §38.4 and §38.10 as the graded material. If you have only one session, teach §38.4 and §38.10 and assign the rest.

The three anchors

1. The number. The forty-amino-acid line is the most concrete regulatory fact in the book and the best available demonstration that a definition can be a policy instrument. Put the residue counts on the board — 9, 15, 31, 34, 39, 51, 191 — and draw the line between 39 and 51 before you say what it means. Students reliably guess the line has something to do with size in daltons; the insulin (5,800 Da, biologic) versus semaglutide (4,100 Da, drug) pair kills that guess in ten seconds and the lesson sticks because they were wrong out loud.

2. The taxonomy. The five meanings of "not FDA approved" is the chapter's exportable tool. Students will use it long after they have forgotten what a BLA is. Drill it until assignment is automatic.

3. The independence pair. BPC-157 is rated ❌ and prohibited under S0, for entirely unrelated reasons. This is the chapter's thesis compressed into one molecule. If a student can hold both facts without either one leaning on the other, they have the skill.

Predictable difficulties

"If it's prohibited in sport, that means it works." The most common error in the performance track, and it survives being addressed once. It needs to be named, refuted, and then re-elicited later in the session, because students will reconstruct it. The refutation is structural: S0's text contains no clause about efficacy, and the compounds it captures are captured because nobody knows whether they work.

Conflating "the sponsor stopped" with "the agency rejected." Case study 2's bremelanotide entry is built on this distinction and students will slide past it. It is worth a full five minutes, because the same sloppiness produces most of the "the FDA banned it" claims they will encounter.

Treating off-label as a euphemism. Students often hear "off-label" as a soft way of saying "unapproved and dodgy." Correct this with the pediatric and oncology examples: enormous quantities of well-supported medicine are off-label because nobody had commercial reason to file.

Wanting a legal answer. Someone will ask what they, personally, can legally buy or import. Do not answer. Model the refusal the chapter models: name the structure, decline the application, and point to a qualified source in their jurisdiction. This is itself a teachable moment about the difference between explaining a system and advising within it.

Date decay. Every specific rule in the chapter is date-stamped for a reason. If you are teaching this more than a year or two after publication, spend the first five minutes checking the current WADA List and the current status of the compounding provisions, out loud, in front of the students. It is the single most valuable thing you can demonstrate.

Assessment notes

• The quiz's items 11, 21, and 22 are the load-bearing ones. Item 22 is the best single discriminator in the chapter's assessment set.
• Exercises R, V, AF, AG, AM, and AN map directly onto the learning objectives. AM is the hardest and the best essay prompt.
• For dossier work, grade the separation of columns, not the accuracy of the status lines. A student who records the wrong List year but keeps status and rating rigorously apart has learned the chapter; a student with perfect status lines and a rating softened by a foreign approval has not.
• Watch for students who fill Field 10 by copying seller marketing. The "how is it actually being sold" line is designed to catch this: it asks about the channel, and the honest answer for most Part III compounds is unflattering.

A note on tone

The chapter refuses two positions that many students hold as identity commitments. Handle it as the chapter does: attack the inference, never the person, and be conspicuously willing to say that approval is genuine information and that the funding gap is a genuine defect. The credibility of the refusal depends on the class believing you would say so if the evidence went the other way.
