Oral
Oral discussions usually center on convenience and whether a compound can remain stable enough to matter after digestion. Expert Opinion The gap between marketing language and actual bioavailability is often larger than sellers admit.
Injectable
Injectable use raises contamination, sterility, training, and injection-site risk immediately. Expert Opinion It also tends to create the strongest illusion of potency simply because it feels more medical.
Nasal
Nasal formats are discussed less often and tend to carry their own uncertainty around absorption and quality control. Anecdotal
Bottom line
Route decisions should be treated as safety decisions, not just convenience decisions. If no one involved can explain bioavailability limits, sterility expectations, and stop conditions, the discussion is undercooked.
Pair with dosage, safety, and disclaimer.
