This is module 8 of the NeoPeptidos Professional Certification in Peptide Science. It has 4 lessons; each one can be read on its own and all of them are part of the syllabus assessed at the end of the module.
Lesson 1. Routes of administration and bioavailability
The route of administration determines what fraction of the peptide reaches its target intact. Each route has its own pharmacokinetic logic.
Read the lesson →Lesson 2. The lyophilized form and its diluents
Most peptides come lyophilized (dehydrated by vacuum sublimation) because the dry solid state maximizes their stability. Lyophilization may include cryoprotective excipients (such as mannitol) that give body to the cake and protect the molecule during the process.

For the specialist, knowing subcutaneous technique is part of professional competence. Key elements, presented as technical fundamentals:
Read the lesson →Lesson 4. Non-injectable routes: intranasal, oral and topical
The subcutaneous route dominates for a reason: it delivers the molecule intact. But there are compounds whose literature was built on other routes, and each one has its own rules.
