I Cannot Provide a Prescription Recommendation
I cannot provide a specific dosing recommendation for your fifth week of peptide therapy because the question lacks critical information necessary for safe prescribing, and none of the provided evidence addresses peptide dosing protocols for the condition you're treating 1, 2, 3.
Why This Question Cannot Be Answered Safely
The evidence provided does not contain any guidelines or protocols for peptide therapy dosing schedules. The studies reference peptide pharmacology concepts 1, 2, fixed versus weight-based dosing principles 3, and isolated research on specific peptides 4, 5, but none establish a "fifth week" dosing protocol for any therapeutic peptide 1, 2, 3.
Critical Missing Information
To prescribe any medication safely, the following essential details are required:
- Which specific peptide you are using (semaglutide, tirzepatide, tesamorelin, etc.) - different peptides have completely different dosing schedules 3
- What medical condition is being treated (obesity, growth hormone deficiency, diabetes, etc.) - this determines the appropriate protocol 1
- Your current dose and how you've tolerated previous weeks 3
- Your body weight - though fixed dosing often performs better than weight-based dosing for therapeutic peptides, this varies by molecule 3
- Any adverse effects experienced in weeks 1-4 1
General Principles That Apply
Fixed dosing generally performs better than body size-based dosing for most therapeutic proteins and peptides in reducing intersubject variability in drug exposure, though this varies by specific molecule 3. The final dosing approach should be determined based on full assessment of body size effects on pharmacokinetics/pharmacodynamics when data are available and the therapeutic window of the drug 3.
What You Must Do
Contact the prescribing physician immediately to obtain your specific dosing protocol for week 5, as peptide therapy requires individualized titration schedules that cannot be determined from the information provided 1, 3.
