Written by Michael Carroll — Owner, Director of Research · Reviewed by the Peptide Initiative Research Team · Editorial standards
Dosing
How much do I take?
Subcutaneous injection: A small injection into the fatty layer just under the skin — the same way insulin is given.
Bioavailability High — most of the dose reaches your bloodstream, just more gradually than an IV.
50 mg
Frequency
Three times weekly
Duration
6 weeks to 48 weeks depending on indication
Dose used in controlled clinical trials, e.g. 50 mg SC three times weekly in HIV and atopic dermatitis studies [5].
Timing
Best time to take
Morning injection for consistency
With food?
Can be taken with or without food; no food interactions
If stacking
Can be combined with other immune-supporting supplements; allow 2 hours between other injections
Adjusting your dose
Increase if
- Well-tolerated after 2 weeks
- Minimal side effects observed
- Seeking enhanced immune response
Decrease if
- Experiencing persistent local reactions
- Fever develops
- Unusual fatigue occurs
Signs of right dose
- Improved energy levels after 1-2 weeks
- Better recovery from exercise
- Enhanced overall well-being
- Improved wound healing
