- Subcutaneous (abdomen/thigh)
- 85–92%
- 30–60 minutes
- Low. Self-administered with insulin syringe
- Minimal if rotated
- Recommended for longevity protocols. Consistent absorption, low skill barrier
- Intramuscular (deltoid/glute)
- 90–95%
- 15–30 minutes
- Moderate. Deeper injection, larger needle
- Moderate. Higher bruising risk
- Not necessary for Thymalin. SC route achieves therapeutic levels without IM trauma
- Oral (tablet/capsule)
- <5%
- N/A
- None
- Ineffective. Peptide bonds are cleaved by gastric proteases before absorption
- Sublingual (under tongue)
- 10–15%
- 20–40 minutes
- Insufficient. Absorption through oral mucosa is too variable for consistent dosing
