- Injectable (subcutaneous):
- Bioavailability: Higher (~80-90%)
- Standard in Russian research
- More predictable dosing
- Requires injection skills
- Best for serious use
- Oral/sublingual:
- Bioavailability: Lower (~30-50% estimated)
- Some Russian formulations available as tablets
- More convenient (no needles)
- May require higher doses (20mg oral vs 10mg injection)
- Less studied effectiveness

- Reconstitution for injectable:
- Cartalax typically 20mg vial
- Add 2ml bacteriostatic water = 10mg/ml
- 10mg dose = 1ml (100 units on insulin syringe)
- One 20mg vial = 2 days
- Need 5 × 20mg vials per 10-day cycle
- Storage:
- Before reconstitution: Freeze or refrigerate
- After reconstitution: Refrigerate 2-8°C always
- Shelf life: 28-30 days reconstituted
- Standard peptide storage practices
