Peptide entry
IGF-1 LR3
Evidence / context
Evidence: Limited. Hypertrophy and nutrient-partitioning support are reported use cases.
Available vial formats
- Conservative 20 mcg per injection post-workout on training days (6 units per injection)
- Standard 40 mcg per injection post-workout on training days (12 units per injection)
- Aggressive 50-60 mcg per injection post-workout on training days (15-18 units per injection) short cycle only if clearly tolerated
- Cycle length 4-6 weeks, then 6+ weeks off
- Best timing Post-workout with food/carbohydrates available.
Reconstitution
Reconstitution:
1. Swab vial tops with alcohol.
2. Add 3.0 mL bacteriostatic water slowly.
3. Swirl gently - do not shake.
4. Refrigerate 2-8 C.
Concentration:
1 mg / 3.0 mL = 333 mcg/mL
U-100 conversion:
20 mcg = 6 units per injection
40 mcg = 12 units per injection
50 mcg = 15 units per injection
60 mcg = 18 units per injection
