Description
IGF-1LR3 1 mg Bio-Peptide — This Bio-Peptide formulation delivers a modified version of IGF-1 with an extended half-life that directly stimulates muscle cell growth (hyperplasia) and differentiation. Unlike HGH which works indirectly through IGF-1, IGF-1 LR3 provides direct anabolic signaling to muscle tissue, promoting both hypertrophy (cell growth) and hyperplasia (new cell creation). This formulation is dosed at 1 mg per unit.
Key Benefits
- Long-R3 IGF-1 analogue — extended half-life via Arg3 substitution
- Direct IGF-1 receptor activation for satellite-cell recruitment
- Bypass hepatic IGF-1 production for targeted muscle effect
- Subcutaneous or site-injection protocols
- Stacks with GH-axis compounds (HGH, CJC-1295) for synergy
- Each unit dosed at 1 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 40–60 mcg/day SubQ, split pre-workout and post-workout for training-day protocols. Cycles 4–6 weeks on / 2–4 weeks off to avoid receptor downregulation. Site-inject into target muscles for localised hypertrophy signals.
How It Works
IGF-1 with an Arg→Glu substitution at position 3 plus 13-amino-acid N-terminal extension. The modification reduces IGF-binding-protein affinity, dramatically extending free-IGF-1 exposure in plasma. Binds IGF-1R directly, triggering PI3K/Akt/mTOR anabolic signalling.
Pharmacokinetics
Plasma half-life approximately 20–30 hours — vs native IGF-1’s 10 minutes. Daily SubQ dosing adequate. Reconstituted vial stable in fridge 4–6 weeks. Freeze stock vial for longer storage.
Potential Side Effects
Hypoglycaemia during injection window — eat carbs within 30 minutes. Joint pain on long cycles (carpal tunnel-like). Receptor downregulation with continuous use — cycle on/off matters. Potential cancer-promotion signal on long runs — time-limited use.
Cycle & Stacking Guide
4-week cycles at 40–60 mcg/day pre/post workout. Pair with HGH for axis-level synergy or standalone for muscle-specific effect. Keep carbohydrate-rich snack at hand for hypoglycaemia.
Manufacturer Notes
Bio-Peptide produces research peptides with published HPLC purity data. Lyophilised powder in amber-glass vials; reconstitute with bacteriostatic water before use.
Storage & Handling
Store at recommended temperature (15–25°C; peptides and HGH at 2–8°C after reconstitution). Protect from light and moisture. Keep out of reach of children. For research and educational purposes only.
