IGF-1 LR3 1.4mg Pen by Spectrum Pharma

IGF-1 LR3 1.4mg Pen by Spectrum Pharma – Potent Anabolic Peptide for Muscle Growth, Recovery & Performance

Overview

IGF-1 LR3 1.4mg Pen by Spectrum Pharma is a pharmaceutical-grade peptide formulation designed to support muscle growth, recovery enhancement, nutrient partitioning, and anabolic signaling. IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a long-acting variant of IGF-1 with extended half-life, making it highly effective at stimulating protein synthesis and muscle cell growth.

Delivered in a pre-filled pen format, this product provides predictable dosing, convenience, and consistent performance for athletes and bodybuilders seeking advanced muscle-building results.

How IGF-1 LR3 Works

IGF-1 LR3 binds to IGF receptors in muscle tissue, activating pathways that:

• Increase protein synthesis

• Enhance amino acid uptake

• Stimulate muscle cell growth and hypertrophy

• Improve recovery from intense training

• Enhance glucose and nutrient partitioning

The long-acting modification (LR3) results in sustained activity, supporting prolonged anabolic signaling throughout the day.

Key Benefits

• Promotes lean muscle growth and hypertrophy

• Improves recovery between workouts

• Enhances nutrient efficiency and muscle fullness

• Supports training intensity and adaptation

• Extends anabolic effects due to LR3 modification

IGF-1 LR3 is especially effective for advanced physique goals and intense training phases.

Best Stack Combinations

IGF-1 LR3 1.4mg Pen is commonly stacked with:

Growth & Recovery Stacks

• HGH or Sermorelin / CJC-1295 & Ipamorelin – amplified GH support

• Peg-MGF or MGF – targeted tissue repair and growth

• BPC-157 or TB-500 – recovery and injury support

• Testosterone base (Enanthate / Cypionate / Propionate) – foundational anabolic support

Conditioning / Cutting Stacks

• Cut Mix or Recomp Mix – lean mass preservation

• AOD-9604 or T3 – metabolic support for fat loss

Proper stack design helps maximize lean gains and recovery while minimizing unwanted side effects.

Suggested Cycle & Usage

Typical Dosing Protocol

• Cycle length: 6–10 weeks

• Typical dosage: 20–50 mcg per day

• Administration: Subcutaneous injection

• Timing: Post-workout or before sleep for optimal responsiveness

Because IGF-1 LR3 has a long duration of action, consistent daily dosing ensures sustained anabolic signaling.

Potential Side Effects

When used responsibly and at recommended doses, IGF-1 LR3 is generally well tolerated. Possible mild side effects may include:

• Temporary injection-site irritation

• Mild water retention

• Low blood-sugar symptoms (hypoglycemia)

• Headache or dizziness in sensitive individuals

• Occasional mild fatigue

Maintaining proper nutrition (especially carbohydrates) around dosing can help mitigate hypoglycemic symptoms.

Post Cycle Considerations

IGF-1 LR3 does not typically suppress natural hormone production, and traditional post-cycle therapy (PCT) is not always required when used alone. However, if stacked with suppressive anabolic steroids, a full PCT protocol (including SERMs like Nolvadex or Clomid) may be recommended.

Maintaining nutrient intake, sleep quality, and recovery routines ensures the best long-term results.
