IGF-1 DES

50–150 mcg around training

Truncated 67-amino-acid variant of IGF-1 from 1990s research, missing its first three amino acids, giving it about ten times the anabolic potency of regular IGF-1 with a short 20–30 minute half-life. Studied in animals for muscle growth, recovery, and tissue repair; remains an unapproved research chemical.

Important: IGF-1 peptides are insulin-like and can drop your blood sugar. Always eat a meal with protein and carbs shortly after injecting, and watch for low blood sugar signs (shakiness, sweating, dizziness). Do not dose right before bed.

IGF peptides are often reconstituted with bac water for short-term use. Some prefer a low-pH diluent for longer storage, but bac water is the common practical choice for a vial used within its window.

  1. Use bacteriostatic water as the diluent.
  2. Add the water slowly, letting it run down the inside wall of the vial rather than onto the powder.
  3. Swirl gently to mix, then leave it to dissolve. Do not shake.
  4. Give it a few minutes. The finished solution should be clear and colourless.

Protocol

Route: Subcutaneous or intramuscular

Standard protocol (subcutaneous or intramuscular)

  • 0.05 mg to 0.15 mg (50 to 150 mcg) per day, used pre- or post-workout
  • It is short-acting, so it is timed right around training, often injected into the trained muscle and split between left and right sides

Dosing detail

  • Common dose is 0.05 mg to 0.15 mg (50 to 150 mcg) per day, around training.
  • Short half-life, so it acts locally and is cleared quickly. Inject into or near the worked muscle.
  • Always eat after dosing because of the blood-sugar drop. Do not inject close to bedtime.
  • Small draws, so a smaller fill keeps the numbers easy.

Duration

  • Keep cycles under 4 weeks (30 days max) with at least 2 weeks off, to keep IGF receptors responsive. Eat shortly after every dose.

Notes

  • A fast, short-acting IGF-1 variant with a local action.
  • Watch for low blood sugar signs given its insulin-like action.
  • Inject subcutaneously and rotate sites.

Storage and handling

  • Keep the powdered (lyophilized) vial in a cool, dark place. Refrigerate it for longer-term storage before mixing.
  • Once reconstituted and refrigerated at 2–8 °C away from light, use the vial within 90 days.
  • Do not freeze a reconstituted vial, and keep it away from heat and sunlight.
  • If the solution turns cloudy, develops floating particles, or shows any other sign of degradation, stop using that vial.
