How to Use IGF-1 DES
Complete guide to IGF-1 DES dosing, administration, timing, and protocol recommendations.
Quick Overview
IGF-1 DES is insulin-like growth factor 1 with its first three amino acids chopped off, leaving a 67-residue peptide. That small cut makes it bind poorly to the IGF binding proteins that normally keep IGF-1 in check, so more of it reaches the receptor and it acts stronger, but shorter. It occurs naturally in small amounts (it was first isolated from human fetal brain tissue) and is sold online as a muscle-building research peptide. There are no human trials of it at all, so everything said about it in people is extrapolation.
Dosing Guidelines
Common Dose
Community-reported 20-100 mcg per day
Frequency
Usually once daily on training days
Dose Range
20-100 mcg (community reports, no clinical data)
Note: No human trial has ever tested this peptide, so there is no validated dose. Community numbers are extrapolated from anecdote. It is more potent per microgram than IGF-1, and hypoglycemia is the main acute risk; people who use it typically eat carbohydrates around injections. Anyone with a history of cancer should not be experimenting with IGF-1 analogues.
Administration Method
Intramuscular or subcutaneous injection (community practice); studied by injection in animals only
Best Time to Take
Around training, per community practice
Its short action and weak binding-protein attachment mean any effect is brief and local, which is why users inject it near training into the worked muscle. There is no human data on timing. Taking it fasted raises the hypoglycemia risk.
Protocol Duration
Community reports describe short cycles of about 4-6 weeks; there is no human data on safe duration
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •Low blood sugar (hypoglycemia), the most commonly reported problem
- •Dizziness or lightheadedness
- •Injection site pain or swelling
- •Water retention
- •Theoretical: growth of existing tumours (IGF-1 signalling drives some cancers)
