IGF-1 & MGF analogues
Street names: IGF-1 LR3, Somedin, PEG MGF, DES IGF
Overdose? Act now. Call emergency services — say "unresponsive, not breathing". Give naloxone for opioid-like signs. Hotlines
⚡What it does
- Potent muscle-growth signaling (LR3 lasts ~20–30 h in the body)
- MGF variants marketed for repair
⚠Key risks
- Hypoglycemia — IGF-1 pulls blood sugar down hard; dangerous in diabetics
- Theoretical but serious cancer concerns — IGF-1 feeds tumor growth
- Site-growth claims (localized muscle) are anecdotal
- Microgram dosing errors are easy and consequential
✚Overdose signs
- Low blood sugar: shaking, sweating, confusion — eat sugar, seek help
- Injection-site infection

Category comparison — Peptides & Research Chemicals
| Substance | Class | Top risks | Street price |
|---|---|---|---|
| IGF-1 & MGF analogues | Unscheduled — 'research chemicals'; IGF-1 is Rx | Hypoglycemia — IGF-1 pulls blood sugar down hard; dangerous in diabetics; Theoretical but serious cancer concerns — IGF-1 feeds tumor growth | ~$30–$80 per vial grey-market |
| GHRPs & GH Secretagogues | Unscheduled — 'research chemicals' | All are 'research chemical' grade unless pharmacy-sourced: purity unknown; Water retention, carpal-tunnel symptoms, insulin resistance with chronic use | ~$15–$40 per vial grey-market |
| Somatropin (Human Growth Hormone) | Rx-only; Schedule III/IV equivalent in most regions | Counterfeit rate near total — independent tests find most 'HGH' is hCG, IGF, or nothing; Real GH at abuse doses: insulin resistance, carpal tunnel, organ growth (acromegaly features) | ~$2–$10 per IU grey-market |
