IGF-1 LR3

long-r3 igflr3

Extended-half-life IGF-1 analog. Hypoglycemia warning — careful protocol design + measurement required.

Half-life
1.0 d
Out of system
~5 days
Route
Subcutaneous
Level
Advanced

Daily dosing holds steady levels. After the last dose, roughly 97% has cleared in ~5 days (five half-lives) — the window that matters for washouts, bloodwork and surgery.

What IGF-1 LR3 is used for

  • Long-acting IGF-1 analog — measurable muscle/recovery effect in trained users
  • Used in bodybuilding contexts for site-specific growth
  • Tracks well with bloodwork (IGF-1 panel)

How it's typically used

Research range: 20–80 mcg subcutaneous post-workout. Track BG closely.

What to watch for

  • Hypoglycemia is acute — eat carbs around injection
  • Theoretical cancer-growth concerns
  • Advanced compound — sourcing and dosing precision matter

About Performance & GH

What they are
Growth-hormone secretagogues and related performance compounds. Rather than supplying GH, they push your pituitary to release more of its own in a pulse.
How they're run
Subcutaneous injection, most often at night on an empty stomach so the pulse lands with natural sleep-driven GH release.
What to watch
Water retention, tingling hands, and hunger swings are the common early signs. Raising GH raises IGF-1 — worth tracking on bloodwork, and a reason to avoid these with any cancer history.
