01The basics

What IGF-1 LR3 1mg is

IGF-1 LR3 (Long R3 IGF-1) is a lab-made version of insulin-like growth factor 1, the hormone that carries out many of growth hormone’s effects. Each vial contains 1 mg of freeze-dried powder for mixing with bacteriostatic water. Two changes to its structure stop it binding the proteins that normally inactivate IGF-1, so it lasts far longer: about 20–30 hours.

It was designed as a reagent for growing cells in labs and has never been tested in people. It acts like insulin as well as a growth factor, so the most immediate danger is low blood sugar. Please read this page before considering it.

02How it works

How it works

  • IGF-1 receptor activation drives cell growth, protein synthesis and the multiplication of muscle stem cells.
  • Insulin-like effects: it pushes glucose into cells, lowering blood sugar.
  • Long-acting: because binding proteins don’t neutralize it, its effects last much longer than natural IGF-1’s.

03Half-life

Half-life, in plain numbers

A half-life of about 20-30 hours means half of what is in the body is gone after that time, then half of the rest, and so on. For an injected peptide it reflects how quickly the body breaks the chain down and clears it.

04Clinical reference

Dosing information

Clinical reference. IGF-1 LR3 has no human dose. The only approved IGF-1 medicine, mecasermin, is used for children with severe IGF-1 deficiency: 0.04–0.12 mg per kg twice a day, always given with a meal because of hypoglycemia risk.

Talk to a doctor before use.

Mixing math. Adding 2 ml of bacteriostatic water (or a dilute acetic acid solution, as some prefer) to the 1 mg vial gives 500 mcg per ml. On a U-100 insulin syringe:

  • 20 mcg = 0.04 ml = 4 units
  • 50 mcg = 0.1 ml = 10 units

05Mixing

Mixing and storage

  • Bacteriostatic water and syringes are sold separately; see Pairs well with below.
  • Add liquid slowly and swirl very gently; it’s fragile.
  • Refrigerate (2–8 °C) once mixed and use it promptly.

06Measure it

Measure it

Type in the amount your prescriber gave you, or the one you are working from, and this turns it into what to draw up or count out from this exact product. It only does the arithmetic; it never suggests an amount.

07Injection sites

Where it is injected

IGF-1 LR3 1mg arrives as a freeze-dried powder. After it is mixed with bacteriostatic water it is normally injected under the skin, into the fat layer, with a short insulin needle.

Common siteMuscle drawing: OpenStax & Tomáš Kebert, umimeto.org, CC BY-SA 4.0, recoloured.
1Belly (abdomen)Fat under the skin of the bellySubQ
Volume per siteAbout 1 ml or lessNeedle4–13 mm insulin needle, 29–31G
  1. Pick a spot at least 5 cm (two finger-widths) from the belly button.
  2. Avoid scars, stretch marks, bruises and the waistband.
  3. Pinch up a fold of skin and inject into the fold.

Why it is used. The most fat to work with, easy to see, and the steadiest absorption. Weekly pen medicines list it first.

Careful. Move each injection at least 2–3 cm from the last to avoid firm fatty lumps (lipohypertrophy).

2Front of thighFat under the skin of the thighSubQ
Volume per siteAbout 1 ml or lessNeedle4–13 mm insulin needle, 29–31G
  1. Sit and look down at the front of your thigh.
  2. Use the middle band: a hand-width below the hip crease and a hand-width above the knee.
  3. Pinch the skin and inject into the fold.

Why it is used. Easy to reach while seated, and a handy second area to rotate with the belly.

Careful. It can absorb a little more slowly than the belly; hard leg training straight afterwards can speed it up.

3Back of upper armFat over the tricepsSubQ
Volume per siteAbout 1 ml or lessNeedle4–13 mm insulin needle, 29–31G
  1. Find the soft, fleshy area at the back of the upper arm.
  2. Stay halfway between the shoulder and the elbow.
  3. Pinch the skin and inject into the fold.

Why it is used. A third area to rotate through, so every spot gets a longer rest.

Careful. Hard to pinch and reach with one hand; most people need a helper.

Route for IGF-1 LR3 1mgUnder the skin (subQ)

  • Start with the bellyIt has the most fat and the steadiest absorption, and you can see what you are doing. The thigh and arm are there to rotate into.
  • Short needle, small volumeAround 1 ml or less per spot. A 4–13 mm insulin needle reaches the fat without touching muscle; pinch up the skin if you are lean.
  • New spot every timeShift 2–3 cm from the last injection. Reusing one spot causes firm lumps that absorb unevenly.
  • Wash your hands
  • Alcohol on the stopper and skin, let it dry
  • New sterile needle and syringe every time
  • Never share any of it
  • Sharps into a puncture-proof container

08Risks

Side effects and risks

There’s no human safety data for IGF-1 LR3. What we know comes from approved IGF-1 medicine and biology.

Low blood sugar

Shakiness, sweating, confusion, fast heartbeat or fainting. Eat carbohydrates right away; severe hypoglycemia is an emergency. Never inject without eating.

Cancer growth

IGF-1 promotes cell growth and survival, and high IGF-1 is linked to some cancers. It could speed the growth of an existing tumour.

Tissue overgrowth

Long-term excess IGF-1 can enlarge organs and tissues, as in acromegaly.

Headache and swelling

Seen with approved IGF-1 treatment.

No human testing

It was made for cell culture. Doses in circulation aren’t based on any trial.

Don’t use it if you

Have diabetes, a history of low blood sugar, cancer or a history of it, are pregnant or breastfeeding, or are under 18.

09Interactions

Interactions

Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.

  • SeriousInsulin and diabetes medicines

    IGF-1 lowers blood sugar by itself; together with insulin or diabetes tablets hypoglycemia is a real risk.

  • Good to knowNo interaction studies

    IGF-1 LR3 is a research peptide and has never been tested against other medicines.

10Safety

Before you use it

  • Know the signs of low blood sugar and keep fast sugar on hand.
  • Have a glucose meter and check after injecting.
  • Never inject on an empty stomach or before driving.
  • Test IGF-1 and fasting glucose before starting.

13Questions

Common questions

IGF-1 LR3 or HGH?

HGH works partly by raising your own IGF-1, within your body’s controls. IGF-1 LR3 skips that step, with stronger and less controlled effects, and no human safety data.

Why is low blood sugar such a risk?

IGF-1 shares receptors and pathways with insulin. A long-acting analogue can lower blood sugar for hours.

Is it banned in sport?

Yes. IGF-1 and its analogues are on the World Anti-Doping Agency’s prohibited list.

How fast is shipping in Canada?

Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.

Is IGF-1 LR3 legal in Canada?

It isn’t approved by Health Canada for human use and isn’t a controlled substance.

How is my order packaged?

In a plain, unbranded box with no product names on the outside.
