IGF-1 LR3 by Dragon Pharma
What Is IGF-1 LR3?
IGF-1 LR3 from Dragon Pharma is a long-acting analogue of insulin-like growth factor 1, a peptide that sits downstream of growth hormone and is best known for its role in tissue repair and cellular growth signaling. The LR3 version has a modified sequence that binds weakly to IGF binding proteins, which extends its active window far beyond that of native IGF-1. Each vial holds 1 mg of lyophilized peptide for reconstitution.
Researchers and athletes who buy IGF-1 LR3 are focused on recovery quality, muscle fullness, and the long game of body composition rather than on a single pre-workout kick. Because it acts on the same receptors as insulin, its effects on nutrient uptake, glycogen storage, and protein synthesis are what make it a staple of more advanced recovery protocols.
Dragon Pharma IGF-1 LR3 1 mg is measured in micrograms and run in 4-8 week research blocks. Timing relative to training and meals matters here more than with GH secretagogues, since IGF-1 works on sugar handling and cellular uptake directly.
IGF-1 LR3 Research Use
IGF-1 LR3 protocols are built around its long half-life, which means a single daily injection is enough at research doses. Most references sit in the 50-100 mcg range per day, with timing chosen around training and carbohydrate intake.
| Parameter | Reference value | Note |
|---|---|---|
| Reconstitution | 1 ml bacteriostatic water per 1 mg vial | Gives a simple 1000 mcg per ml scale |
| Dose | 50-100 mcg per day | Start lower on a first research run |
| Timing | Once daily, post-workout or AM fasted | Keep meal timing consistent |
| Research window | 4-8 weeks with a break after | Rest receptors between blocks |
Practical Notes
Because IGF-1 LR3 can increase the body's sensitivity to insulin, low blood sugar is a real consideration. References advise having carbohydrates available after dosing and never combining high IGF-1 doses with heavy insulin use. Split into two daily doses only when the total daily amount is on the higher end.
IGF-1 LR3 Stacks
IGF-1 LR3 works well as the tissue-level layer under a GH or secretagogue protocol, and pairs naturally with peptides that support the axis above it. Partners below are all Dragon Pharma products.
| Stack partner | Role in the stack |
|---|---|
| CJC-1295 Dac 5mg | Sustained GH environment feeding the IGF axis |
| GHRP-2 | GH pulse support for combined recovery signaling |
| Hexarelin 5 mg | Stronger pulses for advanced tissue-repair phases |
| Ipamorelin/Tesamorelin 10mg | Clean GH support with a body-composition angle |
| Klow Blend | Connective tissue and cellular repair in parallel |
| MOTS-c | Mitochondrial efficiency and endurance adaptation |
When a GH secretagogue is already in the protocol, IGF-1 LR3 is often added in the second half of the block, once the GH environment is established.
IGF-1 LR3 Side Effects
IGF-1 LR3 is well tolerated at research doses, but its insulin-like activity is the reason for the main cautions. Effects are dose-dependent and most manageable with consistent meal timing.
- Hypoglycemia: light-headedness, fatigue, or shaking if dosed without food around it.
- Water retention: mild fullness and water gain are reported at higher doses.
- Joint aches: some users notice achiness when the dose is pushed, which usually resolves when it is lowered.
- Injection site: use sterile technique, rotate sites, and never reuse a syringe.

What is IGF-1 LR3?
IGF-1 LR3 is a long-acting analogue of insulin-like growth factor 1, a peptide involved in tissue repair and cellular growth signaling. Dragon Pharma supplies it as a 1 mg lyophilized vial.
Does IGF-1 LR3 work for muscle growth?
In research contexts it is used for its anabolic signaling, muscle fullness, and recovery effects rather than as a direct steroid-like mass builder. Results build over a block of weeks and depend on training and nutrition.
How much IGF-1 LR3 should I take?
Reference protocols most often sit in the 50-100 mcg per day range, with some conservative protocols starting around 20-40 mcg. A first research run starts low and adjusts based on tolerance.
When should I take IGF-1 LR3?
The most common timing is once daily, post-workout or fasted in the morning, with carbohydrates available afterward. Its long half life means a single daily injection is enough at research doses.
How fast do you see IGF-1 LR3 results?
Early effects such as fullness and faster recovery can appear within the first days, while measurable changes in body composition are typically judged over 4-8 week research windows rather than days.
Can IGF-1 LR3 cause low blood sugar?
Yes, because it acts through insulin-related pathways. Dosing with food available and avoiding combination with insulin reduces the risk of hypoglycemia.
What is the difference between IGF-1 LR3 and IGF-1 DES?
LR3 has a long active window and is dosed once daily systemically, while DES is very short acting and is often referenced for local, site-specific research use. LR3 suits longer recovery-oriented protocols.
How long does IGF-1 LR3 stay potent after reconstitution?
Once mixed, peptides gradually lose potency, and many references advise finishing a reconstituted vial within about 30 days. Store it refrigerated and handle it with sterile syringes.
Does IGF-1 LR3 suppress natural hormones?
No. Unlike anabolic steroids, it does not suppress the natural testosterone axis, which is why it is grouped with non-suppressive recovery peptides rather than with androgens.
Where to buy IGF-1 LR3 online?
Dragon Pharma IGF-1 LR3 is available in this shop as a 1 mg lyophilized vial for research use, with international and domestic shipping.
