IGF-1 LR3 (Long Arginine 3-IGF-1) is a modified form of insulin-like growth factor 1 with an extended half-life due to reduced binding protein affinity.
20-50 mcg per day, often administered bilaterally into target muscles.
Potent hypoglycemia risk — always have glucose available. May promote tumor growth. Organ enlargement possible with extended use. Very potent — careful dosing required. Not FDA-approved.
IGF-1 LR3 binds IGF-1 receptors with high affinity but has reduced binding to IGF-binding proteins, keeping it active in circulation longer. It promotes both muscle hypertrophy (larger cells) and hyperplasia (more cells).

From a research standpoint, this combination of neuro-support and metabolic agents is well thought out. The melatonin-GABA synergy offers promising effects in sleep cycle modulation and nervous system stability. The inclusion of L-Arginine and Glutamine adds a regenerative and circulatory dimension that broadens potential applications in recovery and immune response studies. Packaging was professional, and everything arrived in perfect condition. Excellent quality for lab-based exploration and study models
Exceptional formulation. From a research perspective, the synergy between L-Carnitine, ATP, and AMP is impressive. The compound is well-structured to support cellular energy metabolism and physical endurance under lab conditions. Noticed enhanced adaptation and recovery indicators in performance simulation studies. Definitely a high-quality product for scientific applications — clean, well-packaged, and delivered quickly. Perfect for serious research scenarios.
Shredded AF 300 is hands down one of the most effective fat burners I’ve tried. Within 20 minutes, I feel a clean, powerful energy surge and razor-sharp focus. It suppresses appetite without making me jittery, and the thermogenic effect is real — I sweat more during workouts and feel like I’m burning fat all day. No crash, no brain fog. Perfect for cutting phases or morning cardio sessions. Definitely a staple in my supplement stack
I’ve used many peptides, but IGF-1 DES 5 mg stands out. The localized muscle pumps are unreal — you can actually feel and see the difference post-injection. Recovery has improved dramatically, and I’ve gained noticeable lean mass in just a couple of weeks. Strength is up, endurance is up, and I feel more 'on' during every workout. It’s fast-acting and perfect to stack with other growth-related peptides. Highly recommend for serious lifters.
"I’ve struggled with sleep for years — falling asleep was hard, and staying asleep was even harder. DSIP 5 mg has truly changed the game for me. Within 30 minutes of dosing, I feel naturally drowsy without any grogginess or forced sedation. My sleep is deeper, and I wake up feeling genuinely rested and alert. No morning fog, no dependency. If you're dealing with insomnia or poor sleep quality, this is absolutely worth trying.
