Research chemical vendors can't legally label products with the real name, so IGF-1 LR3 often appears under coded SKUs. If you're shopping and see any of these, it's the same compound:
- LR3
- IGF LR3
- Long R3 IGF
Codes shown are for identification only. Always verify third-party COAs before purchase.

Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
