The molecular weight of GHK-Cu sits between 340 and 404 g/mol depending on the salt form, making it a small molecule that distributes efficiently through tissue after injection
Sermorelin is commonly injected before bedtime at doses ranging from 200 to 500 mcg per day, aligning with the body's natural growth hormone (GH) release cycle
Human clinical-trial data (Phase 1/2 studies in wound healing, cardiac injury, and dry eye) exist only for a different, full-length recombinant thymosin beta-4 product, not for the short synthetic fragment marketed as TB-500, so no completed published human trial has evaluated TB-500 specifically for muscle, tendon, or joint recovery
These help protect the molecule as it passes through the digestive system
For women and men over age 18, the adequate intake (AI) is set at 4.0 g/day
