CJC-1295 No-DAC vs IGF-1 DES

CJC-1295 No-DAC vs IGF-1 DES — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

CJC-1295 No-DAC
Growth Hormone & IGF

CJC-1295 No-DAC (also called Modified GRF 1-29 or Mod GRF) is a short-acting GHRH (Growth Hormone-Releasing Hormone) analog consisting of the first 29 amino acids of endogenous GHRH with four amino acid substitutions to improve stability and receptor binding....

IGF-1 DES
Growth Hormone & IGF

IGF-1 DES (des(1-3)IGF-1) is a naturally occurring truncated form of IGF-1, produced endogenously in the brain and other tissues, that lacks the first three N-terminal amino acids (Gly-Pro-Glu) of full-length IGF-1. This truncation eliminates its binding to IGF-binding proteins (...
