CJC-1295 DAC

GHRH is a growth hormone releasing factor peptide that is comprised of either 44 or 40 amino acids and is abbreviated as GRF(1-29). The biologically active portion resides in the first 29 amino acids so the synthetic forms of GHRH are made up of just these 29 amino acids.

CJC-1295 has an added amino acid lysine which links to a drug affinity complex (DAC). CJC 1295 without DAC is modified GHRH or GRF(1-29).

Modified GRF(1-29) is a short-estered GHRH, while CJC-1295 is a long-estered GHRH. Effectively, the long-estered GHRH can be run once a week if you can find the real deal.
Since maufacturing CJC 1295 is a complex and costly process, most all CJC 1295 being currently sold is really GRF(1-29). This analysis confirmed this assumption!!

Its very profitable to buy GRF as middleman and sell them as CJC 1295-DAC
