The principal use of Mod GRF 1-29 is to provide increased GH levels, which also results in increased IGF-1levels. An increase in these levels can aid fat loss and in some instances can aid muscle gain as well. Generally, Mod GRF 1-29 is used as part of alternate plan to using GH, and only rarely is combined with GH.

The other principal GHRH product is CJC-1295. In almost all instances I recommend Mod GRF 1-29 over CJC-1295. The products differ in their duration of action. Mod GRF 1-29 has an approximately-ideal short duration of action allowing pulsatile dosing, whereas CJC-1295 has an extended duration of action preventing such dosing.

In some instances, Mod GRF 1-29 is marketed as “CJC-1295 w/o DAC.

Combine Mod GRF 1-29 with a GHRP

Mod GRF 1-29 best shows its value when taken at the same time as a GHRP product, rather than used alone. For any given amount of added GH production, less of a GHRP is needed when the GHRP is stacked with Mod GRF. Or if using the same amount of a GHRP, a greater increase in GH production may be produced.

Example usages are 100 mcg of Mod GRF 1-29 taken at the same time as 100 mcg of GHRP-6 or ipamorelin. Such dosings will provide at least as much GH release as for example 300 mcg of either of these GHRP products taken alone.
The combination of Mod GRF 1-29 and a GHRP is synergistic. The GHRP stimulates a pulse of GH release, and the Mod GRF amplifies it.
