I only used them with CJC. But ghrp6 makes you hungrier, ghrp-2 is similar but less hunger, and I can't remember the others. Think I used ipamorelin too but it's been a long time.
I ran them when they were more affordable, so they were a viable alternative to GH. These days I think a guy is better off just saving up for like three kits because you'll get way more out of low dose GH than the ghrp peptides. Of course I never tried them without the CJC no DAC, so I can't compare to without. The effects are very subtle, other than the hunger/nausea side effects
