The only thing bad IMO about injecting GRF1-29/GHRP-2, is that you need to do it about 3 times a day each which equates to 42 EXTRA pins a week. Plus, spacing them throughout the day (depends on your work schedule) and doing it in fasted state and timing meals after that.
With MK-677 and CJC-1295 with DAC, you are talking about maybe 2-3 extra pins per week and can be done pre-bedtime. Although, GH pulses fade in amplitude over time, IGF-1 levels continue to increase.
Depends on how dedicated you are to staying on a strict schedule and what are your ultimate goals.
