About GHRP-2

GHRP-2 is a synthetic hexapeptide GH secretagogue that stimulates the pituitary gland's ghrelin receptor (GHSR-1a) to trigger a growth hormone pulse. It produces less hunger than GHRP-6, making it versatile for both cutting and lean-bulking phases. Unlike Ipamorelin, GHRP-2 can elevate cortisol and prolactin at higher doses, which is worth monitoring in your logs.

Because GHRP-2 has a half-life of approximately 30 minutes, three injections per day are standard practice to sustain meaningful IGF-1 elevation. Stacking with CJC-1295 (no DAC) amplifies each GH pulse significantly through complementary GHRH receptor activation.

Inject SQ (subcutaneous), fasted or 2+ hours post-meal. Log each injection time in Shotlee to maintain protocol consistency.

Injection Timing Guide

๐ŸŒ…

Morning

Fasted, before breakfast. Wait 30+ minutes to eat after injecting to preserve the GH pulse. Best timed shortly after waking.

๐Ÿ’ช

Post-Workout / Mid-Day

Post-workout on training days for enhanced recovery signaling. On rest days, inject 2โ€“3 hours after your last meal. Avoid injecting immediately after eating.

๐ŸŒ™

Pre-Sleep

30โ€“60 minutes before bed on an empty stomach. Amplifies the natural nocturnal GH pulse during deep sleep โ€” widely regarded as the most impactful injection of the day.

What to Track with GHRP-2

๐Ÿ’‰ 3x Daily Dose Log

Record exact mcg per injection and injection site (abdomen, thigh). Consistency in dosing is key to reliable IGF-1 elevation. Shotlee timestamps each entry automatically.

โฐ Injection Timing

Log fasted status and time of each injection. Meals blunt the GH pulse โ€” tracking the gap between food and injection reveals protocol compliance issues.

๐Ÿ”ฌ IGF-1 Labs

Enter quarterly IGF-1 blood test results to confirm the protocol is working. GHRP-2 typically raises IGF-1 by 20โ€“50% from baseline. Shotlee graphs trends over time.

๐Ÿ“Š Stack Log (CJC-1295)

If combining with CJC-1295, log both peptides together per injection. Stacking significantly amplifies the GH pulse โ€” track both to understand the full picture.

๐Ÿ˜ด Sleep Quality

Rate sleep quality after the pre-sleep injection. GH pulse quality during the night directly influences recovery, body composition, and mood โ€” a key proxy for protocol effectiveness.

โš ๏ธ Cortisol Symptom Flag

At 300mcg+ per injection, GHRP-2 can elevate cortisol. Note any anxiety, difficulty sleeping, or elevated morning resting heart rate โ€” early signals to adjust dose.

FAQ

Why does GHRP-2 require 3 injections per day?

GHRP-2 has a short half-life of approximately 30 minutes. A single injection triggers a GH pulse that decays quickly. Three daily injections โ€” morning, mid-day, and pre-sleep โ€” are needed to sustain elevated IGF-1 and meaningful GH effects throughout the day. Shotlee makes logging all three injections simple with time-stamped entries.

Can I track GHRP-2 stacked with CJC-1295 in Shotlee?

Yes. Shotlee supports logging multiple peptides per injection session. You can record your GHRP-2 dose and CJC-1295 dose together, track the timing, and review your full stack history over weeks and months.

What should I track when using GHRP-2?

Key metrics to track include: dose per injection (mcg), injection time and fasted status, sleep quality and energy levels as GH pulse indicators, IGF-1 lab values (quarterly), any cortisol-related symptoms at higher doses, and hunger level if you are comparing to GHRP-6.
