Comparison
Creatine Monohydrate vs GHRP-2
Side-by-side of Creatine Monohydrate and GHRP-2. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Creatine Monohydrate
Creatine monohydrate supplement guide: 3-5 g/day raises phosphocreatine stores, lifts anaerobic output 5-15%, supports lean mass and cognition under sleep loss.
GHRP-2
GHRP-2 peptide (pralmorelin, KP-102) is a synthetic hexapeptide ghrelin-receptor agonist that triggers pulsatile growth hormone release via the pituitary.
Effects at a glance
Creatine Monohydrate
- •Increases anaerobic strength and power output by ~5 to 15% across multiple training studies
- •Adds ~1 to 2 kg of lean body mass over 4 to 12 weeks, partly intracellular water and partly true tissue gain
- •Improves 1-rep max on bench and squat by ~5 to 10% versus placebo in resistance-trained adults
- •Cognitive benefit appears mainly under sleep deprivation or high mental load, less so in well-rested individuals
- •Saturation reached in ~28 days at 3 to 5 g/day, or ~5 to 7 days with a 20 g/day loading phase
- •No evidence of renal harm in healthy adults across long-term studies; caution in pre-existing severe renal disease
GHRP-2
- •Hexapeptide ghrelin-receptor agonist that stimulates pulsatile GH release within 15 to 30 minutes
- •Strongest appetite signal among GHRPs at standard doses; centrally mediated via NPY/AgRP
- •Produces measurable cortisol and prolactin rise (more than ipamorelin, less than GHRP-6)
- •Approved in Japan as pralmorelin for GH-deficiency diagnostic provocation; not FDA approved
- •Anecdotal protocols use 100 to 300 mcg subcutaneously 2 to 3 times daily on an empty stomach
- •Banned by WADA under S2; detection methods validated in accredited labs

Safety profile
Creatine Monohydrate
Common side effects
- water retention
- mild GI upset at loading doses
- weight gain (2 to 4 lb from intracellular water)
Contraindications
- severe renal impairment
Interactions
- caffeine (high-dose acute): mixed data on ergogenic interference; chronic use appears compatible(minor)
- nephrotoxic drugs (NSAIDs, cyclosporine): theoretical additive renal strain in at-risk patients(moderate)
GHRP-2
Common side effects
- acute hunger
- head pressure or flushing
- water retention
- vivid dreams
- tingling at injection site
- transient lethargy
Contraindications
- pregnancy
- active malignancy
- history of pituitary tumor
- uncontrolled diabetes
- severe insulin resistance
Interactions
- CJC-1295: synergistic GH release; commonly co-administered for larger pulse(minor)
- sermorelin: additive GH release via parallel GHRH and ghrelin pathways(minor)
- insulin: sustained GH can blunt insulin sensitivity over weeks(moderate)
- corticosteroids: blunt GH response and amplify cortisol load(moderate)
Which Should You Take?
Creatine Monohydrate comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-A outcome catalogued. GHRP-2 is the right call when one of the conditionals below applies.
- → If your priority is strength or hypertrophy, pick Creatine Monohydrate.
- → If your priority is focus or working memory, pick Creatine Monohydrate.
- → If your priority is growth-hormone axis, pick GHRP-2.
- → If your priority is appetite regulation, pick GHRP-2.
Edge case: If you want to avoid research-only / gray-market sourcing, Creatine Monohydrate is the more accessible choice.
Default choice: Creatine Monohydrate. Lower friction to source, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for GHRP-2 only if your priority sits squarely in the goals it owns above.

Common questions
What is the difference between Creatine Monohydrate and GHRP-2?
Creatine Monohydrate and GHRP-2 differ in category (supplement vs peptide), mechanism, and typical dosing. See the side-by-side table for full details.
Which has a longer half-life, Creatine Monohydrate or GHRP-2?
Creatine Monohydrate half-life is 3 hours; GHRP-2 half-life is 0.5 hours.
Can you stack Creatine Monohydrate with GHRP-2?
Stack compatibility depends on mechanism overlap, legal status, and individual response. Check each compound page for specific interactions and contraindications before combining.
