Where These Numbers Come From
MK-677 has substantial human clinical data — rare for a non-FDA-approved GH compound.
Murphy et al. (1998) showed 25 mg daily reversed diet-induced catabolism and significantly increased GH and IGF-1 levels (PMID 9467534). The landmark Nass et al. (2008) 2-year study using 25 mg daily demonstrated sustained increases in GH, IGF-1, and lean body mass with an acceptable safety profile (PMID 18981485).
This is rare in the peptide world — community doses directly mirror clinical trial dosing. 25 mg daily was the standard efficacy dose, 10 mg showed activity with diminished returns, and doses above 50 mg showed no additional benefit but increased side effects.
Stacking Protocols
Ipamorelin
20-25 mg PM
200-300 mcg SC
Ghrelin + GHRP synergy
CJC-1295
1-2 mg/week SC
Sustained GH + GHRH
GHRP-2/GHRP-6
GHRP
100 mcg post-workout
Baseline + acute spikes
MK-677's oral route means no injection site competition. It can run longer cycles than most injectables. Community protocols and trial oversight commonly describe closer blood sugar monitoring when combining multiple GH compounds.
Side Effects & Safety
Increased appetite — reported in the majority of trial subjects (Murphy et al., PMID 9467534), commonly pronounced in the first 1-2 weeks per community sources
Water retention/edema — mild to moderate; community sources describe it subsiding after 2-4 weeks
Mild insulin resistance — temporary and reversible upon discontinuation (Nass et al., PMID 18981485)
Lethargy/fatigue — community sources report this especially in the first 2-3 weeks
Joint stiffness — from water retention, community sources describe it as usually mild
Elevated prolactin — community sources report this in some individuals, typically not clinically significant
Carpal tunnel symptoms — rare, from water retention
Long-term safety (2-year Nass study): No significant changes in prostate, cardiovascular markers, or cancer incidence. The Nass et al. 2-year study described reversible mild insulin resistance and resolution toward baseline GH parameters within weeks of discontinuation.
Managing sides: Community protocols describe beginning at 10 mg, dosing before bed, managing carbohydrate intake for insulin sensitivity, and staying hydrated.
Core Supplies for This Protocol
The three essentials for running any reconstituted injectable: cold storage, accurate syringes, and metabolic tracking.
Cooluli Classic 4L Mini Fridge
Compact thermoelectric mini-fridge with heat/cool toggle. The most-mentioned dedicated peptide-storage fridge in research community sources — fits ~20 vials and runs quietly.
BD Ultra-Fine 31G 0.3cc 5/16" Insulin Syringes (Box of 90)
0.3cc 31G syringes — each gradation marks 1 unit (vs 2 units on 1cc), making sub-50-unit peptide doses accurate. BD Ultra-Fine is the most widely-cited brand in peptide community sources.
CONTOUR NEXT GEN Glucose Meter All-In-One Kit
Ascensia's CONTOUR NEXT GEN — the most clinically-validated home glucose meter. Includes 20 test strips + lancing device. Tracks the blood-sugar response GLP-1 users care about, especially during dose escalation.
