HGH Fragment 176-191 — Dosing, Cycles, Half-Life & Side Effects
HGH Fragment 176-191 is a growth hormone fragment peptide with a half-life of 30 minutes. The lipolytic fragment of human growth hormone (amino acids 176-191). Promotes fat burning by stimulating lipolysis and inhibiting lipogenesis without the growth-promoting or diabetogenic effects of full HGH.

Typical Dosing Ranges
Common dose range: 250-500mcg twice daily (AM fasted, pre-bed)
Cycle length: 8-12 weeks
Dose ranges are compiled from published pharmacokinetic studies and community-reported usage. Where a value is community-reported rather than clinically studied, this page and its structured data flag it. Lower end of any range is always the safer starting point.
Stacking Considerations
- No structural stacking blockers. Standard harm-reduction rules apply: minimize total androgen load, minimize oral exposure, and monitor bloodwork.
PCT Requirements
- Never stack two SERMs. Extend a single SERM (tamoxifen OR enclomiphene/clomiphene) rather than combining.
- Use the cycle planner to generate a full protocol based on your complete stack, not this compound alone.
Side Effect Profile
- Very short half-life
- Requires multiple daily injections
- Must be taken fasted
- Expensive
- Limited human clinical data
Known Interactions
mk677 + HGH Fragment 176-191
minor — synergisticMK-677 and GH both increase GH/IGF-1. May cause excessive GH-related sides.
Recommendation: Generally redundant. Choose one for cost-effectiveness.
Monitor: IGF-1, Blood glucose, Water retention

Monitoring (Bloodwork & Vitals)
- Comprehensive metabolic panel (baseline, mid-cycle, post-cycle)
- Lipid panel (total cholesterol, HDL, LDL, triglycerides)
- CBC (hemoglobin, hematocrit — watch for erythrocytosis)
- Sex-hormone panel (Total T, Free T, Estradiol sensitive, SHBG, LH, FSH)
- Blood pressure (weekly self-check; flag systolic >140 or diastolic >90)
Baseline bloodwork is recommended before any cycle. Discontinue if liver enzymes exceed 3× upper limit of normal or if hematocrit exceeds 54%.
