Semaglutide (Ozempic/Wegovy) is a GLP-1 receptor agonist with a half-life of ~7 days (168 hours). FDA-approved GLP-1 receptor agonist for weight management. Not a PED — acts through appetite suppression and metabolic regulation. No HPTA interaction, no hepatotoxicity. Subcutaneous injection once weekly.

Typical Dosing Ranges
Common dose range: 0.25-2.4mg/week (titrate slowly)
Cycle length: 12-52 weeks
Time to steady state: ~35 days
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
- Depot clearance estimate: ~35 days post-last-dose before SERM start (5 × apparent depot half-life of 168h).
- 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
- GI side effects (nausea, diarrhea, constipation)
- Very expensive (~$800-1000/month without insurance)
- Must maintain high protein intake to preserve muscle
- Requires slow dose titration (12-20 weeks)
- Potential muscle loss without resistance training

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%.
