Typical Dosing Ranges

Common dose range: 1-2mg/day subcutaneous or topical application

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

Short half-life
Primarily cosmetic applications
Injectable form less common
Can cause skin irritation topically

Known Interactions

No compound-specific interactions are catalogued in the current matrix. This does not mean no risk exists — it means there is no curated pairwise entry.

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%.
