Comparing the serms
Half-life and storage side by side, which is where the practical differences in this group show up.

| Compound | Half-life | Storage |
|---|---|---|
| Clomid | Mixed: the zuclomiphene isomer persists far longer than enclomiphene, which is why washout is prolonged. | Cool, dry, dark. |
| Tamoxifen | Long, approximately 5 to 7 days, with an active metabolite longer still. | Cool, dry, dark. |
