Aromaxyl is Kalpa Pharmaceuticals exemestane, 25 mg per tablet, one strength, one pack. It is an aromatase inhibitor of the steroidal kind, and the difference from the non-steroidal inhibitors is worth understanding before the first tablet: this one does not simply block the enzyme while it is present, it disables it.
Exemestane is described in the literature as a false substrate - the enzyme accepts it, tries to work on it, and is left inactive. Because the body has to manufacture new enzyme to restore aromatization, the effect outlasts the drug itself by days. That single fact explains the dosing rhythm, the way over-suppression creeps in, and why a blood test is the only honest guide.
Product Overview
The oral half-life is quoted at twenty-four hours, while the duration of action is put at four to five days. Exemestane is classified as type I inhibition, in contrast to the reversible type II behaviour of anastrozole: the enzyme is inactivated rather than merely occupied.
It does not suppress the gonadal axis, is not alkylated, and carries no meaningful hepatic risk. What it does carry is the risk of taking estrogen too low. Estrogen is involved in joint comfort, libido and lipid balance, so the target is a band rather than a floor, and the band is found with a laboratory result instead of a feeling.
The listing is the plain 25 mg tablet in a single strength, and the format this drug normally ships in is a hundred of them. The working unit on a course is half of one, so a tablet splitter sits next to the pack rather than in a drawer somewhere. Two boundaries belong at the front: the drug is not for premenopausal women outside medical supervision, and it is never a plan on its own, because with nothing aromatising the enzyme it targets is idle.
Dosage Protocol
Amounts are oral totals, and the alternate-day pattern is normal here for the reason described above. Only a confirmed high estradiol justifies the higher figures.
| Beginner | 12.5 mg on alternate days, which is half a tablet every second day |
| Intermediate | 12.5-25 mg on alternate days through the course, checked with a panel |
| Advanced | 25 mg a day only where aromatization is heavy and a blood test confirms it |
| Female | Not used in this context; premenopausal women are not candidates for the drug outside medical supervision |
| Administration | Oral, usually on alternate days, at a consistent time, with a tablet splitter for 12.5 mg |
Suggested Protocols
It belongs beside an aromatizing course, and the sensible pattern is small and measured rather than large and reactive.
What to Expect
- Estradiol drops in the first fortnight. Estrogen-dependent puffiness and breast tenderness are the first things to improve.
- The effect hangs around. A dose taken today keeps aromatization suppressed for several days, which is the reason for the alternate-day schedule.
- Too low feels like drying out. Flushes and sweating are the fingerprint of estrogen that has been pushed under the useful band.
- Joints are the common complaint. Aching and stiffness during use usually mean the dose, not the course, is the problem.
- Big doses are not neutral. Supraphysiological amounts have been associated with androgenic effects of their own, including acne.
- Long use has a monitoring cost. Estrogen matters to lipids and bone, so extended exposure needs eyes on more than one marker.
Side Effects and Management
As with every inhibitor, the adverse list is mostly the picture of low estrogen.
Removing the Inhibitor and Follow-Up
There is no hormonal restart to run for exemestane. The question is only when to take it out of a plan that relied on it.
Storage and Ordering
A dry cupboard at room temperature, the pack closed, batch and expiry checked on arrival. A tablet splitter is worth owning at this strength, because half a tablet is the common working dose.
Aromaxyl is on the Kalpa Pharmaceuticals catalogue beside the rest of the support range: Arimixyl as the reversible option, Letroxyl for the cases that resist both, Nolvaxyl for receptor-level control and Clomixyl for recovery. Orders leave in plain packaging and both dispatch options are shown on each page.
