We offer exemestane for sale as Exemestane 25 mg/tab, 100 tabs. Exemestane is a steroidal aromatase inactivator, and ZPHC supplies it at 25 mg per tablet as a 100-tablet supply. Aromatase is the enzyme that converts androgens into estrogens, and exemestane is unusual within the inhibitor class because it is structurally related to the substrate it attacks.
How a steroidal inactivator works
The enzyme recognises exemestane as a substrate and processes it, but the product of that reaction binds irreversibly to the enzyme's active site, leaving that enzyme molecule unable to convert further androgen. This is suicide inhibition, and it is why the effect is described as inactivation rather than reversible blockade. Nonsteroidal inhibitors such as anastrozole bind reversibly and are cleared from the enzyme. Both lower estrogen synthesis; the difference is in how the enzyme is left afterwards.
Why it is not a SERM
A selective estrogen receptor modulator such as tamoxifen acts at the receptor, blocking or modulating estrogen signalling without changing how much estrogen is made. Exemestane reduces the amount made, so the receptor has less to bind. The two approaches are not interchangeable, and neither is a general-purpose hormone balancer: estrogen has functions in bone, lipids and other tissue, and reducing it substantially has consequences that are monitored rather than assumed.

Frequently Asked Questions
What is the active substance in the exemestane for sale offered here?
Exemestane is a steroidal aromatase inactivator, and ZPHC supplies it at 25 mg per tablet as a 100-tablet supply.
What mechanism should I understand before I buy exemestane?
The enzyme recognises exemestane as a substrate and processes it, but the product of that reaction binds irreversibly to the enzyme's active site, leaving that enzyme molecule unable to convert further androgen.
Which related compounds should I distinguish before I buy exemestane?
Exemestane inactivates aromatase irreversibly, whereas anastrozole is a reversible nonsteroidal inhibitor. Tamoxifen is different again: it acts at estrogen receptors rather than inhibiting aromatase. The enzyme recognises exemestane as a substrate and processes it, but the product of that reaction binds irreversibly to the enzyme’s active site. This is suicide inhibition, and it is why the effect is described as inactivation rather than reversible blockade.
How can I check authenticity if I buy exemestane online?
Check the product's authenticity code on the manufacturer's official website after receipt. Keep the code with the batch and expiry details. The product is supplied directly by its manufacturer.
What does exemestane cost cover for this item?
The price concerns Exemestane 25 mg/tab, 100 tabs. Read it as a quotation for this product, with the declared amount and form, rather than as a quotation for an unspecified product.
How can I compare exemestane cost across different quantities?
Compare the same active substance and formulation. For an unambiguous quantity, divide the quoted price by the stated number of units or declared amount. This gives a purchase-price comparison, not an administration schedule.
Can I compare exemestane cost directly with the price of a different substance?
A price comparison does not make different substances interchangeable. This item is Exemestane 25 mg/tab, 100 tabs; retain its active-ingredient and any analogue, ester or blend designation when comparing it with alternatives.
Does exemestane cost tell me the strength of the product?
No. Price and ingredient strength describe different things. Use the stated strength or concentration to identify the product; a higher or lower quoted price is not a different strength.
