Estrogen & Prolactin Control in Canada | Aromatase Inhibitors and Dopamine Agonists
Estrogen and prolactin management compounds are essential ancillaries in anabolic steroid research. When androgens aromatise to estrogen in excess or when progestin based compounds elevate prolactin. The downstream effects on research outcomes, body composition, and hormonal balance can be significant. Canada Steroid Depot stocks the full range of aromatase inhibitors (AIs), selective oestrogen receptor modulators (SERMs), and dopamine agonists used to manage oestrogen and prolactin throughout and after anabolic research cycles.
Aromatase inhibitors (AIs)
Aromatase inhibitors work by blocking the aromatase enzyme (CYP19A1). The enzyme responsible for converting androgens such as testosterone into estrogens. By inhibiting aromatase activity, AIs reduce circulating estradiol levels and prevent estrogen related side effects in anabolic research contexts. CSD stocks the three most widely researched AIs: Anastrozole (Arimidex), a non steroidal AI typically dosed at 0.5–1mg every other day; Letrozole, the most potent non steroidal AI capable of reducing estrogen by up to 98%; and Exemestane (Aromasin), a steroidal AI that permanently binds and inactivates the aromatase enzyme; preventing estrogen rebound on cessation.
Prolactin control; dopamine agonists
Prolactin elevation is associated with the use of progestin based anabolic compounds such as Nandrolone (Deca-Durabolin), Trenbolone, and Anadrol. Elevated prolactin can suppress testosterone production, reduce libido, and cause lactation in male subjects. Dopamine agonists work by stimulating D2 dopamine receptors in the pituitary gland, which directly inhibits prolactin secretion. CSD stocks Cabergoline (Dostinex) the most selective and well tolerated prolactin antagonist used in anabolic research and Pramipexole (Mirapex) as an alternative option for prolactin management.
SERMs vs AIs; when to use each
Selective estrogen receptor modulators (SERMs) such as Tamoxifen (Nolvadex) and Raloxifene block estrogen receptors in specific tissues; particularly breast tissue, without reducing circulating estradiol levels. SERMs are generally preferred for gynecomastia management and post cycle therapy (PCT). While AIs are preferred for in cycle estrogen control where reducing total estradiol is the goal. CSD stocks both compound classes. SERMs are available in our PCT category, while AIs are stocked here alongside prolactin control compounds.
HPLC testing and domestic shipping
Every estrogen and prolactin control compound stocked by Canada Steroid Depot is independently HPLC tested by accredited third party laboratories before listing. Results confirm active compound identity and concentration accuracy. Certificates of analysis are available on request for any lot number. All orders ship from within Canada via tracked Canada Post or courier. No customs, no border risk, plain discreet packaging, same day dispatch on orders before 1pm EST.
Frequently asked questions
CSD stocks Anastrozole (Arimidex), Letrozole, and Exemestane (Aromasin) as aromatase inhibitors. We also stock Tamoxifen (Nolvadex) and Raloxifene as SERMs for estrogen receptor blockade. Check the category page for current availability and stock status.
CSD stocks Cabergoline (Dostinex) and Pramipexole (Mirapex) for prolactin management in anabolic research protocols. Cabergoline is the most widely used option due to its high selectivity for D2 receptors and once or twice weekly dosing schedule.
Anastrozole and Letrozole are both non steroidal aromatase inhibitors. They bind reversibly to the aromatase enzyme. Letrozole is significantly more potent, capable of suppressing estradiol by up to 98%. Exemestane is a steroidal AI that permanently inactivates aromatase enzymes, making it a suicidal AI. This prevents estrogen rebound on discontinuation, which can occur with non steroidal AIs.
Aromatase inhibitors reduce total circulating estradiol and are preferred for in cycle estrogen management. SERMs block estrogen receptors in specific tissues without lowering total estrogen and are preferred for gynecomastia management and post cycle therapy. In some research protocols both are used concurrently for different purposes.
CSD stocks both pharmaceutical grade products from licensed manufacturers and compounds from verified domestic suppliers. All products are independently HPLC tested for concentration accuracy regardless of source. Pharma grade products are clearly identified in each listing.
