Boldenone Undecylenate (EQ)

Name: Boldenone Undecylenate (EQ)
Brand: Quanta Pharmaceuticals

Equipoise, a long-acting testosterone derivative studied for lean gains, endurance and red blood cell increases.

Boldenone Undecylenate (EQ, Equipoise) is a testosterone derivative carrying a double bond between carbons 1 and 2, a modification that reduces both its androgenic and oestrogenic activity relative to testosterone. The attached undecylenate ester extends its half-life to roughly 14-16 days. Independent lab testing confirmed dosing at 323.38mg/ml for this batch, slightly above the 300mg/ml label claim.

Research Benefits

Lean muscle growth — Studied for steady, quality gains with comparatively little water retention.
Increased red blood cell production — Investigated for stimulating erythropoietin (EPO), supporting oxygen delivery and endurance.
Vascularity — Frequently studied for its effect on a leaner, more vascular appearance.
Appetite research — Often associated with increased appetite, relevant to caloric-surplus research protocols.
Extended half-life — A 14-16 day half-life supports infrequent-injection research protocols.

How It Works

Boldenone is structurally close to testosterone but carries an added double bond between carbons 1 and 2, which lowers its affinity for both the aromatase and 5-alpha reductase enzymes — reducing its conversion to both oestrogen and DHT relative to testosterone. The attached undecylenate ester, a long fatty-acid chain, extends its release out to roughly 14-16 days.

Boldenone binds the androgen receptor to drive nitrogen retention and protein synthesis, and has been separately studied for a pronounced stimulatory effect on erythropoietin (EPO) production in the kidneys, increasing red blood cell count — a mechanism of particular interest in endurance-focused research.
