1-Testosterone Cypionate (DHB or Dihydroboldenone Cypionate)

1-Testosterone Cypionate (also known as DHB or Dihydroboldenone Cypionate) from Pharmaqo Labs is an injectable anabolic-androgenic steroid (AAS) at a concentration of 100mg per mL, typically sold in 10mL multi-use vials. It is a synthetic derivative of boldenone (a 5α-reduced form), structurally similar to Primobolan but lacking the methyl group at position 1 for oral bioavailability, making the injectable cypionate ester form the preferred administration method with a half-life of about 4-6 days.

Key Characteristics and Effects

Anabolic Potency: DHB is highly anabolic, often compared to or exceeding testosterone, nandrolone, or boldenone in promoting lean muscle growth, strength, and endurance without significant water retention or aromatization to estrogen. This leads to a harder, more defined physique, making it popular for cutting or recomp cycles.
Androgenic Profile: It binds selectively to androgen receptors with low conversion via 5α-reductase, reducing risks like acne, oily skin, hair loss, or prostate issues associated with DHT derivatives. Estrogenic sides (e.g., gynecomastia) are minimal due to negligible aromatization.
Pharmaqo Labs Specifics: This brand emphasizes pharmaceutical-grade purity (often >98.5%) with lab testing for authenticity. User reports highlight their DHB as relatively smooth with reduced post-injection pain (PIP) compared to other sources, especially at 100mg/mL when diluted or injected frequently. However, some reviews note mixed experiences with Pharmaqo products overall, including potential underdosing in other steroids, though DHB receives praise for effectiveness at lower doses (e.g., 100-200mg/week).

Typical Usage

Dosage: 200-400mg per week for men, split into 2-3 intramuscular injections (e.g., every 3-4 days) to maintain stable levels. Beginners may start lower (100-200mg/week). Cycles last 8-12 weeks, often stacked with testosterone for synergy. Not recommended for women due to virilization risks, though low doses (e.g., 25mg/day) have been anecdotally tolerated.
Administration Tips: Heat the oil, use smaller needles, and dilute with sterile oil or another steroid to minimize PIP, which can cause swelling, inflammation, or flu-like symptoms if dosed high or injected infrequently. Daily or every-other-day (EOD) pinning helps.

Potential Side Effects

Common: PIP/inflammation, joint dryness (possibly from low estrogen), testosterone suppression requiring PCT (e.g., hCG/Clomid).
Less Common: Hair loss (if predisposed), mood changes, or aggression; monitor liver/prostate health.
Legal/Health Note: DHB is a controlled substance in many countries (e.g., Schedule III in the US), not approved for medical use, and carries risks like hormonal imbalance or cardiovascular strain. Consult a doctor, get bloodwork, and avoid if inexperienced.
