Description
Quant Equipoise 500 (Boldenone Undecylenate):
Primary Use:
Quant Equipoise 500 contains Boldenone Undecylenate, a long-acting anabolic steroid derived from testosterone. Known commonly as “EQ” or Equipoise, it’s used by athletes and bodybuilders to promote lean muscle mass, improve vascularity, and enhance endurance and appetite. With a lower androgenic profile and a very long half-life, EQ is ideal for longer cycles, providing stable and slow gains with minimal estrogenic and androgenic side effects.
Mechanism of Action:
Boldenone Undecylenate is an anabolic compound that binds to androgen receptors, promoting increased nitrogen retention, protein synthesis, and red blood cell production. EQ has a mild estrogenic conversion, which helps support joint lubrication and muscle fullness without excessive bloating or water retention.
It is chemically similar to testosterone, but with an altered structure that reduces its androgenic activity and enhances its anabolic properties.
Common Uses:
-
Lean Mass Building: Favored in bulking cycles for quality, sustainable lean muscle gains without the puffiness or water weight.
-
Cutting Cycles: Helps preserve muscle mass and adds vascularity when in a calorie deficit.
-
Endurance & Conditioning: Increased red blood cell production improves oxygen transport, endurance, and recovery.
-
Appetite Stimulation: Boldenone is known to increase appetite, which can be helpful in mass-gaining phases.
Dosing Guidelines:
Men:
-
Typical dose: 300mg to 600mg per week
-
Administered in 1–2 injections per week due to long half-life
-
Cycle Length: 10 to 16 weeks (often 12 weeks or more to see full effect)
Women:
-
Not typically recommended due to long half-life and virilization risk
-
If used, doses should not exceed 50–100mg per week, with close supervision
Side Effects:
Estrogenic Side Effects:
-
Mild Aromatization: EQ converts to estrogen at about 50% the rate of testosterone, making water retention and gynecomastia unlikely at moderate doses.
-
Estrogen Control: Usually not required unless stacking with highly aromatizing compounds or running high doses; AI (e.g., Arimidex) optional.
Androgenic Side Effects:
-
Acne & Oily Skin: Possible but generally milder than testosterone.
-
Hair Loss: May occur in genetically predisposed users, though less likely than with more androgenic steroids.
-
Virilization in Women: Includes deepening of the voice, facial hair growth, and clitoral enlargement.
Cardiovascular Strain:
-
Can negatively impact lipid profile:
-
↓ HDL (good cholesterol)
-
↑ LDL (bad cholesterol)
-
Monitor cardiovascular health during long cycles.
-
Testosterone Suppression:
-
Like all anabolic steroids, EQ suppresses natural testosterone production. A proper Post Cycle Therapy (PCT) is required after the cycle.
Liver Toxicity:
-
EQ is non-hepatotoxic, making it safer for long-term use compared to oral steroids.
Injection Site Reactions:
-
Due to high concentration (500mg/ml), EQ may cause post-injection soreness, especially when using large volumes.
-
Splitting doses across injection sites can help.
-
Cycle Length:
-
Bulking Cycle: 12–16 weeks. Often stacked with:
-
Testosterone Enanthate or Cypionate
-
Dianabol or Anadrol (first 4–6 weeks)
-
-
Cutting Cycle: 10–14 weeks. Often stacked with:
-
Winstrol, Masteron, or Trenbolone for a lean, vascular look
-
Post Cycle Therapy (PCT):
-
Start PCT: 2–3 weeks after the last injection (due to the long half-life)
-
Compounds: Nolvadex (Tamoxifen) or Clomid (Clomiphene) for 4–6 weeks
-
Purpose: To restore natural testosterone levels, prevent muscle loss, and maintain gains
Stacking:
Common Stacks:
-
For Bulking:
-
EQ + Test Cyp + Dianabol
-
EQ + Test E + Deca Durabolin
-
-
For Cutting:
-
EQ + Test Prop + Winstrol
-
EQ + Tren Ace + Anavar
-
With Aromatase Inhibitors:
-
Not always required, but AIs like Arimidex or Aromasin may be used if estrogen-related issues appear.
Notes:
-
Injection Frequency: Due to its long undecylenate ester, EQ can be injected just once per week—but many prefer splitting the dose into two injections per week to maintain smoother blood levels.
-
Slow Acting: Gains come gradually but consistently; best suited for longer cycles.
-
Appetite Boost: EQ can dramatically increase appetite, which may be beneficial in bulking phases—but should be managed in cutting cycles.
-
High Concentration Consideration: At 500mg/ml, users should be aware of injection volume tolerance. Smaller, more frequent injections may help reduce PIP (post-injection pain).
