What's up guys and gals? So, I am itching to throw Primo into my next cycle as I can get a really good deal on it. The thing is I run Test/EQ at 500/600 as the "base" for my cycles. I've run 600mg-1,200mg, my levels stay nearly the same as below for either dosage. EQ loves me and I love EQ.
Here's what I've run in the past:
Current Stats:
Rationale for Adding Primo:
Potential E2 Impact:
Thoughts? Concerns?
Here's what I've run in the past:
- Test/EQ Base: 500mg Test C and 600mg EQ weekly. I also donate double red blood cells every 16 weeks; 4 weeks prior, 13 weeks in, and last week of cycle.
Current Stats:
- Age: 43
- Gender: Male
- Height: 5' 9.75" <--Fuck off, lol.
- Weight: 185lbs
- Body Fat: 14-16%
- Weight: 190lbs - 200lbs
- Body Fat: 8-10%
- Hematocrit: 47% - 50% (on/off cycle) - Donating plasma for 5 years, I get this, and protein checked twice a week when I donate off cycle.
- SHBG: 12
- RBC: 5.37
- E2: 23
- HDL: 28
- LDL: 142 (Exploring statin options - any suggestions for cycle safe statins?)
- Triglycerides: 88
- Cholesterol/HDL Ratio: 6.7
- Prolactin: 4
- Blood pressure: 134/82 <--Average
- 500mg Test C
- 600mg EQ
- 50mg ED Var (adjust based on response)
- 500mg Test C
- 500mg Primo
- 600mg EQ
- 50mg ED Var
Rationale for Adding Primo:
- Lean Muscle Growth and Quality Gains: Both EQ and Primo promote lean muscle without significant water retention. Primo can potentially offset EQ's light water retention. Primo’s high anabolic to androgenic ratio makes it particularly effective for quality muscle gains.
- Endurance and Recovery: EQ increases red blood cell production, which can significantly enhance endurance and recovery. Primo complements this by aiding muscle recovery and preventing excessive muscle breakdown.
- Reduced Side Effects: EQ and Primo are relatively mild compared to other steroids. EQ is less likely to cause severe androgenic side effects, while Primo is known for its low androgenic activity and minimal liver toxicity. This combination could potentially lead to fewer side effects overall.
- Synergistic Effects:
- Enhanced Protein Synthesis and Nitrogen Retention: Both EQ and Primo are known to improve protein synthesis and nitrogen balance, crucial for muscle growth. Enhanced nitrogen retention means the body stays in an anabolic state, reducing muscle breakdown and supporting muscle growth.
- Complementary Anabolic Pathways: Both steroids interact with androgen receptors and also affect other anabolic pathways, such as increasing IGF-1 levels, which can further enhance muscle growth.
- Low Androgenic Load: The low androgenic activity of Primo and EQ means a lower risk of androgenic side effects like acne, hair loss, and prostate enlargement. Together, they provide substantial anabolic benefits while minimizing the potential for these issues.
- Muscle Hardness and Dryness: Primo is well known for enhancing muscle hardness and vascularity. It contributes to a more defined and "drier" look, which can be particularly beneficial during the latter stages of a bulk or leading into a cut. The combination of EQ and Primo should help achieve a lean, hard physique and potentially subvert water retention.
- Fat Loss and Lean Mass Preservation: Primo has a reputation for helping to preserve lean muscle mass while promoting fat loss, especially when paired with a proper diet and training regimen. It can help maintain muscle while reducing body fat (anecdotal), enhancing overall physique aesthetics.
- Increased Metabolic Rate: Both EQ and Primo can have a mild effect on increasing metabolic rate, which can assist in fat loss. EQ does this through its impact on red blood cell production and overall metabolism, while Primo supports a more active and lean physique.
E2 Considerations:
- Testosterone (500mg Test C):
- Testosterone is a potent aromatizer, converting into estrogen in the body at about a rate 20mg - 40mg of Estrogen / 100mg of Test C.
- Equipoise (600mg EQ):
- EQ has a much lower aromatization rate compared to testosterone. However, it can still convert to estrogen, though at roughly 50% of the rate of testosterone.
- Primobolan (500mg Primo):
- Primo does not aromatize into estrogen because it’s a DHT derivative. This means it won’t directly increase E2 levels. Instead, it can help manage estrogenic side effects indirectly by not contributing to estrogen buildup.
- Anavar (50mg ED): Anavar does not aromatize and therefore does not affect E2 levels.
Potential E2 Impact:
- High E2 from Test: High E2 from testosterone.
- Moderate E2 from EQ: EQ’s aromatization could contribute to E2 elevation, but its impact is lower than that of testosterone.
- Neutral E2 from Primo: Since Primo doesn’t affect estrogen levels, it won’t directly impact my E2, but it could balance out some of the effects from the testosterone and EQ.
Thoughts? Concerns?




how do you use it, the EQ. I’ve never ran it but I’d hope to get Ai benefits from it bc I aromatize like a bitch.
