Why You Should Buy Xeno Labs Primobolan – 100mg/10ml at Steroiduck?
What It Does
Primobolan 100 contains Methenolone Enanthate at 100mg per ml – widely considered the safest and mildest injectable steroid available. Originally developed for treating muscle wasting diseases and malnutrition, Primobolan is famous for producing high-quality, permanent muscle gains with virtually no side effects.
When you inject Primobolan, it increases nitrogen retention and protein synthesis at a moderate rate. Unlike harsh compounds that produce dramatic but temporary gains, Primobolan builds real muscle tissue slowly and steadily. The gains are 100% keepable – what you build stays on your frame permanently after PCT.
The enanthate ester means you only need to inject twice weekly for stable blood levels. Within 2-3 weeks, you’ll notice improved muscle fullness, enhanced recovery, and steady strength increases. The beauty of Primobolan is what it doesn’t do – no water retention, no gyno, no hair loss for most users, minimal testosterone suppression compared to other steroids.
The Main Benefits For You
Quality Muscle You Keep Forever
Primobolan produces 8-12 pounds of pure muscle over 12-16 week cycles. These aren’t water-weight gains that disappear – it’s real tissue that stays permanently. Studies show users keep 90-95% of Primobolan gains post-cycle, compared to 50-60% with wet compounds like Dianabol.
Zero Water Retention
Primobolan doesn’t aromatize to estrogen at all. Your muscles stay dry, hard, and defined throughout your cycle. You never wake up looking puffy or bloated. This makes it perfect for lean bulking when you want quality mass without getting fat or holding water.
Safest Side Effect Profile
With an extremely low androgenic rating and no estrogenic activity, Primobolan has fewer side effects than any other injectable steroid. No gyno risk. Minimal acne. Very little hair loss even for those genetically predisposed. Women can use it at low doses with minimal virilization risk.
No Liver Toxicity
Despite being available in oral form, injectable Primobolan is not hepatotoxic. Your liver stays healthy throughout your cycle. You can run it for extended 16-20 week periods without organ damage concerns.
Excellent for Cutting
Primobolan shines during cutting phases. It preserves muscle tissue when eating in a calorie deficit better than almost any compound. You lose fat while maintaining every pound of muscle you worked hard to build. Many competitors use it for entire 16-week contest prep.
Mild Testosterone Suppression
While all steroids suppress natural testosterone, Primobolan causes less suppression than most compounds. Your HPTA recovers faster post-cycle. Some users even run Primobolan-only cycles (though testosterone base is still recommended).
Works for Women
At 50-75mg weekly, women can use Primobolan with minimal masculinizing effects. It’s one of the few injectables suitable for female athletes seeking quality muscle without severe virilization.
FDA DISCLAIMER: This product isn’t intended to diagnose, treat, cure, or prevent any disease. Methenolone Enanthate is a controlled substance and should only be used under proper medical supervision for legitimate medical purposes.
Recommended Dosage for Male:
400-800mg per week split into two injections. Beginners start with 400-500mg weekly (4-5ml total). Intermediate users run 500-700mg weekly. Advanced users go to 700-800mg weekly. Split into two injections per week: Monday and Thursday.
Recommended Dosage for Female:
50-100mg per week for women who choose to use it. Start at 50mg weekly (0.5ml) and monitor closely for any masculine side effects. Stop immediately if voice deepening occurs.
Injection Frequency:
Due to 5-7 day half-life, inject twice weekly for stable blood levels. Example: For 600mg weekly, inject 300mg (3ml) Monday morning and 300mg Thursday evening.
When to Inject:
Inject deep into muscle (glutes, thighs, or shoulders) using 1-1.5 inch needle. Rotate injection sites each time. Primobolan is oil-based and flows smoothly with minimal post-injection pain.
Cycle Duration:
12-20 weeks for optimal results. Primobolan's mild nature allows longer cycles than harsh compounds. Most users run 16 weeks for maximum quality gains. The compound takes 4-5 weeks to fully saturate and show results.
Stacking:
Always stack with testosterone base for best results. Classic stack: 600mg Primobolan weekly + 500mg Testosterone Enanthate weekly for lean mass building. Cutting: 500mg Primobolan + 350mg Testosterone + 50mg Anavar daily for extreme conditioning.
Post Cycle Therapy (PCT):
Required after cycle ends. Wait 2 weeks after last injection (enanthate ester needs to clear), then start PCT: Nolvadex 40/40/20/20mg daily + Clomid 50/50/25/25mg daily for 4 weeks.
Most Common:
- Mild to moderate testosterone suppression (less than most steroids)
- Minimal acne (much less than testosterone)
- Slight oily skin
- Possible mild hair shedding (rare, much less than DHT derivatives)
- Negative cholesterol impact (HDL decreases moderately)
Serious Side Effects:
- Complete testosterone suppression with very high doses or extended use
- Cardiovascular strain with poor lipid management
- Possible prostate effects in older users
How to Manage:
Get blood work at week 8 checking testosterone, estradiol, cholesterol. Do cardio 3-4x weekly. Take fish oil 4-6g daily for cardiovascular health. Use testosterone base to prevent low testosterone symptoms.

Classification:
DHT (dihydrotestosterone) derivative, long-acting ester
Mechanism of Action:
Methenolone is DHT with additional double bond at carbon 1-2 and methyl group at carbon 1. This modification increases anabolic activity while reducing androgenic effects. Increases protein synthesis and nitrogen retention moderately. Does not aromatize to estrogen. Enhances immune function. Mild anti-catabolic effects preserve muscle during calorie deficits.
Half-Life:
5-7 days (some sources report up to 10-14 days)
Detection Time:
4-5 months after last injection in advanced drug testing
Bioavailability:
High (oil-based intramuscular injection provides excellent absorption)

88:44-57 (moderate anabolic, very low androgenic)

None - Cannot convert to estrogen

Is already DHT derivative (no conversion)
Hepatotoxicity:
None for injectable version (oral version has mild liver impact)
