Why You Should Buy Xeno Labs Nandrolone Decanoate – 300mg/10ml at Steroiduck?
What It Does
Nandrolone Decanoate is pure Deca at 300mg per ml – one of the most popular muscle-building compounds ever created. This is the same nandrolone that’s been used by bodybuilders since the 1960s to pack on serious size. Xeno Labs gives you 300mg concentration so you inject less total volume.
When you use Nandrolone Decanoate, your body grabs way more protein from your food and uses it to build new muscle tissue. Your nitrogen retention goes way up. Your muscles stay in growth mode 24/7. Within the first month, you’ll notice your body looking fuller and your weight climbing steadily.
The best part? Nandrolone Decanoate makes your beat-up joints feel incredible. Years of heavy lifting damage your joints. This compound produces special fluid that cushions your joints like nothing else. Your knees stop hurting. Your elbows feel better. You can finally train the way you want to.
The Main Benefits For You
Build Quality Muscle That Stays
You can gain 15-20 pounds of solid muscle over a 12-16 week cycle if you’re training hard and eating right. This isn’t water weight that disappears – it’s real muscle tissue. Your arms get thicker. Your chest expands. Your legs get bigger. People notice you growing every week.
Your Joints Finally Feel Good
This is huge. Nandrolone Decanoate increases collagen production in your joints and tendons. Within 3-4 weeks, that knee pain during squats starts going away. Your elbows stop aching on bench press. Your shoulders feel less worn down. You can train heavy without constant pain limiting you.
Recover Way Faster
After a brutal workout, your muscles normally need days to recover. With Nandrolone Decanoate, you recover overnight. The next day you’re ready to train again. You can handle more volume, hit muscles more often, and make faster progress because recovery time gets cut in half.
Less Injection Volume
Because this is 300mg per ml instead of regular 200mg, you inject smaller amounts. Want 600mg per week? That’s only 2ml total instead of 3ml. Smaller injections mean less soreness, easier to rotate sites, and more comfortable cycles.
Works for Multiple Goals
Nandrolone Decanoate is versatile. Use it for serious bulking when you want maximum size. Use it during lean bulking for quality gains without excess fat. Even use it while cutting to protect your muscle when eating less food.
Long-Lasting Effects
The decanoate ester is long-acting. After each injection, it keeps working in your body for 2+ weeks. Your blood levels stay stable. Your muscles get constant anabolic stimulation. You don’t deal with hormone ups and downs that mess with your mood and energy.
FDA DISCLAIMER: This product isn’t intended to diagnose, treat, cure, or prevent any disease. Nandrolone Decanoate is a controlled substance and should only be used under proper medical supervision for legitimate medical purposes.

Recommended Dosage for Male:
300-600mg per week. Beginners start with 300-400mg weekly (1-1.33ml total per week). Intermediate users run 400-500mg weekly. Advanced users sometimes go to 600mg weekly. Split into one or two injections per week - either once weekly or split Monday/Thursday.
Recommended Dosage for Female:
50-100mg per week if you choose to use it. Women should start at 50mg weekly and watch closely for any masculine side effects like voice changes or body hair. Stop immediately if these appear.
When to Inject:
Inject deep into muscle (glutes, thighs, or shoulders). If doing 600mg weekly, split into two 300mg shots (1ml each) on Monday and Thursday. Rotate injection sites each time to avoid scar tissue buildup.
Cycle Duration:
12-16 weeks minimum. Nandrolone Decanoate takes 3-4 weeks to fully kick in due to the long ester. Running shorter than 12 weeks wastes the compound. Most experienced users prefer 14-16 week cycles for maximum results.
Stacking:
Always stack with testosterone base. Never run Nandrolone alone or your libido will crash and you'll feel terrible. Common stack: 400mg Nandrolone weekly + 500mg Testosterone weekly for serious mass building.
Post Cycle Therapy (PCT):
Absolutely required. Nandrolone suppresses your natural testosterone hard and affects prolactin. Wait 3-4 weeks after your last injection (long ester needs time to clear). Then start PCT: Nolvadex 40/40/20/20mg daily + Clomid 50/50/25/25mg daily for 4 weeks. Consider Cabergoline 0.25mg twice weekly during cycle for prolactin control.
Important Timing:
Because of the long ester, you won't feel Nandrolone working immediately. Be patient. By weeks 3-4, you'll notice your muscles getting fuller, your joints feeling better, and your recovery improving dramatically.
Most Common:
- Your body stops making natural testosterone completely during cycle
- Some water retention (less than many compounds but still present)
- Possible libido issues if testosterone dose isn't high enough
- Prolactin increase can cause nipple sensitivity in some users
- Oily skin and acne on back or chest
- Takes 3-4 weeks to clear system after stopping
Less Common But Important:
- Gyno from prolactin (different from estrogen-caused gyno)
- High blood pressure if retaining water
- Bad cholesterol numbers on blood work
- Low energy without proper testosterone base
- Hair shedding if male pattern baldness runs in your family
- "Deca dick" - erectile issues from prolactin or low testosterone ratio
How to Manage:
Always run testosterone at equal or higher dose than Nandrolone. Take Cabergoline 0.25mg twice weekly to control prolactin. Use Arimidex for estrogen control. Get blood work at week 8 to check prolactin, estrogen, and testosterone levels. Stay hydrated. Do cardio for cardiovascular health.
Active Ingredient:
Nandrolone Decanoate (19-nortestosterone decanoate)
Dosage Strength:
300 mg per 1 milliliter
Quantity:
10ml vial (3000mg total per vial)

Injectable oil-based solution in sterile multi-dose vial
Intended Use:
Primary medical use: Treating anemia of chronic kidney disease, osteoporosis in postmenopausal women, muscle wasting diseases.
Primary bodybuilding use: Off-season bulking cycles, mass building, joint relief during heavy training, long growth phases, muscle preservation during cuts.
Classification:
19-nor anabolic androgenic steroid, long-acting ester
Mechanism of Action:
Nandrolone binds to androgen receptors in muscle tissue with high affinity. Increases protein synthesis and nitrogen retention. Enhances collagen synthesis in connective tissue. Stimulates erythropoietin production (red blood cell formation). Has approximately 37% less androgenic activity than testosterone while maintaining strong anabolic effects. Does not convert to DHT but converts to a weaker metabolite (dihydronandrolone).
Half-Life:
6-7 days (allows once or twice weekly injections)
Duration of Action:
14-16 days (effects continue long after half-life)
Active Life in Body:
Approximately 2-3 weeks after injection
Detection Time:
12-18 months after last injection in advanced drug tests (important for tested athletes)
Bioavailability:
High (oil-based intramuscular injection provides excellent absorption)
Anabolic/Androgenic Ratio:
125:37 (highly anabolic, low androgenic compared to testosterone's 100:100)
Aromatization:
Low - Converts to estrogen at approximately 20% the rate of testosterone
Progestogenic Activity:
Moderate - Has progesterone receptor binding activity which can contribute to side effects
Molecular Formula:
C28H44O3
Molecular Weight:
428.65 g/mol
Chemical Name:
19-nor-4-androstene-17β-ol-3-one decanoate
Administration:
Deep intramuscular injection into glutes, thighs, or deltoids. Use 1-1.5 inch needle for proper depth. Inject slowly over 30-45 seconds.
