Why You Should Buy Xeno Labs Nandrolone Phenylpropionate (NPP) – 100mg/10ml at Steroiduck?
What It Does
Nandrolone Phenylpropionate 100 contains NPP at 100mg per ml – the fast-acting version of the famous nandrolone compound. This is the same muscle-building nandrolone that’s been used since the 1960s, but with a short phenylpropionate ester that kicks in within 7-10 days instead of taking 4-5 weeks like Deca.
When you inject NPP, your body dramatically increases protein synthesis and nitrogen retention. Your muscles stay in constant growth mode. Your joints produce special lubricating fluid that makes years of training damage feel better. Within the first two weeks, you’ll notice your muscles looking fuller and your nagging joint pain starting to disappear.
The short ester means you inject every other day or every 3 days instead of once weekly. While this is more frequent than long esters, it gives you more control – stable blood levels, faster results, and the ability to stop quickly if needed.
The Main Benefits For You
Rapid Joint Relief
This is what makes NPP special. Within 2-3 weeks, your beat-up joints feel incredible. That knee pain during squats disappears. Your elbows stop aching on bench press. Your shoulders feel less worn down. NPP increases collagen synthesis in joints and tendons, providing real healing – not just pain masking.
Faster Results Than Deca
While Deca Durabolin takes 4-5 weeks to fully kick in, NPP starts working within 7-10 days. You see your muscles getting fuller faster. Strength increases earlier. Recovery improves quicker. For 8-10 week cycles, this matters – you’re seeing results for more of your cycle instead of waiting.
Build Quality Lean Muscle
You can gain 12-18 pounds of solid muscle over an 8-10 week NPP cycle with proper training and nutrition. This isn’t water weight – it’s real muscle tissue that stays on your frame after PCT. Your physique improves steadily week by week.
Less Water Retention
NPP causes less bloat than testosterone and even slightly less than Deca. Your muscles look full but defined. You don’t wake up puffy. This makes NPP excellent for lean bulking when you want quality mass without excessive water.
Recover Way Faster
After brutal workouts, you recover overnight with elevated nandrolone levels. The next day you’re ready to train again. You can handle more volume, train muscles more frequently, and make faster progress because recovery time is cut dramatically.
Flexible Cycle Control
The short phenylpropionate ester clears your system in 7-10 days after stopping. If you experience side effects, stopping provides relief quickly. When your cycle ends, you can start PCT sooner – waiting only 5-7 days instead of 3-4 weeks like Deca.
Perfect for Shorter Cycles
While Deca requires 12-16 week cycles minimum, NPP works great for 8-10 week cycles. The fast-acting ester saturates quickly and clears quickly, making it ideal when you want results without committing to 4-month cycles.
FDA DISCLAIMER: This product isn’t intended to diagnose, treat, cure, or prevent any disease. Nandrolone Phenylpropionate 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 split into frequent injections. Beginners start with 300-400mg weekly. Intermediate users run 400-500mg weekly. Advanced users sometimes go to 600mg weekly. Split weekly dose into injections every other day (EOD) or every 3 days.
Injection Schedule Examples:
For 400mg weekly: Inject 100mg Monday, Wednesday, Friday, Sunday (repeating pattern).
Or: Inject 133mg Monday, Thursday, Sunday (every 3 days).
The key is maintaining stable blood levels with frequent injections due to 4-5 day half-life.
Recommended Dosage for Female:
50-100mg per week if choosing to use. Women should start at 50mg weekly (injecting 25mg twice weekly) and monitor closely for masculine side effects. Stop immediately if voice deepening occurs.
When to Inject:
Inject deep into muscle (glutes, thighs, or shoulders) using 1-inch needle. Due to frequent injections, rotate sites religiously to prevent scar tissue. Many users inject glutes Monday/Thursday, thighs Tuesday/Friday, shoulders Wednesday/Saturday pattern.
Cycle Duration:
8-10 weeks is optimal for NPP. The short ester allows effective shorter cycles. Can run up to 12 weeks but most users prefer 8-10 weeks to minimize side effects while maximizing results.
Stacking:
Always stack with testosterone base. Common stack: 400mg NPP weekly + 400-500mg Testosterone Propionate or Enanthate weekly for lean mass building. The short ester of NPP pairs well with Test Prop (also short ester) for aligned injection schedules.
Post Cycle Therapy (PCT):
Required after cycle ends. NPP clears quickly - wait only 5-7 days after last injection, 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:
NPP reaches peak blood levels within 5-7 days due to short ester. You'll notice effects by days 7-10. Maximum saturation occurs by week 2-3. This fast action is NPP's main advantage over Deca.
Most Common:
- Complete testosterone suppression during cycle
- Moderate water retention (less than testosterone, similar to Deca)
- Possible libido issues if testosterone ratio isn't adequate
- Prolactin elevation can cause nipple sensitivity (need Cabergoline)
- Oily skin and acne on back or chest
- Frequent injections required (EOD or every 3 days)
Less Common But Important:
- Gyno from prolactin activity (different mechanism than estrogen)
- Elevated blood pressure if retaining water
- Negative cholesterol impact on blood work
- "Deca dick" - erectile issues from prolactin or improper test ratio
- Hair shedding if male pattern baldness runs in family
- Takes longer to clear than claimed for some users
How to Manage:
Run testosterone at equal or higher dose than NPP. Take Cabergoline 0.25mg twice weekly for prolactin control. Use Arimidex if experiencing estrogen sides. Get blood work at week 5-6 to check prolactin, estrogen, testosterone. Stay hydrated. Do cardio for cardiovascular health.
Critical Note:
NPP has the same progestogenic activity as Deca. The prolactin-induced gyno and libido issues can occur. Cabergoline prevents these effectively. Don't skip prolactin management.
Active Ingredient:
Nandrolone Phenylpropionate (19-nortestosterone phenylpropionate)
Dosage Strength:
100 mg per 1 milliliter
Quantity:
10ml vial (1000mg total per vial)
Form:
Injectable oil-based solution in sterile multi-dose vial
Intended Use:
Primary medical use: Treating anemia, muscle wasting, osteoporosis (historical - rarely prescribed currently).
Primary bodybuilding use: Lean bulking cycles, joint relief during training, shorter growth phases where Deca's long ester isn't practical, recomposition cycles.
Classification:
19-nor anabolic androgenic steroid, short-acting ester
Mechanism of Action:
Nandrolone binds to androgen receptors with high affinity. Increases protein synthesis and nitrogen retention significantly. Enhances collagen synthesis in connective tissue (joint relief mechanism). Stimulates erythropoietin production. Does not convert to DHT; instead converts to weaker metabolite dihydronandrolone. Has moderate progestogenic activity.
Half-Life:
4-5 days (requires injection every other day or every 3 days)
Active Life in Body:
7-10 days after injection
Detection Time:
12-18 months in advanced drug testing (metabolites remain detectable long-term)
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 which can contribute to side effects including prolactin elevation
Molecular Formula:
C27H34O3
Molecular Weight:
406.56 g/mol
Chemical Name:
19-nor-4-androstene-17β-ol-3-one 17β-phenylpropionate
Administration:
Deep intramuscular injection into glutes, thighs, or deltoids. Use 1-1.5 inch needle. Inject slowly over 20-30 seconds. Rotate sites frequently due to injection frequency.
Storage:
Store at room temperature (68-77°F or 20-25°C) away from light. Do not refrigerate. Do not freeze. Keep out of reach of children.
