Why You Should Buy Xeno Labs Testosterone Propionate – 100mg/10ml at Steroiduck?
What It Does
Testosterone Propionate 100 contains Testosterone Propionate at 100mg per ml – the shortest-acting ester of testosterone available. This is pure testosterone attached to a propionate ester that releases the hormone rapidly, with effects starting within 24-48 hours of your first injection.
When you inject Testosterone Propionate, it works identically to longer testosterone esters in terms of muscle building, strength gains, and overall effects. The difference is speed – you don’t wait 3-4 weeks for blood levels to build up. Within 3-5 days, you’re already feeling increased energy, improved libido, and better training performance. By week 2, muscle growth and strength gains are in full effect.
The short ester means you need to inject every other day or daily to maintain stable blood levels. While this is more frequent than long esters, it gives you incredible control – you can start and stop quickly, adjust doses easily, and clear your system rapidly when needed.
The Main Benefits For You
Immediate Results
Unlike Testosterone Enanthate or Cypionate that take 3-4 weeks to fully kick in, Test Prop starts working within 24-48 hours. Your energy increases immediately. Your libido improves within days. Strength gains start by week 1-2. You don’t waste weeks waiting for long esters to saturate.
Zero Water Retention
Test Prop causes significantly less water bloat than long-ester testosterone. Your muscles look full but hard and defined. You don’t wake up puffy. This makes it perfect for cutting cycles and contest prep when you need to stay lean and vascular.
Perfect for Contest Prep
Professional bodybuilders use Test Prop for the final 8-12 weeks before competitions. It provides all the benefits of testosterone – strength, muscle preservation, energy, libido – without the excessive water retention that ruins your conditioning.
Flexible Dosing Control
The short ester gives you precise control. If you experience side effects, stopping provides relief within 3-4 days as it clears your system. If you need to adjust your dose, changes take effect within days instead of weeks. This flexibility is valuable for experienced users.
Fast PCT Initiation
When your cycle ends, Test Prop clears in just 3-4 days instead of 2-3 weeks like Enanthate/Cypionate. You can start PCT much sooner, which means less muscle loss in the gap between cycle end and testosterone recovery. This is a major practical advantage.
Superior for Shorter Cycles
While long esters require 12-16 week cycles minimum, Test Prop 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.
Pairs Perfectly with Short Esters
If you’re running Trenbolone Acetate, NPP, or Masteron Propionate, Test Prop aligns injection schedules perfectly. All compounds have similar half-lives, so you inject everything on the same days. This makes complex stacks much more convenient.
FDA DISCLAIMER: This product isn’t intended to diagnose, treat, cure, or prevent any disease. Testosterone Propionate is a controlled substance and should only be used under proper medical supervision for legitimate medical purposes.
Recommended Dosage for Male:
300-700mg per week split into frequent injections. Beginners start with 300-400mg weekly. Intermediate users run 400-500mg weekly. Advanced users go to 600-700mg weekly. Due to short ester, split weekly dose into injections every other day (EOD) or daily.
Injection Schedule Examples:
For 400mg weekly: Inject 100mg Monday, Wednesday, Friday, Sunday (repeating pattern).
Or: Inject 57mg daily (0.57ml).
The key is maintaining stable blood levels with frequent injections due to 1-1.5 day half-life.
Recommended Dosage for Female:
NOT recommended. Testosterone causes severe, permanent masculine side effects in women that don't reverse after stopping.
When to Inject:
Inject into glutes, thighs, or shoulders using 1-inch needle. Due to frequent injections, rotate sites religiously to prevent scar tissue. Many users follow rotation patterns: Monday glutes, Tuesday thighs, Wednesday shoulders, Thursday glutes, Friday thighs, Saturday shoulders, Sunday glutes.
Cycle Duration:
8-12 weeks is optimal for Test Prop. The short ester allows effective shorter cycles. Can run up to 16 weeks but most users prefer 8-12 weeks for balance between results and side effect management.
Stacking:
Test Prop stacks perfectly with other short esters. Cutting stack: 400mg Test Prop weekly + 350mg Trenbolone Acetate weekly + 400mg Masteron Propionate weekly. Lean bulk: 500mg Test Prop weekly + 400mg NPP weekly. Add oral like Anavar or Winstrol final 6 weeks for extreme definition.
Post Cycle Therapy (PCT):
Required after cycle ends. Test Prop clears rapidly - wait only 3-4 days after last injection, then start PCT: Nolvadex 40/40/20/20mg daily + Clomid 50/50/25/25mg daily for 4 weeks. This restarts natural testosterone production.
Important Timing:
Test Prop reaches peak blood levels within 24-36 hours. Full saturation occurs by day 3-5. You'll notice effects immediately - within the first week. Maximum gains continue building throughout your 8-12 week cycle.
Most Common:
- Complete testosterone suppression during cycle
- Minimal water retention (much less than Enanthate/Cypionate)
- Frequent injections required - EOD or daily dosing
- Acne on back, chest, shoulders
- Oily skin
- Gyno risk if estrogen not controlled (need Arimidex)
- Testicular atrophy during cycle (reverses with PCT)
- Hair loss acceleration if genetically predisposed
- More post-injection pain (PIP) than long esters initially
Less Common:
- Elevated blood pressure from androgens
- Negative cholesterol impact (HDL drops, LDL rises)
- Mood changes - increased aggression or confidence
- Sleep quality changes
- Increased red blood cell count
How to Manage:
Use Arimidex 0.5mg every other day for estrogen control. Rotate injection sites meticulously. Warm vial before drawing to reduce PIP. Massage injection sites after injecting. Get blood work at week 4-6 to check testosterone, estradiol, cholesterol. Do cardio 3-4x weekly. Monitor blood pressure weekly.
Post-Injection Pain Note:
Test Prop can cause more PIP than long esters, especially first 2-3 weeks. This is normal with propionate ester. Pain typically decreases as your body adapts. Using proper injection technique and rotating sites helps significantly.
Active Ingredient:
Testosterone Propionate (Testosterone 17β-propionate)
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 FDA-approved use: Treating male hypogonadism (historically - rarely prescribed currently due to frequent injection requirement).
Primary bodybuilding use: Cutting cycles, contest preparation, shorter cycles, stacking with other short esters, athletes who prefer fast-acting compounds.
Classification:
Androgen, anabolic steroid, short-acting androgen ester
Mechanism of Action:
Testosterone Propionate is testosterone attached to a propionate ester. After injection, esterase enzymes rapidly cleave the propionate ester, releasing free testosterone. Testosterone binds to androgen receptors in muscle tissue, dramatically increasing protein synthesis and nitrogen retention. Enhances glycogen storage, increases IGF-1, inhibits cortisol, promotes erythropoietin production.
Half-Life:
Approximately 1-1.5 days (20-36 hours) - requires EOD or daily injections
Time to Peak Concentration:
Approximately 12-24 hours after intramuscular injection
Active Life:
3-4 days after injection
Detection Time:
2-3 weeks after last injection in standard drug testing (much shorter than long esters)
Bioavailability:
High (oil-based intramuscular injection provides excellent absorption)
Anabolic/Androgenic Ratio:
100:100 (testosterone is the baseline standard)
Aromatization:
Moderate - Converts to estrogen via aromatase enzyme. Despite less water retention than long esters, still requires AI at moderate-high doses.
DHT Conversion:
Converts to dihydrotestosterone (DHT) via 5α-reductase enzyme
Molecular Formula:
C22H32O3
Molecular Weight:
344.49 g/mol
Chemical Name:
Androst-4-en-3-one, 17-[(1-oxopropoxy)]-, (17β)-
Administration:
Deep intramuscular injection into glutes, thighs, or deltoids. Use 1-1.5 inch needle. Inject slowly over 20-30 seconds. Rotate sites with every injection due to 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.
