What Is Alpha North Test 400?
Alpha North Test 400 is a high-concentration testosterone blend dosed at 400mg/mL in a 10mL multi-use vial. That is 60% more testosterone per millilitre than a standard 250mg/mL product, which means you inject less oil to reach the same total weekly amount. For users running higher testosterone protocols, this translates directly into fewer millilitres drawn, smaller injection volumes, and less total oil deposited into the muscle each week.
We formulate Alpha North Test 400 in HPLC-grade grape seed oil, batch-verify every vial, and seal it in tamper-evident packaging with a printed lot number. Order now from Alpha North Labs Canada with tracked delivery to every province and territory.

The Math: Why 400mg/mL Saves You Volume and Money
This is the core reason to buy Test 400 over a standard 250mg/mL product. The table below shows exactly how much oil you need to inject at common weekly testosterone amounts:
| Weekly Amount | Test 250mg/mL (Volume Needed) | Alpha North Test 400 (Volume Needed) | Oil Saved Per Week |
|---|---|---|---|
| 400mg | 1.6mL | 1.0mL | 0.6mL less |
| 500mg | 2.0mL | 1.25mL | 0.75mL less |
| 600mg | 2.4mL | 1.5mL | 0.9mL less |
| 800mg | 3.2mL | 2.0mL | 1.2mL less |
Less oil per injection means smaller injection volumes, less post-injection discomfort, and more flexibility with injection site rotation. It also means each 10mL vial of Alpha North Test 400 contains 4,000mg of total testosterone, compared to 2,500mg in a standard 250mg/mL vial. You get significantly more product per vial, which translates to better value per milligram of testosterone.
Who Should Buy Test 400?
Alpha North Test 400 is not for everyone. If you are running a low-to-moderate testosterone protocol at 250mg per week, a standard Testosterone Enanthate or Testosterone Cypionate vial will serve you just fine and last longer at that amount. Test 400 earns its place in higher-amount protocols where the volume advantage becomes meaningful.
Experienced Users Running 400mg+ Per Week
If your weekly testosterone sits at 400mg or above, Test 400 lets you reach that amount in a single 1mL injection. At 500mg per week, you only need 1.25mL. Compare that to 2mL of a 250mg/mL product. The volume difference adds up across a 12-to-16-week cycle.
Users Who Want Fewer Vials Per Cycle
A single vial of Alpha North Test 400 holds 4,000mg of testosterone. A 12-week cycle at 500mg per week requires 6,000mg total, meaning you need just two vials of Test 400 to complete the entire cycle. That same protocol would require three vials of a 250mg/mL product.
Users Stacking Multiple Injectables
When you are injecting testosterone alongside compounds like Deca Durabolin, Equipoise, or Trenbolone Enanthate, the total oil volume per injection session climbs quickly. Using Test 400 for your testosterone base reduces the testosterone portion of that volume, keeping total injection volume manageable.
Addressing Post-Injection Discomfort
High-concentration testosterone products carry a reputation for increased post-injection pain (PIP). Research published in the journal Clinical Endocrinology confirms that carrier oil composition is one of the key factors influencing injection site discomfort. This is why our choice of carrier oil matters more in a 400mg/mL product than in a standard 250mg/mL formulation.
We formulate Alpha North Test 400 in HPLC-grade grape seed oil specifically because it is thinner and smoother than the cottonseed or castor oil carriers used by many other sources. Grape seed oil flows through fine-gauge needles more easily and disperses into muscle tissue with less resistance, which directly reduces post-injection irritation. Additionally, warming the vial to body temperature before drawing and injecting slowly over 15 to 20 seconds further minimizes discomfort.
Common Stacking Options
Alpha North Test 400 serves as the testosterone base in any stack. A landmark study published in the New England Journal of Medicine demonstrated that testosterone increases fat-free mass and strength regardless of ester or formulation. Test 400 delivers the same testosterone as any single-ester product, just in a higher concentration per mL.
Bulking
Pair Alpha North Test 400 with Deca Durabolin for size and joint support, or add Dianabol as an oral kick-start. The volume advantage of Test 400 keeps your injection sessions shorter when stacking multiple compounds.
Cutting
During a deficit, pair it with Anavar for lean tissue preservation or Masteron Enanthate for a drier, harder appearance. Add Clenbuterol or T3 to accelerate fat loss.
Strength
For raw strength, Test 400 with Anadrol is one of the most aggressive combinations we see our customers run. Add an aromatase inhibitor like Aromasin to manage estrogen and you have a complete strength protocol.
How Alpha North Test 400 Compares to Our Other Testosterone Products
| Product | Concentration | Total mg Per 10mL Vial | Best For |
|---|---|---|---|
| Test 400 | 400mg/mL | 4,000mg | High-amount protocols, reduced injection volume, better value per mg |
| TNT 400 | 400mg/mL | 4,000mg (test + tren) | Combined testosterone and trenbolone in one vial |
| Sustanon 250 | 250mg/mL | 2,500mg | Four-ester staggered release, fast onset + extended duration |
| Test Enanthate | 250mg/mL | 2,500mg | All-purpose, beginner cycles, simplest protocol |
| Test Cypionate | 250mg/mL | 2,500mg | TRT, weekly protocols, longest single-ester half-life |
Side Effects and How to Manage Them
Test 400 carries the same side effect profile as any testosterone product. Higher weekly amounts increase the likelihood of estrogen-related effects, so aromatase inhibitor management is especially important. We stock everything you need.
Estrogen Management
We carry Aromasin, Arimidex, and Letrozole. Have your AI on hand and ready before you start your first injection of Test 400.
Androgenic Effects
We offer Finasteride for hair loss prevention and Accutane for persistent acne.
PCT
Post-cycle therapy is mandatory after any testosterone cycle. Plan 2 to 3 weeks of clearance after your last Test 400 injection before starting Nolvadex and Clomid. Running HCG during the cycle keeps testicular function intact for a faster recovery.
Storage and Handling
Store Alpha North Test 400 at controlled room temperature between 15 and 25 degrees Celsius. Keep the vial away from direct light and heat. Do not freeze. High-concentration products may sometimes appear slightly thicker than standard formulations. If this occurs, warm the vial briefly under warm running water or hold it in your hands for a minute before drawing. This is normal and does not affect potency.

Frequently Asked Questions About Alpha North Test 400
What is Test 400?
Test 400 is a high-concentration testosterone blend dosed at 400mg per mL. It delivers 60% more testosterone per millilitre than a standard 250mg/mL product, meaning you inject less oil to reach your target weekly amount.
How is Test 400 different from Sustanon 250?
Both are testosterone blends, but they serve different purposes. Sustanon 250 is designed for staggered ester release, giving you fast onset from short esters and sustained levels from long esters. Test 400 is designed for concentration, giving you more testosterone per mL to reduce injection volume. If your goal is pharmacokinetic variety, choose Sustanon. If your goal is less oil per injection, choose Test 400.
Does Test 400 cause more post-injection pain?
High-concentration products can cause more post-injection discomfort than standard formulations. We reduce this by formulating in HPLC-grade grape seed oil, which is thinner and smoother than cottonseed or castor oil. Warming the vial to body temperature and injecting slowly also helps. Most of our customers who switch to Alpha North Test 400 from other brands report noticeably less PIP because of our carrier oil choice.
Is Test 400 good for beginners?
Test 400 is better suited for experienced users running 400mg or more per week. If you are new and starting at 250 to 300mg per week, a standard Testosterone Enanthate or Testosterone Cypionate product is easier to measure accurately and more practical at lower amounts.
How many vials do I need for a full cycle?
Each vial contains 4,000mg of total testosterone. At 500mg per week for 12 weeks, you need 6,000mg total, so two vials cover your entire cycle. At 400mg per week for 12 weeks, a single vial (4,000mg) and a small portion of a second covers you. Compare that to needing three vials of a 250mg/mL product for the same protocol.
Can I stack Test 400 with other compounds?
Yes. Test 400 works as the testosterone base in any stack. Common bulking combinations include Test 400 with Deca Durabolin or Dianabol. For cutting, pair it with Anavar or Masteron. The high concentration keeps your testosterone injection volume small, which is especially helpful when stacking multiple injectables.
How often do I inject Test 400?
Once or twice per week. Splitting your weekly amount into two injections produces smoother blood levels and can further reduce post-injection discomfort by keeping each individual injection volume smaller.
What carrier oil do you use?
We formulate Alpha North Test 400 in HPLC-grade grape seed oil. This is critical in a high-concentration product because carrier oil quality directly affects post-injection comfort. Grape seed oil is thinner than cottonseed or castor oil, passes through fine-gauge needles easily, and disperses into muscle tissue smoothly.
Do you offer tracked shipping?
Yes. Every order ships with tracked delivery in plain, discreet packaging to all provinces and territories in Canada. Pay with crypto and save 15% on your order.
