Buy Test 400 — For Sale at Roids101 Canada
Buy Test 400 online from Roids101 — a high-concentration test 400 steroid blend dosed at 400mg/mL in a 10 mL vial. That’s 4,000mg of total testosterone per vial — Testosterone Propionate, Testosterone Enanthate, and Testosterone Cypionate combined into one shot.
The appeal of Test 400 is dead simple: more testosterone per mL means fewer injections and less oil volume per pin. If you’re running a high-dose test cycle, this blend cuts your injection volume nearly in half compared to standard 250mg/mL vials. Now for sale at Roids101 — shipped discreet anywhere in Canada.
What Is Test 400?
Test 400 is an injectable testosterone blend containing three different testosterone esters at a total concentration of 400mg/mL. Think of it as Sustanon’s bigger, more concentrated cousin — same concept (multiple esters, staggered release), but packed into a much higher concentration per mL.
The blend is built for experienced users running moderate to high-dose testosterone cycles who want to reduce injection volume without reducing their dose.
Testosterone Propionate — 50mg/mL
Test Prop is the short ester in this blend. Active half-life sits at ~2-3 days. It hits your bloodstream first — you’ll feel the initial testosterone surge within the first few days of your cycle. It also clears the fastest, which is useful for early estrogen management and getting the compound working before the longer esters fully saturate.
Testosterone Enanthate — 175mg/mL
Test E is the backbone of most steroid cycles worldwide — and for good reason. Active half-life of ~7-10 days. This medium-to-long ester provides the steady, sustained testosterone release that carries your cycle week after week. It’s the reason you only need to pin twice a week instead of daily.
Testosterone Cypionate — 175mg/mL
Test C is nearly identical to Test E in practice. Half-life of ~8-12 days — marginally longer. The two esters overlap so closely that they’re pretty much interchangeable. Having both in the blend extends the release curve slightly, giving you some of the most stable blood levels possible between injections.
Test 400 Benefits
| Benefit | What It Means for You |
|---|---|
| 400mg per mL | Nearly double the concentration of standard test vials (250mg/mL). Less oil volume per injection, fewer mL needed per week to hit your target dose. |
| Three-ester release curve | Test Prop kicks in within days, Test E carries the middle, Test C extends the tail. More stable blood levels than any single ester alone. |
| Fewer injections at high doses | Running 800mg/week? That’s 2 mL total — 1 mL twice a week. With standard 250mg/mL, you’d need 3.2 mL spread across multiple pins. |
| Versatile for bulk or recomp | Testosterone is the foundation compound. Use Test 400 as your base and stack whatever you want on top — Deca for mass, Masteron for hardness, Anavar for lean gains. |
| One vial goes further | 4,000mg total per 10 mL vial. At 400-800mg/week, one vial lasts 5-10 weeks depending on your dose. |
| Cost-effective for high-dose cycles | $140 for 4,000mg of testosterone. That’s $0.035 per mg — compare that to buying multiple vials of single-ester test to reach the same total. |

| Testosterone Cypionate | 175mg/mL | ~8-12 days | Extended tail — smooths out the release curve between pins |
Test 400 Dosage and Cycle Protocol
Inject twice per week — Monday and Thursday, or whatever split fits your schedule. The combination of long esters (Test E + Test C) makes twice-weekly pinning sufficient for stable blood levels. The Prop component front-loads each injection slightly, so you feel it working sooner.
Recommended Cycle Protocol
| Experience Level | Weekly Dose | Injection Volume | Cycle Length |
|---|---|---|---|
| Intermediate | 400-600mg/week | 0.5-0.75 mL per pin, 2x/week | 12-16 weeks |
| Advanced | 600-800mg/week | 0.75-1 mL per pin, 2x/week | 12-16 weeks |
Note: this is a high-concentration blend. If you’re running your first testosterone cycle, standard 250mg/mL Test E or Test C is the smarter starting point. Test 400 is built for users who already know their dose and want to reduce oil volume.
Post-Injection Pain (PIP)
Here’s the trade-off with high-concentration gear — PIP can hit hard. Cramming 400mg of hormone into a single mL of oil requires more solvents (typically benzyl alcohol and benzyl benzoate at higher percentages). Some users feel significant soreness at the injection site for 24-72 hours.
Tips to reduce PIP: inject slowly, warm the vial in your hands or under warm water beforehand, rotate injection sites religiously, and use a heating pad on the area after pinning. If PIP is unbearable, you can cut Test 400 with sterile oil to bring the effective concentration down.
On-Cycle Support
| Support Compound | Why You Need It | Dose |
|---|---|---|
| Aromatase Inhibitor (AI) | Testosterone aromatizes — higher doses mean more estrogen conversion | Arimidex 0.5mg EOD, adjust based on bloodwork |
| HCG (optional but recommended) | Prevents testicular atrophy during long cycles | HCG 250-500 IU twice/week |
Test 400 vs Sustanon vs Single-Ester Testosterone
Three ways to run testosterone. Same hormone, different delivery systems. Here’s how they stack up in practice.
| Factor | Test 400 | Sustanon 250 | Test E or Test C (250mg/mL) |
|---|---|---|---|
| Concentration | 400mg/mL | 250mg/mL | 250mg/mL |
| Number of esters | 3 (Prop + E + C) | 4 (Prop + PP + Isocaproate + Decanoate) | 1 |
| Injection frequency | 2x/week | 2x/week (for stable levels) | 2x/week |
| PIP potential | Higher — concentrated formula needs more solvents | Moderate | Low — standard concentration |
| Oil volume per 500mg | 1.25 mL | 2 mL | 2 mL |
| Price per mg | $0.035/mg ($140 / 4,000mg) | Varies | Varies |
| Ideal for | High-dose cycles, reducing injection volume | Users who want staggered ester release at standard concentration | Users who want simple, proven, low-PIP testosterone |
Bottom line: Test 400 shines when you’re running 400mg/week or above and you want to minimize injection volume. If PIP bothers you or you’re running lower doses, single-ester test at 250mg/mL is the smoother and more practical choice.
Stacking Test 400 — What to Add
Testosterone is the foundation compound — everything stacks on top of it. Test 400 makes it efficient to hit your test dose, leaving room to add whatever matches your goal.
Bulking Stack
Test 400 at 600-800mg/week + Deca at 300-400mg/week for 12-16 weeks. Add Dbol at 30-50mg/day for the first 4-6 weeks as a kickstart. Classic mass builder — the stack that’s been putting size on bodybuilders for decades.
Lean Bulk / Recomp Stack
Test 400 at 400-600mg/week + Anavar at 40-60mg/day. Lean gains without the water. Anavar’s mild profile complements the test base without adding the bloat that comes with heavier compounds.
Strength Stack
Test 400 at 600mg/week + Anadrol at 50-100mg/day for 4-6 weeks. Raw strength and rapid weight gain. Liver support is mandatory with Anadrol — run NAC and TUDCA throughout.
Test 400 Side Effects and How to Manage Them
Testosterone is the hormone your body already produces — so the sides come from having supraphysiological levels of it, plus the estrogen it converts into. Here’s the full rundown.
| Side Effect | Cause | Management |
|---|---|---|
| Post-injection pain (PIP) | High concentration (400mg/mL) requires more solvents in the carrier oil | Inject slowly, warm the oil, rotate sites, heat pad after pinning. Dilute with sterile oil if needed. |
| Estrogen elevation | Testosterone aromatizes to estradiol via the aromatase enzyme | Arimidex 0.5mg EOD. Get bloodwork — don’t crash your estrogen by overdoing the AI. |
| Water retention / bloat | Elevated estrogen causes subcutaneous water retention | Proper AI dosing and moderate sodium intake. Some bloat is expected on high-dose test — it comes with the territory. |
| Gynecomastia | Estrogen binding at breast tissue receptors | AI for prevention. If symptoms appear mid-cycle, add Nolvadex at 20-40mg/day. |
| Acne | Androgenic — increased sebum production from elevated DHT | Shower after training, benzoyl peroxide wash. Accutane for severe cases. |
| Hair loss | DHT conversion — if you’re genetically predisposed | Finasteride 1mg/day can slow it. If you’re not prone, this isn’t a concern. |
| Testosterone suppression | Exogenous testosterone shuts down your HPTA | Full PCT required. Start Nolvadex 2 weeks after last injection — the long esters (Test E, Test C) need time to clear. |
Where to Buy Test 400 in Canada
High-concentration testosterone demands precise manufacturing. If the actual concentration is 350mg/mL instead of the labeled 400mg/mL, your entire cycle math is off — and you won’t realize it until bloodwork comes back lower than expected.
Test 400 by Apoxar delivers the labeled 400mg/mL. Roids101 ships it discreet, with tracking, anywhere in Canada.

Who Should Use Test 400?
| User Type | Why Test 400 |
|---|---|
| Experienced users on high-dose cycles | Running 500-800mg/week? Test 400 cuts your injection volume nearly in half. Less oil, fewer syringes, same dose. |
| Cost-conscious users | $140 for 4,000mg of test. At 500mg/week, one vial lasts 8 weeks. That’s $17.50 per week of testosterone. |
| Multi-compound stackers | Adding Deca, EQ, Tren, or orals on top? Test 400 keeps your test base low-volume so you’re not injecting 4+ mL per session across multiple compounds. |
| Users who don’t mind PIP | The higher concentration means more post-injection soreness. If you’ve dealt with it before and don’t care, Test 400 is the efficient choice. |
Who Should NOT Use Test 400
| User Type | Why Not |
|---|---|
| First-cycle users | Start with Test E or Test C at 250mg/mL. Lower concentration = smoother injections, less PIP, easier to dose at beginner levels (300-500mg/week). |
| PIP-sensitive users | If post-injection pain derails your training or makes you dread injection day, stick with 250mg/mL testosterone. Night and day difference in comfort. |
| Low-dose TRT users | At 100-200mg/week, you’re injecting tiny fractions of a mL. Accurate dosing is tough at those volumes — standard concentration makes more sense. |
Frequently Asked Questions
What is Test 400?
Test 400 is a high-concentration testosterone blend containing Testosterone Propionate (50mg), Testosterone Enanthate (175mg), and Testosterone Cypionate (175mg) per mL — totaling 400mg/mL. It’s designed for experienced users who want more testosterone per injection with less oil volume.
How often should I inject Test 400?
Twice per week. The long-ester components (Test E and Test C) make twice-weekly pinning enough for stable blood levels. Monday and Thursday is a common split.
Does Test 400 cause more PIP than regular testosterone?
Yes. Higher concentration requires more solvents in the carrier oil, which can cause post-injection soreness lasting 24-72 hours. Inject slowly, warm the oil first, and rotate injection sites. You can dilute with sterile oil if the PIP is too much.
Test 400 vs Sustanon — what’s the difference?
Both are testosterone blends with multiple esters. Sustanon is dosed at 250mg/mL with four esters. Test 400 runs at 400mg/mL with three esters. The main practical difference: Test 400 needs less injection volume to reach the same weekly dose.
Do I need an AI with Test 400?
Yes. Testosterone aromatizes into estrogen — and at doses of 400mg/week or above, aromatization picks up significantly. Run Arimidex at 0.5mg EOD and adjust based on bloodwork. Don’t crash your estrogen — that’s worse than running it slightly elevated.
What’s the right Test 400 dosage?
Intermediate users: 400-600mg/week. Advanced users: 600-800mg/week. Cycle length: 12-16 weeks. This is not a first-cycle compound — use standard 250mg/mL testosterone if you’re new to gear.
How much does Test 400 cost?
$140 CAD for a 10 mL vial at 400mg/mL. That’s 4,000mg of total testosterone. At 500mg/week, one vial lasts 8 weeks — about $17.50 per week.
What PCT do I need after a Test 400 cycle?
Full PCT with Nolvadex: 40mg/day for weeks 1-2, then 20mg/day for weeks 3-4. Start PCT 2 weeks after your last injection — the long esters (Test E and Test C) need time to clear your system before the SERM kicks in.
Can I use Test 400 for my first cycle?
Not recommended. The high concentration causes more PIP, and beginners need lower doses (300-500mg/week) where standard 250mg/mL test is easier to measure and smoother to inject. Start with Test E or Test C — graduate to Test 400 when you know your body and your dose.
What should I stack with Test 400?
Bulking: add Deca at 300-400mg/week or Dbol at 30-50mg/day as a kickstart. Lean gains: add Anavar at 40-60mg/day. Test 400 serves as the foundation — stack based on whether you’re chasing mass, strength, or a recomp.
