Sustaxyl 350 mg Detailed

Sustaxyl 350 by Kalpa Pharmaceuticals – Potent Sustanon-Style Blend

Sustaxyl 350 is an advanced injectable testosterone blend manufactured by Kalpa Pharmaceuticals. This compound contains four testosterone esters for rapid onset and long-lasting hormonal support:

Testosterone Propionate – 42 mg
Testosterone Phenylpropionate – 84 mg
Testosterone Isocaproate – 84 mg
Testosterone Decanoate – 140 mg

With a total strength of 350 mg/mL, this mix mimics the well-known Sustanon profile, offering fast-acting and extended testosterone release. Ideal for bulking, Sustaxyl delivers powerful anabolic and androgenic effects to maximize muscle gain, recovery, and strength.

Why Choose Sustaxyl Over Single-Ester Testosterone?

Each ester in Sustaxyl activates at different times, resulting in steady blood levels. Propionate works within 24–48 hours, while decanoate sustains testosterone levels for up to 3–4 weeks. This makes Sustaxyl a more stable option than Testoxyl Enanthate or Testoxyl Cypionate.

Studies from the National Institutes of Health confirm that mixed-ester testosterone formulations can improve compliance and reduce injection frequency for TRT and bodybuilding use.

Typical Sustaxyl Cycle (12 Weeks)

Weeks 1–12: Sustaxyl 350 – 500–750 mg/week (1.5–2 mL/week)
Weeks 1–6: Dianoxyl 10 – 30 mg/day
Weeks 1–12: Nandroxyl – 400 mg/week
Anti-Estrogen: Arimixyl – 0.5 mg every other day

Post Cycle Therapy (PCT)

PCT begins 2–3 weeks after the last Sustaxyl injection:

Clomixyl: 50 mg/day for 3 weeks
Nolvaxyl: 20 mg/day for 3 weeks

Stacking and Compatibility

Sustaxyl stacks well with classic bulking agents such as Dianoxyl, Nandroxyl, and even long-acting esters like Boldenoxyl.

Some users compare its long-acting effects to other high-dose testosterone formulations, but Sustaxyl's multi-ester profile provides better peak-and-sustain balance.

Recommended Dosage & Injection Tips

Beginner dose: 350–500 mg/week
Intermediate: 750 mg/week (split into 2 injections)
Injection sites: Gluteus, quadriceps, deltoids

Side Effects and Considerations

As with all testosterone-based compounds, Sustaxyl may cause estrogenic side effects such as water retention, gynecomastia, and oily skin. To mitigate these, include anti-estrogens like Arimixyl during the cycle. Monitor cholesterol, blood pressure, and hormone levels regularly.

Conclusion

Sustaxyl 350 is a top-tier blend designed for users seeking consistent testosterone levels, enhanced anabolic activity, and reliable mass gains. Manufactured by Kalpa Pharmaceuticals, it offers a professional-grade solution for athletes who value performance and convenience.

I have been using this for my cruise for about 6 months now. Aside from real true human grade test, I think this is one of the best UGL sust's available.

Once the product arrived I added it to my current cycle which was 100mg Test Prop every other day from another supplier. I wanted to increase my test dosage so I would do 350mg of sus and 50mg of prop every other day. I noticed within a weak that my libido was going crazy through the roof. I had constant boners that almost became problematic lol. But overall this stuff is great. It's thin clear and smooth pinning without too much pip. My skin became oilier and I had that alpha male aggression. Recovery time increased from gym sessions and I could tell this product definitely added the boost I needed.

1.3ml per week you dont feel toouch pip bit I have access to Lidocaine 5% patches hehe so those help with any pip. My arms feel strong and after 2 weeks it was noticeable, some acne LARGE pumps that almost hurt (thank God for muscle relaxers) new veins came in, my nurse had to run down to the er to get a LEG CUFF to take my blood pressure with because the others wouldn't fit lol. Noticing some fat loss so all in all pretty happy thus far!
