Sustabol 350 - British Dragon

Buy Sustabol 350 by British Dragon at XSteroids. Sustabol is a four-ester testosterone blend at 350 mg/mL in a 10 mL vial. Same hormone in every ester, four different release speeds, and a schedule that keeps the level steady instead of spiking and sagging.

Testosterone is a prescription medicine everywhere; sold here it is a research product and the notes below are educational.

What Sustabol 350 Is

The brand lists the composition per millilitre as propionate 42 mg, phenylpropionate 84 mg, isocaproate 84 mg and decanoate 140 mg, which adds up to exactly 350 mg/mL. Two of those are short - propionate clears in roughly two days - and two are long, with decanoate carrying the level between injections.

The proportions are worth comparing with something familiar. The clinical four-ester product used in medicine contains 30, 60, 60 and 100 mg of the same esters. Sustabol 350 is that same formula scaled by about 1.4, which is exactly what the numbers show: 42, 84, 84, 140.

What the Vial Gives You

The vial holds 10 mL, so 3500 mg of testosterone across the four esters. At 350 mg a week that is 10 weeks of supply; 500 mg gives seven weeks; 700 mg five weeks. One millilitre is 350 mg and a half millilitre is 175 mg, so two half-millilitre injections a week land on the 350 mg weekly dose.

Sustabol Dosage and Schedule

The brand gives 350 to 700 mg per week split into at least two injections - Monday and Thursday is the example - and adds that every other day is the better pattern for balancing fast and slow esters. Cycles run 10 to 14 weeks.

It is usable as a first cycle, though the brand itself suggests a single-ester testosterone such as Testabol Enanthate 250 for a beginner. Anyone taking the blend for the first time should plan two injections a week and keep an aromatase inhibitor on hand rather than waiting for symptoms.

Sustabol vs Andropen

The other blend in the line is Andropen 450, and the difference is structural: four esters at 350 mg/mL against five at 450 mg/mL. Andropen adds acetate for a quicker onset and swaps isocaproate for cypionate, which lengthens the tail and lets the injections run less often. Sustabol is the lower-concentration, more classical option and the easier one to control week to week.

Stacking Sustabol 350

In a mass phase it pairs with Decabol and an oral kickstart from Methanabol for the first weeks. In a leaner phase the partner is Trenabol, with the dose of the blend kept moderate because aromatisation is high either way.

Estrogen Control and PCT

Because it aromatises, water retention, raised blood pressure and gynecomastia are the risks, and an aromatase inhibitor such as Letrobol is the usual tool. The brand notes that blood pressure is worth watching on cycle, which is a blood pressure monitor question rather than a pill question.

The blend is highly suppressive, so PCT follows the cycle as a matter of course. The brand's gold standard is a combination of Tamoxifen and Clomiphene, with blood work to confirm that the axis has actually restarted rather than assuming it.

Side Effects

Estrogenic effects are water retention, gynecomastia and blood pressure rise. Androgenic effects are acne, oily skin, accelerated hair loss in those predisposed, and increased body and facial hair. Natural testosterone production is strongly suppressed, and both red blood cell count and cholesterol are worth monitoring over a 10 to 14 week cycle. There is no direct liver toxicity: the product is not a 17-alpha-alkylated oral, so the risk profile here is hormonal and cardiovascular.

Storage

Store the vial at room temperature, away from direct light, and out of the reach of children. Do not use a solution that shows particles or discolouration.
