British Dragon Sustabol 350 Testosterone Blend 10 ml Vial

It is a four-ester testosterone blend at 350 mg per ml in a 10 ml multi-dose vial. The declared esters are testosterone propionate, phenylpropionate, isocaproate and decanoate. The total concentration and the ester names come from the product label, but the per-ml split of each ester is not published, so this page does not put a milligram figure on any single arm of the mix.

Each ester releases the same hormone at a different speed. Propionate frees testosterone within about two days, which is why the blend is felt early; phenylpropionate and isocaproate sit between the extremes; decanoate releases over roughly five to eight days and carries the tail. With no single half-life for the mixture, the practical rule is that the level stays covered between twice-weekly shots rather than swinging on each injection.

Two injections a week is the usual arrangement, into the gluteal or deltoid muscle with the sites rotated to avoid repeated trauma to one spot. A once-weekly schedule is possible because of the decanoate arm, but splitting the dose keeps the level steadier. There is no approved schedule for this product, since it is not a registered medicine, so the frequency here follows how the esters behave rather than a label.

Water retention and raised blood pressure are the common reports, along with acne and oily skin. Gynecomastia can appear when estradiol runs unchecked, and longer runs have been linked to a rising haematocrit. Natural testosterone production is suppressed, which can shrink the testes and affect fertility, usually reversible after recovery. Blood counts, lipids and estradiol are the standard monitoring set, and any of these signs calls for medical advice.

Yes, because the blend shuts down the body's own production at any effective dose. The usual recovery is tamoxifen 20 mg daily for four weeks, with clomiphene as the alternative. Timing is set by the longest ester: decanoate needs roughly two weeks to clear before the SERM starts, otherwise the run stays suppressed. Blood work about six weeks later confirms luteinising hormone, follicle-stimulating hormone and total testosterone.
