Buy Sustanon online
Sustanon is not a single chemical substance with a unique CAS number, but rather a blend of four distinct testosterone esters formulated as an oil-based injectable solution. Because it is a mixture, “Sustanon powder” typically refers to buying or blending the individual raw ester powders used to make the compound. [1, 2]
Description
Sustanon (most commonly known as Sustanon 250) is an injectable androgen and anabolic steroid blend. In its standard medical formulation (per 1 mL ampoule), it consists of:
- Testosterone Propionate (30 mg) – CAS No. 57-85-2
- Testosterone Phenylpropionate (60 mg) – CAS No. 1255-49-8
- Testosterone Isocaproate (60 mg) – CAS No. 4170-67-0 (or related ester identifiers)
- Testosterone Decanoate (100 mg) – CAS No. 5721-91-5
The combination of fast- and slow-acting esters provides both an immediate rise in testosterone levels and a sustained release over several weeks.

Had many good orders of this company and their products work. Ok a few delays with my orders but I received everything I paid for! I do use other companies also but what I will say is these products seem superior
