SP Supertest

What Is SP Supertest?

SP Supertest from SP Laboratories is an injectable blend supplied as a 10 ml vial at 450 mg/ml. It contains five testosterone esters rather than one, which makes it the most concentrated and most layered testosterone product in this category.

The name describes what it is: a testosterone mix. What makes it unusual is how many esters went into it, and how unevenly they are weighted.

Five Esters, Unevenly Weighted

The vial carries 450 mg in total, and the split is not even. The decanoate makes up roughly a third of it on its own, which gives the blend a much longer tail than the four ester mixes sold beside it.

• Testosterone Decanoate, 147 mg/ml - the heaviest share, and one of the longest testosterone esters used.
• Testosterone Cypionate, 125 mg/ml - the second largest, a slow release on its own.
• Testosterone Propionate, 73 mg/ml - the fast ester, available first.
• Testosterone Phenylpropionate, 73 mg/ml - a shorter ester bridging propionate and the slows.
• Testosterone Acetate, 32 mg/ml - the smallest share, and the quickest of the five.

Added together the five esters total 450 mg/ml. Because the weight sits on decanoate and cypionate, this blend behaves more like a long ester product than the presence of acetate and propionate would suggest.

What To Know Before You Buy

Every ester in the vial is testosterone, so the core considerations do not change with the blend: it suppresses natural production and it converts to estradiol, and neither depends on which ester is attached. What the mix changes is the shape of the release, and the weighting matters here. With two thirds of the dose on decanoate and cypionate, levels do not fall away when the vial is put down, and the tail after the last administration is longer than the ester count alone implies.
