OmniMass by Xeno Labs arrives as a 10 ml vial holding nandrolone decanoate, testosterone enanthate, and boldenone undecylenate at a combined 500 mg per ml. Each compound contributes to the total concentration, with all three esters sharing the same injectable solution. Xeno Labs, based in the USA and producing these blends since 2018, ships this vial from its own facilities.

Nandrolone Decanoate, Testosterone Enanthate, and Boldenone Undecylenate in One Vial

This blend puts three long-ester compounds into a single injection. Nandrolone decanoate, testosterone enanthate, and boldenone undecylenate each appear at their proportion of the 500 mg per ml figure. The 10 ml vial format matches what other Steroid Mix use, and the multi-compound approach differs from single-substance options like Mass Stack 500 Mix or standalone testosterone enanthate vials, where one ester occupies the entire concentration.

500 mg per ml Across Three Esters

The 500 mg per ml total splits among nandrolone decanoate, testosterone enanthate, and boldenone undecylenate. Each draw from the vial delivers all three at once, while single-ester products require separate vials to combine compounds. The injection form and vial pack are standard across Xeno Labs' line, and the blend composition distinguishes this product from two-compound or four-compound mixes other labs list.
