A blend is two or more compounds lyophilised together in one vial at a fixed ratio. We offer one: BPC-157 with TB-500, 10 mg of each. The question is not whether a blend is better or worse than single vials, but which design fits the research question.
What a blend gives you
One reconstitution, one solution, one draw per sample. The ratio of the compounds is fixed by the manufacturer, so every sample contains the same proportion, and the handling steps that introduce variability are halved. For protocols that always use the two compounds together at the same ratio, a blend is simpler and reduces the number of vials in the refrigerator.
What a blend takes away
Flexibility. If a design calls for varying one compound while holding the other constant, or for staggering the two in time, a blend cannot do it. Interpretation also becomes harder: an observation after a blend cannot be attributed to one of its components. For that reason exploratory work usually starts with single compounds, and blends are introduced once the combination itself is the object of study.
Stability of mixed solutions
Peptides in one solution do not react with each other under normal conditions, but they share the solution's pH and the same degradation clock. The least stable component sets the usable period of the whole vial. Treat a reconstituted blend like the more sensitive of its parts: refrigerated, dark, used within a short period.
Our blend
BPC-157 / TB-500, 10 mg + 10 mg: the two most studied repair peptides, equal amounts, certificate of analysis on file.
Both single compounds are also available separately in 5 mg and 10 mg vials: BPC-157 and TB-500.
