What’s a Stack?
From ReVia
Several peptides, one vial
A stack is a blend: two or more complementary compounds combined in a single vial at fixed ratios, rather than bought and handled as separate vials.
Reconstituted once
Because the compounds share a vial, the blend is reconstituted once and drawn as one solution — the ratio between compounds is set at the point it is blended, not at the bench.
Formulated around a research goal
Each blend pairs compounds that are commonly researched together, so the vial is organized around one line of research instead of assembled ad hoc.
A blend, or separate vials?
Neither is the right answer on its own. The difference is where the decisions get made — at the blender, or at the bench.
One blended vial
- One vial to store, label and track
- One reconstitution, so one chance to introduce error
- Ratio between compounds fixed when it was blended
- The whole vial moves together — one compound cannot be varied alone
Separate vials
- A vial per compound to store, label and track
- A reconstitution per compound
- Ratio decided at the bench, every time
- Each compound can be varied on its own
Three things worth checking
Ask these of any blend, from any source — including ours.
Does the COA cover the blend?
A certificate for each ingredient is not the same as a certificate for the vial that was actually filled. Ask which one you are being shown.
Is the ratio stated?
A blend is defined by its proportions. If the label names the compounds but not how much of each, the vial is not fully described.
Which compound sets the handling?
Storage and stability follow the least forgiving compound in the vial, not the average of them.
