Research Guide
Most research compounds are available in multiple vial strengths — 5mg, 10mg, 30mg, even 60mg formats. The right choice depends on three factors: the length of your research protocol, the reconstituted stability window of the compound, and cost efficiency per milligram.
Sophisticated researchers evaluate compounds on price per milligram, not vial price. The math is simple: divide the vial price by its milligram content. A 10mg vial at $119 works out to $11.90/mg, while a 60mg vial at $349 comes to $5.82/mg — less than half the per-mg cost. Larger formats consistently reward longer research timelines.
Bigger is not always better. Once reconstituted, peptides have finite stability windows — most remain viable for approximately 28 days refrigerated, while some (tesamorelin, for example) degrade faster at 14-21 days. A vial that cannot be consumed within its stability window wastes material regardless of per-mg savings. Lyophilized (unreconstituted) vials, by contrast, remain stable for 12+ months refrigerated — so ordering multiple smaller vials and reconstituting sequentially is often the optimal strategy for long protocols.
Match vial size to your protocol: calculate total milligrams required, divide by the compound's reconstituted stability window, and select the vial size that minimizes both waste and per-mg cost. Our on-site reconstitution calculator can help convert between vial strength, water volume, and research amounts.
Plato Peptides offers multiple sizes across the catalog — including a 60mg Tirzepatide format unavailable elsewhere — each with COA documentation.
