Peptide Stacking Basics
A peptide stack is two or more compounds run together as one protocol, such as BPC-157 with TB-500 for recovery. Each compound is reconstituted and dosed separately, with its own concentration and draw. Planning a stack means calculating every compound individually and combining them into one weekly schedule and budget.

What a stack is
Stacking means running more than one compound at the same time as a single protocol. Popular examples include the Wolverine stack of BPC-157 and TB-500 for recovery, and the GLOW stack that adds GHK-Cu for skin and tissue support. The idea is that complementary compounds together address a goal more completely than one alone.
Stacking does not mean mixing compounds in one syringe. Each compound is reconstituted separately, has its own concentration, and is drawn and injected on its own schedule.
Planning each compound
Because every compound in a stack has a different strength and dose, each one needs its own reconstitution math. Work out the concentration and the units to draw for each compound individually, exactly as you would for a single-compound protocol. Only then combine them into a weekly plan.
A stack builder does this side by side: it holds each compound's vial strength, water, dose, syringe, and weekly frequency, shows the exact draw for each, and assembles a combined weekly schedule and an aggregate cost per week and month.
Practical cautions
Running several compounds at once multiplies the number of injections and the total spend, so plan both. Whether two compounds can safely share a syringe or an injection site is a compatibility question that goes beyond dosing math and should be discussed with a licensed professional. The tools here handle the arithmetic; they do not recommend which compounds to combine.
Frequently asked questions
What is a peptide stack?
A stack is two or more compounds run together as one protocol, such as BPC-157 with TB-500. Each is reconstituted and dosed separately, then planned together across a week.
Can I mix stacked compounds in one syringe?
The dosing tools calculate each compound independently and do not assume they share a syringe. Whether compounds can be combined is a compatibility question for a licensed professional.
How do I calculate doses for a stack?
Calculate each compound on its own, deriving its concentration and units to draw, then combine them into one schedule. The stack builder does this side by side and totals the cost.
Does stacking cost more?
Usually yes. More compounds mean more vials and more injections, so plan the combined weekly and monthly spend before you start.
