Peptide Stack Builder

Combine multiple compounds into one protocol. See the exact units to draw for each peptide or GLP-1 on a to-scale insulin syringe, a combined weekly schedule, and the aggregate cost per week and month.

Loading the Peptide Stack Builder

Add your compounds, set each one's reconstitution or liquid strength, and read the combined draw, weekly schedule, and cost.

How to build a peptide stack

  1. 1Add your compounds. Start from a popular stack preset or add each peptide or GLP-1 you plan to run together.
  2. 2Set each compound's strength. For every compound, enter your vial strength and bacteriostatic water, or switch to liquid mode and enter a known concentration.
  3. 3Enter dose, syringe, and frequency. Set the dose, pick your insulin syringe, and choose how many times per week you inject each compound.
  4. 4Read your combined protocol. See the exact units to draw for each compound on a to-scale syringe, a combined weekly schedule, and the aggregate cost per week and month.

Common 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 for recovery. The Stack Builder lets you plan every compound side by side and see how the doses come together across a week.
Does the Stack Builder mix compounds in one syringe?
No. It calculates each compound independently and shows the exact units to draw for each one on its own to-scale insulin syringe. Whether compounds can be combined in a single syringe is a separate compatibility question you should discuss with a licensed professional.
How is the aggregate cost calculated?
For each compound you can enter a vial price. We work out the cost per dose from the vial strength and your dose, multiply by how many times you inject per week, then add every compound together for a combined weekly and monthly total.
Can I save a stack?
Yes. Signed-in users can save each compound in the stack to My Doses, and you can share your whole stack with anyone by copying the page link, which encodes every compound and dose.
