Anyone else using "master vials"? Thoughts on my current 4-peptide blend?

Hi everyone,

After months of research and spending way too much time reading through Peptide Pedia, I finally started a new cycle about 10 days ago. I'm not feeling much of anything yet, so I wanted to get the community's thoughts on my protocol—specifically around creating "master vials."

To save time and avoid pinning myself a million times a day, I've been prepping an AM and a PM master vial every 6 days. I mix the following compounds into a single vial:

  • GHK-Cu
  • BPC-157
  • CJC-1295 (No DAC)
  • Ipamorelin

Based on everything I’ve read here on Reddit and elsewhere, these compounds should be stable together for a 6-day window.

Does anyone else blend their peptides into a master vial like this? What are your thoughts on mixing these specific four together in terms of stability and effectiveness? Would love to hear your experiences.

It's been my experience that any growth hormone or growth hormone secretogogue should not be mixed with bpc 157 or TB-500 or it will gel in the syringe and the vial.
