Should i be concerned if i see a COA from October for CJC on Modern research?

I saw someone say to not get the blend. Does this still hold true.

Anyone running the Ipamorelin/cjc blend. I noticed Dereks protocols say to run for 16 weeks. I ran the numbers and that's a ton of product lol. Anyone run less than that and gotten good results?

If i get the 5mg/5mg blend. How much bacwater to reconstitute and what research for the daily dose for twice a day?

When it comes to Ghk-cu/KPV is there any reason i should choose the 50/10 over the 50/20 if i want to research long term? Is there a cycle i should research this on?
