Gentle swirling (not shaking) until powder dissolved
But theres no evidence that those (or other) growth-hormone-related peptides live up to influencers claims of better muscle retention or that theyll help melt belly fat or make you fuller, tighter, and leaner. CJC-1295 and ipamorelin are often combined into one vial (like the one I purchased)
This has nothing to do with b12 status and everything to do with excessive caloric deficit and insufficient protein intake relative to the rate of weight change
So people at greatest risk for deficiency include those with low stomach acid (e.g., older adults and people on proton pump inhibitors or antacids) or low IF production (known as pernicious anemia), people on medications that interfere with B12 absorption (such as metformin), people who have had gastric surgery, those with GI conditions that impair nutrient absorption (like celiac or Crohn's disease), and people on vegan and vegetarian diets
In reality, creating an effective and safe stack requires a deep understanding of how different peptides interact
