"Why doesn't my vial pull in the bac water?? Is it fake??"
I've gotten this question about 47 times this week, mostly about Valor vials.
Y'all are panicking because your peptides don't have that satisfying vacuum pull when you reconstitute.
Here's the thing: The pull effect has nothing to do with peptide quality.
I just dropped a full breakdown on Substack explaining:
❌ Why the "pull" is NOT a quality indicator
✅ The actual difference between vacuum and nitrogen sealing
✅ Why some manufacturers specifically choose nitrogen
✅ What you should ACTUALLY be looking for in peptide quality
✅ The lyophilization process and why both methods work perfectly fine
The pharmaceutical industry uses both methods. FDA-approved medications use both methods. Your peptides can be fire regardless of which sealing method was used.
But everyone's been conditioned to think "no pull = bad" and that's just... not how this works.
