Man. The Geno pens are the size of dildos. They are huge. I like pens but just not Genotropin. Simply because they are so big and they are complicated. There are much better options for pens in my opinion. Don't get me wrong. I love Genotropin. That's what I'm running now but in genos, I prefer the cartridges. Most others I prefer the pens.
For me, Humatrope vials cost at least 30% more than Norditropin or Genotropin pens and the same price as Saizen vials and Genotropin cartridges(which are basically vials). China gh is less expensive but...... It's China gh.
A little fatherly advice; this is your 6th post....and it comes off as desperate....which could easily lead to you getting scammed. Sometimes it's not what you ask but how you ask it.
