Let me know how the hcg goes after reading and reading I'm going to run it next cycle... R u gonna pin the flute or belly the vid repo hooked up shows belly but a lot of my readings said glute.
You can actually pin either place just fine - and can even pin IM - although I prefer subq for hCG
When pinning IM - peak concentrations occur approximately 6 hour after IM injection.
Subcutaneous injections will have a peak concentration 16-20 hours after injection.
Z's hCG is awesome - and here's a little testimonial...
My wife and I are planning on having a child this year - and will have to use in vitro.
They tested my - "stuff" - and looks like by boys/girls are healthy and strong swimmers.

The doctor asked if I was on steroids - and of course I said ... "NO."

I told her I had my test levels check last year and was going to do so again with the possibility of testosterone therapy - and asked her this...
... would the reason for not tacking testosterone, be that it will shut down my natural testosterone .... "and she said - yes."
Well - I've ben blasting and cruising for over a year (mostly blasting) - while running Z's hCG.
500iu twice a week - 5 week on and 1 week off ... "then repeat."
While doing this - my test came back very healthy - and not being shut down.
- Plus my balls are still BIG!

However - after my conversation with the doctor - I'm now "only" running hCG - test - and hGH - until they do the insertion for the baby.
... "then I'm going to blast like a MOFO!"
