As far as I'm aware, based on what I've read, you can use peptides indefinitely, unlike actual growth which will eventually stop your own production. This is because growth hormone releasing peptides only stimulate your own production.

Bearing in mind my age, and the fact that due to this f*%king back injury I've hardly trained for the two months since I ended my cycle, I've retained probably all I gained on cycle. I know that's not a long time off, but I don't think I've lost anything except the unwanted stuff!

As for the mod-GRF it's supposed to double the benefit of the ghrp and I'd have to say I'm sure it does that and more.

It will be interesting to see what you think. I do remember having slight doubts about whether or not it was working for a few weeks and thinking I might as well use it now I've got it, but either it takes a while to really kick in or it was the addition of the mod-GRF that really made a difference.
