Good for you brutha! Not too many guys would forgo the extra pump sensation and use the igf post workout instead! However, heres the thing, it doesn’t matter whether you use it pre workout or post workout , its going to work great in terms of shuttling / forcing more nutrients into the muscles and helping with recovery / growth and last but not least regardless when its used, it will still make your body burn fat for energy, and this point is what most people do not realize and its rarely talked about.
For anyone curious about this or who would like to fact check it, you can find actual studies posted on this here at MuscleChemistry and of course google it or go to pubmed or one of the other sites where you can find these studies posted!
In closing, I would also like to say that the pump people talk about from taking igf 1 lr3 pre workout, is NOT a guarantee or set in stone, and some guys love the overall results from the igf and never really experienced those skin splitting pumps, which is ok! Plus when were talking about taking igf 1 lr3 pre workout for the added pump, a lot of it has to do with timing your carbs so that the IGF forces more nutrients in to the body / muscle then would otherwise be absorbed hence (insulin-like) , and this is what causes that insane pump, so timing is also key!
