There are so many protocols to choose from. For pure mass, post workout is the way to go. But the following protocol is the one I would try for what you want. There are many theories on insulin dosing. I like DAT'S route, as it is safe, and doesn't require high doses to get the most out if it.
First off, I would get hgh peptides to create a natural hgh pulse from your pituitary gland that the synthetic hgh can ride, making it more effective. I recommend ipamorelin as it only releases hgh, no cortisol or prolactin are secreated.
Okay, upon waking, when you have an empty stomach, take 100mcg ipamorelin and 100mcg mod grf(the mod grf makes the hgh release alot stronger when coupled with ipamorelin). This causes the pituitary gland to create a natural hgh pulse. 10min later take 2-3ius synthetic hgh. The synthetic hgh will ride the natural pulse making it alot more effective. 20min later, when the hgh clears, take 5 units of humalinR. This is plenty of insulin to get a synergistic effect with the hgh. At this time, have 60 grams of whey protein with 60 grams of glucose...honey is good as it is a split between glucose and fructose. Grape juice works, as well. You can also intake amino acids and glutamine if you so choose. An hour later have a food meal with protein and carbs. Avoid fats as humalin R is active for 7 hours and will store them. Do this exact same protocol post workout. The peptides coupled with the synthetic hgh will turn your 4-6ius hgh into 8-10ius hgh. The insulin will make your hgh receptors more sensitive, and will drive all of your nutrients, i.e. protein, aminos, glucose, into the muscles.
