i'm not one of those people who think it matters much what specific compounds people run, just the total overall weekly dosage when it comes to making gains, you know? more anabolics, more gh = mo' bigger. so to speak. if you want to have added secondary effects - like hardness/dryness or if you want to get your muscles bloofy as hell with that type of look like someone stuck an airhose into your biceps - then you use specific compounds like winny or anadrol but i don't think it matter otherwise.
with regard to your second question, i don't like to ever claim i'm knowledgeable, or that i know a lot. i mean, it's called an "opinion" for a reason, and that's because everyone always thinks they are right about everything, regardless. i'm not arrogant or conceited enough to think i'm never wrong.
with that said though and about the GH, i liked dosing it in smaller dosages, multiple times a day and every 3 hours. i was running about 2-3iu every 3 hours, roughly. it's hard to tell from just appearances if it makes a huge difference though, but i recently read a post by gh15 stating he suggests the same thing: smaller dosages pinned often instead of few large dosages - so there you go. there was also a medical study that was done specifically on this that i always reference, in which total gh dosages were equivalent, and the dosing protocol that mimicked a pulsatory manner (i.e peaking blood plasma levels of growth hormone and then allowing a trough before peaking gh levels again) produced better results than a steady even infusion of growth hormone throughout the day.
