I Have an opinion on this that I really don't like to post here because I don't want to entice those who have no business using it. I've talked to guys using it because someone told them it would add a ton of mass and had absolutely no idea of how it works or the risks.
I have a protocol with three shakes during the active window consisting of protien, carbs, bcaa, eaa, creatine, glutamine, and a few others with a blend of fast and slow absorbing protiens/carbs.
The problem is it does not discriminate and will shuttle fat just as well and this is why many people aren't happy with results but it's entirely diet related.
For certain people I believe it's of great use, unfortunately there aren't many people who should be using it. I have spoke to a lot of guys using it and have no idea why or how it works but just using because someone told them they could gain a lot of mass. Retarded.
It's not something to take lightly. You want zero fat during active window. With my shakes, you will prevent hypo even using pre and have plenty of time before needing a meal because glycogen will not be depleted even after training.
As far as hypoglycemia, besides the fact that you can easily go into a coma and die, the actuall symptoms suck. I recently had a hypo incident two to three times this month that I struggled to control. Immediately weak, sweating, dizzy, eyes going black, fell down twice in my house, nausea and this was all w/o slin use. I can typically control this thru diet but each time it happened after a meal. I pounder 32oz of orange juice and a brownie, didn't have glucose tabs, but symptoms remained for about an hour.
Now imagine if this hit you driving down the road or in the gym. Luckily I made it to my bed after a couple spills trying to get there. This month has been the worst for me with this since I was about 15.
Take a person who doesn't know what this is like, and I'm not talking a little low blood sugar and getting a few symptoms until you eat, I'm talking full on hypo and when you attempt to control it and it's not working and you continue to feel worse would you freak or find a way to manage? May sound like you would come up with a plan but your brain isn't working they way it normally would. You start to look act and sound like a drunk. It's not a pleasant experience to say the least.
I'm not trying to post scare tactics, this has been my experience and this was with no slin so it can get worse. I read a post recently with a guy who freaked and went hypo off 4 iu he thought, well he didnt know what he was doing and injected 40 iu.
Is this effective at what it does, yes it is, probably more so than anything else. A safe alternative with that effective but less effective is igf. And for 99.9% of people here, AAS will do everything you need it to do and have no need for slin.
I have the opinion that humalog is best for short duration but humilin for hard gainer because longer life but that's a longer time you have to be concerned of peaks.
