almost everything at GNC is either way overprices, or worthless.
And no, you cannot get that at GNC. But, GNC will probably have the supps that I listed minus the CEL stuff.
As for dosage, it doesn't matter how long you've been lifting. dosage does not depends on your experience in training. It depends on how your body reacts to these compounds. With SD, week 2 is when you really start getting the gains/sides, so you probably won't feel too much in week 1.
rule #1 of supplement purchasing... order everything online... you will find more potent and beneficial items that are only sold online. take a look at the board sponsors as well.
days and days of research is a drop in the bucket compared to what you should be doing. Try weeks and weeks... or months and months. At least you did one thing right, and asked questions on the forums. However, you ignored much of the advice and jumped into your cycle anyways w/o having things planned out. So that probably means you are only going to choose the take the advice that you feel is easy to follow, and selectively ignore advice that you don't want to hear.
Firstly, you needed to PRELOAD milk thistle for a week prior to your cycle. Also, SD destroys your lipid profiles, so you want to take a supplement for that, most of which take a week to kick in. Most experienced people on here have done other PH/DS/AAS before, and have had years of experience with such substances. What makes you think that in your "Days and days" of research, that you know anywhere near 10% of what they know?
We will give you good advice here, but don't expect any support if you ignore it, and then come back later because you f*ked yourself up or feel like sh!t.
But back to being helpful... I owuld place an order for support suppls immediately, call and ask if they have it in stock, and order by phone to get it shipped to you ASAP. Also, use all the support supps listed, unless you are getting bloodwork done and have the experience to know what you need and don't need.
