If you've been reluctant to include your delts read this. I'm 4 weeks into this prop deca cycle and just couldn't get the pain to let up and kept rotating between just glutes and quads (eod not ed). Quads would hurt bad enough it was hard to walk. Rotating this way it would be a week before injecting the same site twice so I thought no big deal. Yeah, right! Both quads still hurt and I've got a golf ball sized lump in my left glute.
So many guys on here said to do my delts so yesterday I did. WTF!! Not one fricking lick of pain, or discomfort. What's up with this little muscle compared to the two biggest in the body? Doesn't make any sense, but wth, it works. And it went real smooth and comfortable.
The lesson learned? Listen to the swamies and gurus.
