Hey man, you're right as far as similar growth is concerned, in addition to similar features and gauntness-it makes it difficult when it comes to neckline because the chin and the adam's apple is bulging (at least in my case). People that are a little bigger in that region-more neck fat/round faces- seems to have more coverage or at least it may be an illusion. I think you should stick with your growth or at least keep tabs on my thread so you can visualize what to expect for the upcoming weeks. I can already tell that you will probably have a pretty solid goatee/mustache (mustache actually has growth in the "middle" under your nose unlike myself-two separate parts it seems).

For sure stick with the 13 weeks and even more so if you are rockin' it proudly and caring for it properly. With features like ours we can sort of pull off crazy/weird facial hair I would like to think based on our gauntness and exaggerated features-large nose, adam's apple, etc. similar to that of Adrian Brody, Guy Fawkes, or any assortment of pirate or conquistador. So if it starts growing out weird, I think we can rock it. If you have any questions let me know, but give it TIME, and consider this a new hobby/training regime.
