Look, I'm going to give it to you straight. Based on your choices of guys you admire for their physiques, I'm guessing you're younger. I totally understand that we all want to look a certain way, but the sad and honest truth is that no matter how hard you try you won't look exactly like them. You will look like YOU at whatever percent body fat they're at and possibly at their amount of lean mass. Does this mean I think you should give up and stop trying to be the best version of YOU? No. It simply means that you should be spending time learning as much as you can with regards to proper diet and training.
AAS doesn't work miracles; it just gives a slight edge for those that need it, and allows them to continue pushing beyond what Mommy Nature provided them. I would seriously keep going at it hard, and when you can no longer make progress, THEN (hoping you're 25 by that time) I would start thinking about taking that next step. I honestly have no idea what drugs those guys take, but I can assure you that unless you're making a living from your body as they are, it just isn't worth it at this point in time to jump in and take enormous risks that can be
permanent.
I do want to say that while some comments may be seen as harsh, it's only because we see so many young guys that learn the truth about folks like Seid and figure they can obtain the same physique by injecting drugs. I don't know Jeff Seid, nor do I know how hard he works - but I can only assume that he busts his ass and has been at it for a very long time from an early age and is obviously blessed with really great genetics. We try to dissuade guys from thinking this is totally doable as shortcuts with hormones tend to only make things worse. I hope that makes sense.
Please stick around, there's a TON to learn from here and when you're ready - you'll TRULY be ready.
