so i decided to try a very small amount of synthol on my biceps and tris but the thing thats holding me back are the dangers of hitting an important nerve, i cant find info on where these nerves are exactly, can someone tell me if this should be a concern?
Absolutely a real valid concern. Make sure you follow Big "A's" how to inject guide. if you hit the nerve forget about that arm for a good while. This can happen with anything you site inject though. If you hit the nerve in your bicep forget about flexing it for about 4-5 months, it will be useless. Sucks big time.
If you inject in the locations shown on www.howtodoinjections.com , the chance of hitting a major nerve is basically non existant. If you get close or hit one of the tiny ones, you will just get a bit of pain and the muscle will twitch.
