whats up bros. i got a question here for a friend of mine who is 4 days into a tren only cycle. he is 6 foot 180 and has been lifting for 2 years he has done 1 prior cycle of tren 8 weeks ago and packed on 15 solid pounds. maintained these gains very nicely and has started back up after a 2 week break from lifting. he has taken .25 in each shoulder the last 2 days and is experiencing sorness in his shoulders, upper back and chest without working back or chest yet this week. i kno tren is very powerfull, could this be growth pain? what ya guys think????
