There is zero chance that you will grow too much lean tissue so you can't go into your class. Everything possible to gain as much muscle now should be done. And when you start the diet, whatever you yourself think your finishing weight will be when peeled will likely be at least 20lbs less. No one gets too hard, almost everyone is just a little too smooth, especially first timers.
Whatever you do, you will positively NOT gain too much muscle, and you need every gram of muscle you can squeeze out of whatever you are doing.
Last week, things may not play out the way you expect. Someone could be worried they will gain too much loading but often the result is not gain, probably more like at least another 5lbs lost. Especially if you do diuretics. Stress adds to this.
This is just my opinion and guesses, no need to take offense if you feel you "know" different. Maybe you do. I'll give you major props if you ever go on stage. But to do that time is running put for committing to a show. You should register for a specific show on a specific date with the promise of not backing out unless dead. An "open to change plans" approach will most likely not have you actually compete.
You need a date, you need a plan not open to major changes. I think, you would benefit from some leg work even if you competed in the shorts division. You need to add as much muscle as possible between now and prep, constant anabolic state, without going over a
set bodyfat limit.
good point about picking a date and doing it
i am incredibly competitive so this will help my insane drive even more so

i'm thinking sometiime in aug/sept
i've been playing with the slin this week and it seems post workout is the ideal time to deploy it, i'm doing it one post workout not both as i am doing doubles doing it daily even though justin harris says limit it to twice a week max
i'm hitting 80-100 grams pro both postworkouts
and agreed bout keeping the bodyfat in check, i won't go over 8% EVER
leg is still on the mend doc says 3-4 more weeks of no training so that is what it is, but why add mass on my legs? this WILL NOT help my case as it's all bout DELTS, LATS, PECS, AND ARMS
i should consult a MP expert and ask him where i need to add the most muscle i'm fucking driven to thinken my arms right now but maybe i should focus on lat width

i used dbol this summer and kept a tight and tiny wasit so that's good shit to know, var and tren also allow the wasit to stay tiny but not sure bout deca/npp maybe i should just x it out completely
drol also thinkens and widens my wasit if i remember correctly so...
and slin also can thicken and widen it but i can depoly it for awhile for it's anabolic effects and then drop it the fuck out 8-12 weeks post contest
harris says you can keep the waist tight on slin/log twice a week max
