igf1 lr3 and contest

i am planning on doing a contest in may of next year and want to know if by taking igf1 the last 20 days before the contest is a good idea. i think it would be from what i'm hearing, i could probably get another 10-15 lbs of quality muscle and get super vascular. the pumps would help too on the day of the show. any help is appreciated. i will be running prop+eq+maybe winny for the cutter

no way shape or form are ya gonna gain 10-15lbs of quality muscle on anything in 20 days or even 2 months for that matter, and it tends to bloat ya so it might not be so good precontest bro

i meant in the time before the show. not from the igf. if it were that good i'd only use that. it was a conservative guess at how much i might gain in the next year, realistically probably around 15lbs. i'm looking at igf for the pumps and vascularity. haven't heard anything about bloating w/ it.
