regarding Slin..
5iu of slin post workout is more then a safe and reasonable thing to try out. heck my 120 pound wife runs 5iu of sin post workout with only 25g carbs and doesn't go hypo.
I personally run 5-10iu of slin often times with NO carbs (for certain reasons, not recommending anyone do this)
so, YES you'll be just fine running that low dose of slin post workout with 50g of carbs. after awhile you'll find your personal sweet spot of how many carbs you need with how many iu of slin.
however, if your NOT dirty bulking and trying to put on a bunch of size , then don't add carbs to your diet with slin usage, simply use your slin usage to supplement your already optimized diet .
see my post here on how not to get fat using insulin

as for the secondary peak that comes from regular acting insulin about 2 hours later. just be sure that around this time is where your whole food meal comes in.. but again, if your dosage is very low, like 5iu, then you may never even notice this secondary peak.
for me, if I pin 25iu pari workout, then I be sure to get in my carb drink and also a whole meal by the 2 hour after mark.
couple other quick notes.
insulin can actually help you stay lean. insulin has the ability to up-regulate the conversion of T4 into T3 and help your metabolism keep revving along.
people get fat off insulin not because of the insulin itself, its because they are so afraid of going hypo they keep stuffing their face with sugars.
the idea of taking in fats while your using insulin will make you fat because the insulin will store the dietary fat, sounds right to bros in the gym. but truth is, FAT does not require insulin to be stored as fat. dietary fat is stored as body fat via an enzymatic response , not an insulin response. so , diet dependent, fat is stored as fat no matter your insulin use.
we are using insulin to drive protein, glycogen, nutrients, minerals, creatine, etc. into muscle cells . the reason we don't really want to take in dietary fat after taking exogenous insulin is because the fat will slow down the digestion of these other nutrients we want to uptake right away.
again, the dietary fat you consume can/will get stored as fat no matter if insulin is present or not.
