What are some accredited and effective weight gaining supplements?

I'd look to protein powders, and there's a ton of them, but just using powder alone won't help you gain weight. It needs to be on top of your regular diet. As a meal substitute, it will help with lean body mass (if you're working out) but you still need the calories.

Sheesh! There's nothing hard about that. Drink a shake everyday and eat junk food. You'll gain weight real quick or just overeat every day.

You could make you own smoothies / gainer shakes with heavy cream, ice cream, peanut butter... some people might add the type of weight gain powders meant for gym bulking.

Chocolate cake

Wedding cake works for most women . Lol

not a supplement per say, but taking predisone for 8 months will cause you to gain weight quicker than anything...

doctor had me on it for nerve pain 4 or 5 years ago, went from a 34" waist to 40" in less than a year...🤔

Beer!

Chocolate shakes...fast food...and making sure you always eat more calories than you burn. Guaranteed weight gain...diabetes....coronory problems.....needing 2 seats on an airplane.

Boost chocolate twice a day and eat your regular meals can addnweight but also can increase your energy level and doesnt cost you $$
