Crazy Nutrition Mass Gainer
Best mass gainer for skinny guys trying to bulk up
The Crazy Nutrition Mass Gainer is our favorite mass gainer for skinny guys looking to bulk up and an essential part of your bulking supplements.
Easy to drink, loaded with proteins and carbs, and available in two different flavors, the Crazy Nutrition Mass Gainer is a perfect way to start packing on the mass in a hurry.
Each serving (four scoops) is loaded with 55.29 carbohydrates, 39.73 of protein, and 10.42g of fats for an optimal blend that will help any skinny guy bulk up.
Part of bulking up requires having an excess of calories and carbohydrates over the course of the day from which your body can build muscle mass from.
The Crazy Nutrition Mass Gainer helps you hit those increased caloric goals while also using special enzymes to aid in digestion and prevent wastage.
Also, Crazy Nutrition doesn’t load up their mass gainer with crap fillers like maltodextrin, which is loaded with a high glycemic index and can cause unnecessary blood sugar spikes.
- Loaded with carbs and protein for fast bulking
- Available in two yummy flavors
- No fillers
- Delivery can take a while
Ultimate CRN-5 Creatine
Best creatine for skinny guys trying to bulk up
Creatine is one of the most widely tested supplements on the planet. It’s efficacy has been shown over and over again in countless studies.
As a quick example, [cite two studies]
While there are literally thousands of creatines on the market (Amazon, for example, has over 345 pages of results for “creatine”), there’s no better creatine for skinny guys who are trying to bulk up than Ultimate CRN-5 Creatine.
The Ultimate CRN-5 has a list of clean ingredients with no fillers, a surprisingly good taste, multiple flavors, and proven forms of creatine that is perfect for skinnier men looking to pack on size.
Each serving of Ultimate CRN-5 Creatine includes:
- 3,750mg Creatine monohydrate
- 500mg Di-creatine Malate
- 500mg Tri-create Malate
- 250mg Tri-creatine pyruvate
The thing I like most about the Ultimate CRN-5—besides the proven ingredients, obviously—is how palatable it is. Creatine is rarely good in terms of taste, but the CRN-5 comes in two decent tasting flavors, including lemon & lime and Orange & Mango.
It’s also available in single units, or what I use, as a subscription, which also helps you save a few bucks each month and also helps automate your supplement orders.
- Proven ingredients for building mass
- Tastes good
- Multiple forms of creatine for maximum effect
- Easy to digest
- Subscription option to save money
- Limited flavors
Crazy Nutrition Tri-Protein
Best protein powder for skinny guys trying to get big
A good protein powder is absolutely essential for bodybuilders of all levels, but especially for skinny dudes.
Research on protein and the development of muscle mass and strength overwhelmingly show the importance of increasing dietary protein to increase size and strength.
A meta-analysis published in the Journal of the International Society of Sports Nutrition (Bosse et al., 2012) revealed what many of us already know; that higher protein interventions provided the greatest results in seeing improvement in muscle mass and strength.
But with all of the proteins out there, it can be really overwhelming trying to figure out which one is the best for skinnier guys.
The Crazy Nutrition Tri-Protein is our top choice for the best protein for skinny guys, and it’s not even really close. There are a few reasons why we love this protein specifically, including:
Excellent taste – The Crazy Nutrition Tri-Protein is one of the best tasting proteins we’ve tried. It also comes in multiple flavors.
24g of protein per serving – Each serving (two scoops) has 24g of protein. Drink two of these a day along with a well-balanced diet and you will be well on your way to hitting your daily protein-per-kg goals.
Multiple protein types – This protein has several different types of protein, the two most important of which are whey isolate and casein.
Whey isolate is the best overall protein for muscle synthesis (Tan et al., 2009) as it is loaded with BCAAs, including leucine, which is the most important BCAA for building muscle (Norton et al., 2009).
It also features a significant amount of casein, which is a slow-absorbing protein, perfect for elevated protein (and enhanced recovery) in your blood hours after drinking the shake (Miller et al., 2014).
The end result is a protein that tastes great, is packed with proteins for both immediate absorption and extended recovery, helping skinny guys and lifters to recover faster and pack on size faster.
- Multiple types of protein for maximum muscle recovery
- Easy to digest
- Tastes really good
- No fillers

Primesteroids Ultimate Stack
Best muscle building bulk stack for skinny guys
Okay, we’ve got the mass gainer, protein, and creatine covered. What’s left?
How about a bulk stack that is specifically formulated for generating insane results in the gym, the Primesteroids Ultimate Stack?
The Primesteroids Ultimate Stack is a four-product group of supplements that mimics the effects of steroids and is full of proven ingredients that will help the skinny lifter pack on bulk with less effort.
The bulking stack includes:
D-Bal – A synthetic (and legal) alternative to Dianabol, the most effective anabolic steroid on the planet.
The Primesteroids d-bal includes several key mass-building ingredients, including L-Isoleucine, suma root, Ashwagandha, Tribulus terrestis, andmethylsulfonylmethane.
These proven ingredients raise natural testosterone levels, reduce inflammation and increase muscle mass and strength.
Testo-Max – A testosterone booster, the primary active ingredient is D-aspartic acid.
One study, published in the Journal of Reproductive Biology and Endocrinology, showed that D-aspartic supplementation increased testosterone levels by a whopping 42%.
DecaDuro – One of the keys of putting on bulk fast is increasing the speed of recovery between workouts. The faster you can recover, the harder you can work, and the more size you will put on.
DecaDuro includes wild yam (promotes DHEA), ginseng, L-arginine, and other proven ingredients that kickstart recovery after a big lifting session, cutting down how long it takes to bounce back.
Trenorol – An all-natural alternative to the anabolic steroid Trenbolone, this supplement includes beta sitosterol (a steroid precursor), samento inner bark, and nettle leaf extract.
These ingredients collectively increase muscle mass, dilate blood vessels for increased blood flow through muscles (and raging pumps after lifting), and raising free testosterone levels.
Put all together, the Primesteroids Ultimate Stack includes a ton of bulk-building and performance-enhancing ingredients into one easy-to-take stack.
While it’s not cheap by any stretch of the imagination, costing around $180 for a month’s worth of bulking supplements, it’s perfect for the skinny guy who is ready to unleash some serious bulking gainz in the gym and on the scale.
- Tons of scientifically proven ingredients
- Excellent for recovery, performance, and building muscle
- Perfect for skinny guys struggling to bulk up

Best Supplements to Help Skinny Guys Bulk Up — FAQs
How do I start bulking up?
Before you start buying supplements, it’s important to understand the basics of optimizing your diet.
Track your calories and macros (fats, proteins, carbohydrates) for several days to see how much food you are taking in. This will give you a clearer picture of what macros need to change.
From there, put together a workout plan that is focused on size and hypertrophy, adjust your diet, and then get started with supplements to round out your bulking plan.
Should skinny guys take protein or creatine?
Skinny guys looking to bulk up should take both protein and creatine. Both are supplements that have been extensively studied over the years.
Creatine has been shown to increase muscle mass, strength, exercise performance, and can even help brain function. The International Society of Sports Nutrition backs creatine so much that they put out a position statement identifying its benefits and safety (Kreider et al., 2017).
Protein has similarly been studied, with multiple studies (West et al., 2017) showing that protein supplementation “enhances whole body protein metabolism and performance recover after resistance exercise.”
Both protein and creatine are affordable and deserve a place in the supplement stack for skinny guys looking to add size and strength.
How long does it take for skinny guys to add bulk?
The amount of time it takes for a skinny guy to add size depends on several factors, including exercise frequency, diet, supplementation, and genetic factors.
According to a meta-analysis published in the International Journal of Environmental Research and Public Health (Krzysztofik et al., 2019), healthy adult males could expect to gain 0.5 to 2 pounds of muscle per month with an optimized diet and consistent resistance training.
Can I do cardio while bulking?
There is a persistent myth that cardio will erase muscle mass. This is not the case, however.
Studies with various age groups showed that aerobic activity can actually prevent strength loss (Crane et al., 2012).
There is a point of diminishing returns, however.
According to a study published in the Journal Advances in Nutrition (Yarizadeh et al., 2021), extended cardio workouts (60-75 minutes and longer) start to recruit more fatty acids and amino acids for energy, reducing muscle mass.
Ultimately, skinny guys should be focused on higher protein intake, caloric surplus, and consistent resistance training for maximum bulking. Adding cardio to the mix won’t affect muscle mass growth.
