The Scale Doesn't Lie
191XT customers, in their own words, typos and all.
I know for a fact it works I gained 13 Ibs of lean muscle mass in 8 weeks but I put the work in for sure.this stuff enables you to have the motivation to do it because the results are so fast.true story !
I started having people ask me what I was taking and I told them 191XT. With a good meal plan and training, I added 10-12 pounds of muscle in a few months. I just ordered 4 more bottles. Thanks for this amazing product guys! You have a customer for life
I was already shredded and have been my entire life but at 45 l had never been able to gain weight but at the end of my first bottle and have already packed on 6 lbs of pure muscle! Loving this stuff...
I being taking it and it's working I have put three inches on my arms and a bigger chest this works it great and I'm 50 years older and I us it ever night before bed
I'm on my third bottle and growing. No joke. I'm 60.
Been on this stuff about 2 weeks. I'm older I'm 72. I've been stuck on same weights and reps for months. Then bam my reps were going up. My workouts are pretty intense. I just feel stronger and more energy towards then end of my routine. Definitely sleeping better. I was pretty skeptical but I definitely am noticing a difference on my strength!

Everybody In Your Gym Is On Something
You've seen it. The dude who was average in March is walking around in August with traps up to his ears and sleeves that won't sit flat, and he didn't get there on chicken and rice. He's pinning. Test, a peptide stack, a little vial of IGF-1 LR3 he mixes with bac water on the kitchen counter at eleven at night.
And part of you wants what he's got. You just don't want everything that comes with it:
- Needles three, four, five times a week
- Vials from "some guy" on a forum, and no clue what's really in them
- Fake gear, underdosed gear, dirty gear
- PCT, bloodwork and a doctor asking questions
- A shoebox in the closet you hope your wife never opens
- A package at your door you could get busted for
So most guys stay right where they are. Same arms, same weight on the bar, same shirts fitting the same way they did three years ago.
What The Big Guys Are Really Chasing Is IGF-1
Here's what most lifters never hear. When the pros run hGH for size, the hGH isn't what builds the muscle. Your liver turns it into IGF-1, and IGF-1 is the signal that tells your muscle to repair, grow and come back bigger. hGH is the middleman. That's why the peptide guys skip it and pin IGF-1 straight.
It's also the hormone researchers look at for building new muscle fibers, not just making the old ones bigger. No protein powder has ever been accused of that.
The problem was always getting at it. Real IGF-1 means a needle, a vial and a guy you'd rather not text. 191XT was built for the man who wants that result and isn't going to cross that line.
Meet 191XT: Sprayed, Not Pinned
191XT is a dietary supplement spray built around IGF-1 support, with blood-flow and natural test support in the same bottle. Six sprays under your tongue before bed, hold it, swallow, lights out. Your body does its repairing and growing while you sleep anyway. This just gives it something to work with.
No vial. No bac water. No needle. No prescription. No PCT when you're done.
Higher Serum IGF-1
Men using one of the key ingredients in 191XT showed up to a 15% increase in serum IGF-1 after just 30 days.
hGH vs. Baseline
Another key ingredient in the formula has been shown to double hGH levels compared with baseline.
More Testosterone
Another key ingredient raised testosterone 37% in research. The difference between feeling like a boy and training like a man.
More Blood Flow To Muscle
One key ingredient boosted muscle blood flow by 38%. Bigger pumps, and what you ate gets where it's going.
More Muscle Cell Growth
In laboratory studies, a key component boosted muscle cell proliferation by up to 40%.
Sprays A Night
That's the whole routine. Under the tongue, hold about 45 seconds, swallow, sleep.
Figures are from published studies of individual ingredients in 191XT, including laboratory research, not of the finished formula. 191XT is a dietary supplement. It is not IGF-1, hGH, a steroid or a peptide. Individual results vary.
What The Next 90 Days Look Like
- You stop walking around sore.The day after legs used to be a write-off. Now you wake up ready to train again.“I've been taking it for 5 days now. Is it possible for it to already help me recover with in 24 hrs? Crazy, but it's true. Because that's exactly what's happening. And the fact that I get up early every morning. I sleep much better.” Troy
- Shoulders and traps grow first, same as gear.And your diet doesn't have to be perfect for it to happen.“It really does work. I just received a 6 month supply after trying out a bottle. I'm leaning out, but I'm not on a crazy strict diet. I also feel it in the gym. My traps & shoulders have definitely grown & back in the day when I used gear that was always the first place I felt it. Definitely recommend.” Mark
- Guys start asking what you're on.And you get to tell them the truth.“I will be 60 in September, I have been taking 191, tri them an primal boost along with serious hard work I'm killing it at the gym best shape of my life. My energy and strength is off the chart! Every day someone ask me what is it I'm doing” Mark l.
- Your sleeves quit fitting.Shirts go tight across the back and the chest, and the mirror starts telling a different story.“I did the full 6 month cycle. And I highly recommend it. The stuff really works a little pricey. I'm fifty four years old and i've never looked this good” Mark, 54
- And she notices.Your girl asks what happened to you. The look lasts a second longer. You walk in different, and everybody in the room knows it.

We'll Be Straight With You
191XT is not gear, and it won't do what a full cycle does. Anybody selling you something legal that matches a cycle is lying to you.
And it's not another test booster from the supplement aisle either. Those are built around testosterone. 191XT is built around IGF-1, the signal hGH works through. Different target, different category.
If you're tired of getting outpaced by the enhanced guys and you're not willing to cross that line, this is what's left. Guys who run it don't go back to the aisle.
What Lifters Say About 191XT
I'm 76 years old and have been on this now going into month 2. This stuff is crazy good. Super energy at the gym....muscle gains for certain.
I have this. Another great product. I hit my workouts lil never before. And I'm 70! Feel 30.
It works for me and I'm 66yrs old I get pumped up and people can't believe my age. I've taken 191xt for over a year but purchased 4 bottles in that period of time. It does give you size after your workout. Taking creatine with it just enhances muscle size. Great stuff in my experience.
I'm 60 and l've been using it for right at 3 months now . I don't go to the gym but I climb towers for a living. I was starting to notice I was losing muscle . Since I started this I'm feeling a little better about what I see in the mirror not to mention l'm a noticeably stronger climber than I was a few weeks ago.
UPDATE - holy cow. This stuff is amazing. Day 8 taking it and I've seen excellent results in the gym. Now, keep in mind, I'm in the gym 6 days a week and I'm pushing myself very hard. My strength has seriously increased and l've gained some good muscle
Working on my 7-8 week with 191 tx or essentially ifg-1 oral spray stacked with nitric oxide and test boost from primal muscle along with micronized creatine and a primal muscle pre workout l'm also doing a mininum of 45 grms of proteine along with a high proteine low carb diet every day in just shy of two months I seen absolutely incredible gains in lean dense completely shredded muscle increase i went from 11/12 to 12/12 inch arms all the way to over 15+closer to real 16 inch pythons and added pure dense shreded mass to my traps and even huge gain in my lats pecks incline bench decline perfectly round big cut chest triceps biceps soooo happy show pic in next comment
Im definitely stronger and lifting heavier since taking this and i have more energy snd i sleep way better!
It works. I did 4 months and had great results. Just reupped for a 6 mo. supply.
Been using for 4 years, huge gains and one of the best features is how I sleep like a rock which aids in recovery- highly recommend 191xt
It works I take before bed every night and I feel like I'm ready in the morning to take on the world
Tend to be a doubter until I see measurable results. I have a popular health metrics device on my wrist day and night. Prior to using 191xt, I was having very poor recoveries from hard days. Poor sleep, no energy... just never felt strong. Sometimes multiple rest days were necessary. After I began using every night ....Boom! - better sleep and not one single poor recovery! It definitely made a difference! BTW, I'm 70 going on 50!
Been on it for a month, loving the results!!! Sleep, energy and all around getting me cut, with my physical job and working out seeing all the benefits. I will be ordering more of this!!
I’ll admit, I was quite skeptical of the claims at first, but I decided to give it a shot. I’ve been using 191XT for 3 months now… WOW!!! I started noticing results within the first week. I just reordered and plan to continue for another 3 months. At age 45, I’m in the best shape of my life and can’t wait to see what I create with my body next. If you all have an affiliate or ambassador program, let me know. I’ve been telling everyone about this!!
I can honestly say that I was not sure about this product at first but I have been very impressed. Just ordered my second three month supply. This is great stuff and yes it also helps me sleep too.
I have to say, I tried two bottles of this stuff and believe it or not it works.
How To Use 191XT
Six Sprays Before Bed
Six sprays under your tongue at night. Hold it about 45 seconds, then swallow. It sits under your tongue instead of going straight down to your stomach like a pill. Follow the directions on the bottle.
Train Like You Mean It
191XT is powerful, but it's not magic. Eat, lift, put the weight up. It works with the work, not instead of it.
Run It 3 To 6 Months
One bottle is about a month. Muscle gets built over months, which is why most guys run 3 or 6 bottles.
“I love it!!!!! 56 years old and feel like I'm growing faster. On first month and totally notice.” Brandon, 56
“I just started taking 191xt and it speaks for itself I’m blowed away by my recovery and it’s only been 2 weeks and I’m already doing more pull-ups I do 1000 push-ups in 45 min and I’m loving it so I’m hooked and I can’t wait to try more thank you guys you rock!!!!” Eddie M.
“I'm coming to the end of my 3rd month. I can honestly say that l've seen faster results recently. Like really good. I'm assuming it's from this, since I haven't changed anything else. I was already doing good, progress was consistent every week, but it feels like this put it in overdrive.” Gregory

Frequently Asked Questions
Is 191XT a steroid?
No. It's a dietary supplement. No hormones, no needles, no prescription, and no PCT when you finish a run.
Is it actual IGF-1?
No. 191XT is not IGF-1, hGH, a steroid or a peptide. Primal Muscle positions it as an IGF-1 catalyst: a formula built around supporting IGF-1, with key ingredients that have been studied for IGF-1, hGH and testosterone.
Is it just another test booster?
No. Test boosters are built around testosterone. 191XT is built around IGF-1, the growth signal hGH works through. Different target, different category.
How do I take it?
Six sprays under your tongue at night. Hold it about 45 seconds, then swallow. Follow the directions on the bottle.
When will I notice a difference?
A lot of guys notice the recovery first, within the first few weeks. Size and strength build over 6 to 8 weeks and beyond; Topher's 13 pounds came at the 8-week mark. Results vary with your training and diet.
Does my diet have to be perfect?
No. Eat enough protein and train hard, and you'll get more out of it. But plenty of our guys, like Mark above, aren't on a crazy strict diet.
Do I need a prescription?
No. Not today, anyway. This market changes and they pull this stuff off the market all the time, which is why a lot of guys stock up on the 6-bottle run.
Do I need PCT?
No. Nothing Primal Muscle sells needs post-cycle therapy.
Can I stack it?
Yes. Guys stack 191XT with creatine, protein and Tridenosen-H all the time. Your Fitness Advisor can map out the right stack for your goal.
Which package should I get?
Muscle is built over months, not days. The 6-bottle run gives you the lowest price per bottle and a full 6 months. The 3-bottle run covers about 3 months.
Where else can I buy it?
Nowhere. 191XT is sold only at PrimalMuscle.com. If you see it anywhere else, it didn't come from us.
How fast does it ship?
Orders typically arrive within 4 to 6 business days.
What if it doesn't work for me?
You're covered by our 90-day money-back guarantee. Call or email us and we'll take care of you.
Can I take it with medication or a medical condition?
Talk to your doctor before taking any dietary supplement if you have a medical condition or take medication.
