    Great stuff

    I’m 36. 210 right now. Coming off a 7 month layoff, which I was 170 lbs. 3 months ago. I’ve been up to 230 with bit of abs showing. Did a couple contests in my early twenties. So I’d say I’m an experienced lifter. Its not something that makes me feel like I’m super energized and bouncing off the wall. But I do get good energy from it. Used while on cycle. So can’t measure actual muscle gains. But I can say, after having to prematurely stop abombs after a week, because they killed my appetite, taking this kept my strength up just as well as those did. All my abomb workouts that week were up I weight and reps, but even stopping those and using bulk. The weight and reps continued to improve. So this definitely works. I will never go back to other mainstream “proprietary blend” garbage again! Bberry is good. Not super sweet, not a bad taste at all. Haven’t gotten to apple yet. Good, clean, quality product that actually improves my training. Love it

    CHUG-N-DESTROY!

    Focus, energy, pump all great! No jitters, or uneasy feeling, just hardcore focus while I destroyed the iron! Quality ingredients and amounts! My gains say yes please! Don’t worry about the tingling, it’s natural, and will subside. I rate 9.8 out of 10. It’s taste is not good, but those looking to destroy the gym, just chug and prepare to destroy! PR’s are on the way!

    Pre work out

    I have a question. Looking for the best work out for women. Which one do you recommend? I had a friend recommend pre series bulk. But I was looking at the other products you have online. What’s your recommendations? I’m looking to gain muscle.

      Re: Pre work out

      PreSeries BULK can be used by both men and women and is a great pre-workout choice. Another popular choice would be Cellucor C4. However, there are pre-workouts formulated just for women such as Gym Vixen Sexy Charged, Promera Sports Women’s Elite, and LeCheek Nutrition Hottie. Also, Gym Vixen is a made-for-women brand that has a range of products such as Sexy Whey and Sexy Recover which are specifically designed for women that may help you gain the muscle you seek.

    Great Pre

    Look, I’ll level with you. This stuff tastes bad. But you’re not working out and taking supplements for their taste. If you want something that tastes good, just give up now and go eat ice cream. Mix this stuff up and drink it as fast as you can. It kicks in in about 30 minutes. It will give you a ton of energy in the gym and it will also help you recover when done. The good people at transparent labs know what they’re doing and they give you all the goods with none of the bs. I’ve seen gains in both strength and size while taking this. Be sure to drink plenty of water!

      Since PreSeries Bulk is designed to be a pre-workout supplement, it may be helpful to take a post-workout supplement (such as a protein powder) to help activate the muscle building process.

      Re: Dr.

      While added Creatine can be found in many pre-workout formulas, PreSeries BULK uses BetaPure Betaine Anhydrous to increase the body’s natural creatine production. This helps to reduce bloating while increasing muscle pump and energy.

    Best Pre Workout

    I recently just purchased the pre series Bulk in replace of my previous pre workout. And honestly it is awesome. The tingly sensation is not too overwhelming and the pumps are great. I took the Bulk 15-20 minutes before my workout and I was able to have heavier weight and more reps than before. The pumps are great and makes you feel awesome all the way through and past your workout. I was at the gym for about 2 hours and I felt like I could go for another round! The only reason I would say not to get this is if you don’t want to see results. I highly recommend this product!

    BULK PRESERIES

    This review may be a bit premature. I received the product just over one week ago and first used one-half serving then I went to two-thirds and neither of those did much of anything with strength, concentration or pump. I then went to one full serving and it seems I did experience an energy boost but no incredible pump. I will say though that I am performing Olympic-type lifts and very little bodybuilding work. I did some curls and triceps pushdowns to test the pump and there wasn’t much.

    I found the flavor to be a little bitter but very tolerable and no problem at all to take. I would not be one bit concerned about that. I rated BULK at three stars because it seemed to do little and costs a lot. I would still recommend that you try it for yourself as it may be fantastic–for you.

    Feel size and strength next day!

    This workout supplement should be taken 1-hour before workout but it really does work unlike other pre-workouts I’ve been trying before. You feel the size of the muscle and the strength already the next day. Most others I’ve tried give you a rush and strength during workout but the feeling is gone the next day. Not so with this product! Will order again definitely

    Legit the best preworkout

    C4 makes my lips itch & face. Bullnox -even from kissing BF along with a bunch of others. But THIS WORKS THE BEST! I can take it at 6pm(1-2scoops)I drink most of it before working out 30min before and the last 3 sips 5 min before I start to lift weights. I can focus so well & get those extra pumps! Wakes me up when I’m yawning my way through my bike warm up. Best part of all I’m caffeine sensitive-this doesn’t give me jitters or makes me feel nauseated or light headed! And unlike other products, even if I take it at 6pm I’m stil able to fall asleep no problem! Def recommend.

    everything you need and nothing else

    pre series bulk is by far the best pre workout I have used . it’s loaded with everything you need and no artificial sweeteners. the taste is okay, not great. I’ve only tried the blue raspberry so maybe Green apple is better, but if your serious about lifting this is the product you want! I’d like to try their stim free pre workout in the future. definitely hooked on transparent labs!

    not a fan

    Profile: excellent. Transparent Labs did a great job of giving full dosages on all ingredients
    Mixability: Excellent
    Taste: Let’s face it, taste is subjective, but for me, this is the worst tasting supplement I’ve used. Very bitter. Might be because they use Stevia (which is a good thing).
    Effectiveness: This is what ultimately matters, and to me it was not a game changer. Decent pumps, so-so energy, and focus was just alright. Nothing really stood out to me.
    Price: With the dosages of the ingredients, it’s probably ok, but for the results I got, too expensive.
    Bottom line- When I finish what I bought, I will not buy again.

    Best Prework out Ever, No better choice

    Three weeks into the jug and I can tell you the endurance factor is untouchable. I deal with the ok taste because its healthy and safe. You get used to it quick because I can hit the gym hard every night and leave after two hours with lots more bang left in me. The endurance is almost indescribable til you take it. Im used to pre-workout’s with heavy caffeine, so when i first took it i really didnt feel anything. Only to find out I could go further and harder which is what we all want. Equals gains which i got from 165 to 193 in 4 months. Along with healthy diet and two hours a night weight training hard! Enjoy you will not be disappointed! Only thing I do different is mix slowly with a 12oz redbull to get in the zone fast, and slowly cause it foams alot. No shaker bottles unless you want to wait 30 minutes for it to settle! Best product forsure just needs more caffeine, probably around 300>mg forsure.

    Transparent Labs PreSeries BULK Supplement Facts

    Overview

    PreSeries Bulk was designed to be the most exceptional bulking pre-workout supplement available with key ingredients backed by published scientifically research for serious athletes and bodybuilders who want to gain size and increase muscle mass.

    Directions

    Take PreSeries Bulk 20-30 minutes prior to your workout. We recommend mixing 6-8 fl oz of water with ½ scoop (to assess tolerance) and mixing 12-16 fl oz of water with 1 full scoop.

    Warnings

    Only use as directed. Keep out of reach of children. Speak with your physician before use if you have a medical condition, are taking medication, or are pregnant or nursing.

    Featured Ingredients

    Citrulline Malate – Citrulline malate is used instead of L-arginine because it absorbs better, increases arginine levels greater than arginine itself, and is up to twice as effective as arginine at raising nitric oxide levels.

    Beta-Alanine – Supplementing with beta-alanine increases muscle carnosine levels to delay the onset of muscular fatigue during intense training sessions. Beta-alanine combats fatigue for greater endurance and increased lean muscle mass.

    BCAA 2:1:1 – PreSeries Bulk contains 2,000mg of leucine and 1,000mg of valine and isoleucine each per serving. These crucial BCAAs aids metabolism during workouts, promotes muscle growth, and provides anti-catabolism benefits.

    L-Norvaline – Norvaline, an isomer of the BCAA valine, reduces arginase activity in the body, increasing arginine and nitric oxide levels. Norvaline provides a stronger and longer NOS response, enhancing muscular pumps and strength.

    Caffeine Anhydrous – Caffeine anhydrous is a pure, natural stimulant that enhances focus, reduces fatigue, and significantly increase performance capacity. PreSeries Bulk contains a moderate amount of caffeine to provide all the benefits without interfering with natural thermoregulation.

    Q. Does PreSeries Bulk Contain Any Creatine?

    A. No, PreSeries Bulk does not contain any creatine. Moderate doses of caffeine tend to negate the benefits of creatine. PreSeries Bulk contains 180mg of caffeine anhydrous, which is why it is creatine free. For a pre-workout solution that includes creatine, consider taking a look at PreSeries STIM-FREE.

    Q. Does PreSeries Bulk Contain Any Banned Substances?

    A. No, PreSeries Bulk contains zero illegal drugs of any kind. If you are going to be subjected to rigorous drug-testing procedures, it is recommended you show your coach or administration the supplement facts panel.

    Q. Can I Stack PreSeries Bulk With My Other Supplements?

    A. PreSeries Bulk can be stacked with other stimulant-free supplements, such as creatine powder or protein powder. Do not combine PreSeries Bulk with other sources of caffeine, including caffeinated beverages such as tea, coffee, or soda.

    Q. What Makes PreSeries Bulk Unique?

    A. PreSeries Bulk is specially designed to support lean muscle growth. It includes a testosterone complex and also helps to support fat loss with its thyroid support complex. PreSeries Bulk contains a transparent label with no fillers, additives, or banned substances.
