Pre/Intra/Post Workout Frequently Asked Questions

What do pre workout supplements do?

Pre Workout supplements combine amino acids like arginine, leucine and citrulline malate which can help with blood flow, delaying fatigue and muscular endurance with stimulants like caffeine which provide an adrenal (energy) boost. They have two benefits, one is a short term gain in strength and focus, so you can lift more in the gym and train longer. The other is a longer term benefit in strength and endurance which comes from the amino acids and other non stimulant ingredients. We offer a large variety of pre workouts, some are "stimulant free" with others being pure stimulants. We suggest you spend some time reading up on the different varieties we offer to determine which best suit you.

Are pre workout supplements bad for you?

A sensible person once said "everything in moderation", this is a good way to look at pre workouts. Pre Workout supplements generally contain the same amount of caffeine as a double or triple shot coffee, and they often have other stimulants which make this effect stronger. Having these too often and / or too late in the day can lead to issues like insomnia. This really depends on the individual though as some people are heavily affected by a cup of coffee, others happily coffee before bed. At Bulk Nutrients we recommend pre workouts in moderation. They work best if you don't have them everyday and if one scoop works fine, don't have two for the hell of it!

How long do pre workout supplements last?

The effect of Pre Workout supplements depends a lot on the stimulant combination. Caffeine itself has a half life of 5 hours. Dosing also effects this too, a larger dose will take longer to clear from the body. Depending on your sensitivity, we usually don't recommend pre workout is used by people who train late in the evenings.

When to take pre workout?

Pre workouts seem to work best when they are taken 30 - 60 minutes before training starts. Again, this differs person to person and is affected by how much food you have eaten. A full stomach will slow this absorption down, while having pre workout on an empty stomach will mean it comes on a little faster.

Does pre workout help me get stronger?

Yes, however there are two effects here. The first is the short term "acute" benefits from the stimulants like caffeine which can improve reaction time and strength after you have the product. This means your lifts in the gym will be a touch better than without them. The second affect is the longer term benefit you get from using amino acids like arginine, creatine and citrulline malate in the pre workouts regularly, there is plenty of evidence for these helping build strength, endurance and muscle size over time.

What are BCAAs?

BCAAs (Branched Chain Amino Acids) are 3 key amino acids (Leucine, Valine and Isoleucine) found in protein sources and in "free form". These are considered the most important amino acids for building muscle and assisting recovery.

Most protein sources contain BCAAs however many people like to take BCAAs additionally in "free form". In this form they are pure Leucine, Valine and Isoleucine which are manufactured as separate compounds from a fermentation process. In isolation they can have an effect on energy levels and can help reduce delayed onset muscle soreness (DOMS).

When to take BCAAs?

BCAAs are best taken during or directly after training. It is directly after training that they are most popular, however some users find that sipping them while training means they can sustain their energy levels better in longer sessions.

What do BCAAs do?

BCAAs help build muscle and improve recovery time. They can also help reduce muscle soreness after a session, making a large difference to DOMS (delayed onset muscle soreness) the soreness experienced the day or two after training.

Do BCAAs work?

Yes, they have been proven to work for delaying soreness and improving recovery, however the best question to ask is "can I get the same affect from taking protein?" or "are BCAAs good value compared to just having more protein"? In many cases you can get the same effect, which is a sensible case against BCAAs - particularly if you are trying to get maximum value for money from your supplement usage. In our opinion BCAAs are great when you want to sip on something in the gym to help prolong your session, but after training we think nothing beats a protein shake - or a more complete source of free form amino acids like Future Whey.

What do BCAAs do for muscles?

BCAAs help build muscle, reduce recovery time and reduce muscle soreness.
