TBJP MPS Max 440g, Essential Amino Acid Intra-Training

TBJP MPS Max is a premium intra-workout amino acid formula combining EAAs with patented MPS-enhancement and performance compounds. Each 22g serving delivers EAA blend 10g, PeptoPro (hydrolysed casein peptides) 2500mg, hydrolysed whey protein 2500mg, PeakO2 1000mg, Velositol 1000mg, Aquamin MG 500mg, Aquamin F 500mg and AstraGin 50mg. The 440g tub provides 20 servings.

The 10g EAA blend provides all nine essential amino acids at the full dose required to saturate the MPS signalling threshold. PeptoPro at 2500mg is a patented di- and tri-peptide hydrolysed casein fraction with superior gut absorption kinetics versus intact proteins - studied for intra-workout MPS augmentation. Hydrolysed whey at 2500mg adds a second fast-acting protein fraction. Velositol at 1000mg is a patented chromium-amylopectin complex that is studied to amplify the muscle protein synthesis response to amino acids - effectively increasing the MPS stimulus from the same EAA dose. PeakO2 at 1000mg targets aerobic capacity and time-to-exhaustion. AstraGin at 50mg is a patented absorption enhancer. Aquamin MG and Aquamin F are marine mineral complexes providing magnesium and calcium from seaweed.

MPS Max is the most scientifically loaded intra-workout in the TBJP range. Where TBJP EAA & Hydration delivers amino acids and basic electrolytes at 16p per serving, MPS Max adds Velositol to amplify the MPS response, PeptoPro for faster amino acid delivery, and PeakO2 for the aerobic performance side - a materially different product for a different training priority.

MPS Max suits advanced natural bodybuilders in hypertrophy phases who want to maximise intra-workout MPS signalling, competitive athletes running structured programmes where recovery between sessions is a limiting factor, and anyone who wants more than amino acid delivery from their intra-workout. It is not a budget EAA product. Contains milk (hydrolysed casein and whey).

Frequently Asked Questions

What are EAAs and why take them?

EAAs (essential amino acids) are the nine amino acids your body cannot synthesise and must obtain from food or supplementation: leucine, isoleucine, valine, lysine, threonine, phenylalanine, methionine, histidine and tryptophan. TBJP EAA provides all nine in a leucine-led ratio in every serving - useful through training, between meals, or when training fasted.

When should I drink EAAs around training?

Sip one serving (around 11g in 500ml of cold water) through training. EAAs are particularly useful for fasted training sessions and on cutting plans where total daily protein is tight. They are light on the stomach and refreshing through long sessions. Can also be used between meals.

Can I stack EAAs with creatine or pre-workout?

Yes - EAAs stack cleanly with creatine, pre-workout and hydration. Many lifters mix their 5g daily creatine straight into the EAA shaker, or drink EAAs alongside their pre-workout in two separate bottles. Continue creatine daily at 3–5g and use EAAs on training days or fasted mornings as needed.
