#5: Alpha Lion - Superhuman Pump
The Alpha Lion Superhuman Pump is the successor to the popular Komodo Pump. Alpha Lion relies on 3000 mg of HydroPrime® with 65% concentrated glycerol in the Superhuman Pump. The manufacturer of HydroPrime promises to prevent the common problem of powder clumping due to glycerol‘s water-binding properties. In addition to HydroPrime®, the pump formula includes 8000 mg of citrulline malate and 150 mg of the patented ingredient S7. This is a blend of seven plant-based ingredients designed to increase nitric oxide (NO) production in the body, thereby enhancing blood flow and oxygen supply.
Additionally, Superhuman Pump contains 3500 mg of beta-alanine, which delays muscle fatigue, and 600 mg of lion’s mane, derived from the mushroom Hericium erinaceus, known for its potential neuroprotective and cognitive-enhancing properties. Other ingredients known for their nootropic effects include AlphaSize® (300 mg), a highly bioavailable form of choline, and Huperzine A 1% (300 mcg). The formula is completed with the electrolytes sodium, potassium, and magnesium.
Product Features:
- Relies on high-quality branded raw materials
- Pump + Focus-Formel
- Available in delicious flavors.

#4: Evoled Nutrition Agmatine 90 Caps
As the name suggests, this is a capsule product containing just one active ingredient: agmatine sulfate. However, this ingredient is truly powerful and is referred to as ‘super-arginine‘ – not only because of its structural similarity to arginine but especially due to its significantly stronger effects, as nitric oxide production is stimulated to a much greater extent than with arginine. Since agmatine falls under the Novel Food Regulation within the EU and is therefore not officially marketable in Germany, it is primarily found in US products.
In addition to its powerful pump effect, agmatine also has nootropic properties. Another benefit is its pain-relieving effects, as well as improved recovery. Per capsule, you receive 500 mg of agmatine, which also works perfectly as a stack for your pre-workout.
Product Features:
- 500 mg of agmatine per capsule
- Perfectly suitable for stacking

#3: Levrone – Shaaboom Pump (US)
The US version of the Levrone Shaaboom Pump is expectedly much stronger than its EU counterpart. Additionally, it contains caffeine again, but not 200 mg like in the EU version, but double that amount, namely 400 mg. However, the main focus is on the 2000 mg of AgmaMAX®, a patented form of agmatine sulfate. Since agmatine is not officially marketable in Germany, this vein-bursting ingredient is mainly found in US products. Due to its structural similarity to arginine, but with a significantly stronger effect, agmatine is often referred to as ‘super-arginine.’
Along with agmatine, 2000 mg of citrulline malate and 2000 mg of arginine AKG (arginine alpha-ketoglutarate) provide the necessary support for pumps. CarnoSyn® is another branded raw material included, which is a particularly high-quality form of beta-alanine. The effect of the non-essential amino acid beta-alanine acts directly within the cells, significantly increasing the carnosine levels, which leads to a reduction in pH levels, thus diminishing the negative effects of lactic acid on the muscles. As a result, muscle fatigue sets in later, allowing for more intense training sessions. In addition, Shaaboom Pump contains creatine monohydrate, tri-creatine malate, which includes three different creatine molecules connected to a malic acid molecule, as well as creatine HCL.

#2: Hammer Labz – Steel X Pump
Hammer Labz delivers the Steel X Pump, a pump booster that particularly stands out due to its inclusion of agmatine sulfate (1500 mg). This is a metabolic product formed through decarboxylation – that is, by removing a carboxyl group – from the amino acid L-arginine. The amino acid promotes the release of nitric oxide (NO) in the body, which has a vasodilatory effect. As a consequence, this means that L-arginine ensures increased blood flow to the muscles during training. However, since agmatine has a significantly stronger effect, it is often referred to as ‘super-arginine.’
Additionally, agmatine acts as a neurotransmitter. By blocking NMDA receptor channels and other cation channels, it lowers pain perception, which in turn allows for harder and more intense training. Moreover, agmatine has antioxidant properties and reduces recovery time. Within the EU, agmatine falls under the Novel Food Regulation and is therefore not officially marketable in Germany. Consequently, agmatine is not found in EU boosters.
After this brief excursion into agmatine, we certainly don’t want to overlook the other ingredients in Steel X Pump. In addition to the mentioned agmatine, it also contains a good 6000 mg of pure L-citrulline, 3000 mg of beta-alanine, which counteracts muscle fatigue, 2000 mg of arginine AKG (arginine alpha-ketoglutarate), a form of arginine with very high bioavailability, 2000 mg of GlycerPump® (65% glycerol), 500 mg of arginine in nitrate form, 500 mg of beetroot extract, 150 mg of norvaline, and pink Himalayan salt.

- With Agmatin

#1: Skull Labs – Angel Dust Pump
Contrary to what the name might suggest, the Angel Dust Pump from the Polish supplement manufacturer Skull Labs is not a stimulant-free pump booster. A quick look at the label reveals almost the entire range of (hardcore) stimulants. In the Angel Dust Pump, we find 300 mg of caffeine, 200 mg of Eria Jarensis, 700 mg of beta-phenylethylamine, and 50 mg each of hordenine, higenamine, and N-methyl L-tyramine HCL. Notably, 100 mg each of DMHA and DMAA stand out. Together, these ingredients guarantee a massive energy boost, euphoric workouts, and laser-sharp focus. There’s no more stimulants than this!
This is complemented by substantial dosages of the pump ingredients citrulline malate (6000 mg) as well as arginine AKG and agmatine (each 2000 mg), which also explains the naming of the booster. Skull Labs combines a hardcore booster with the most effective pump ingredients, bringing together the best of both booster worlds. We have often criticized the lack of pump and the insufficient vascularity in our hardcore booster reviews – this can definitely be ruled out here. This also results in a hefty serving size of 17.5 grams per serving. In addition to the stimulant section and the pump ingredients, Angel Dust Pump also contains beta-alanine, taurine, creatine nitrate, choline bitartrate, GABA, and for thermogenesis and to accelerate fat metabolism, 2 mg each of yohimbine bark extract and alpha yohimbine.
