At Anabolic Designs we pride ourselves on making formulas that are cutting edge and focus on quality over cost. We make formulas we’d want to use ourselves and always strive to meet new challenges.

BullK- Powered by Bulbine Natelensis
Bulbine Natalensis is the central engine powering the BullK matrix. This potent and cutting edge herbal dietary supplement has been shown to elicit serum testosterone increases of up to 347% over baseline and simultaneously reduce estrogen and prolactin by more than 39% - making it the absolute king of the all-natural hormone boosters.
We have worked overtime to ensure the best possible ingredients are sourced; high grade Bulbine Natelensis of the correct sort is only available in very limited supplies of which we have one of the only confirmed sources. Before you choose a Bulbine-backed product ask yourself if the company offers their COA and lab-tested graphs to prove their quality???
The graphs below might not mean much to the non-chemists among us, but we always provide these so you know you can trust our raw materials with your health and physique! You work hard in the gym why compromise on quality out of it???

BullK- Formula explained
BullK Usage :
For best results users of BullK should aim to consume 2g of protein per lb of bodyweight so a 200lb male should look to ingest around 400g of protein per day. Users Under 220lbs should take 2 capsules of BullK per day with an evening meal, users over 220lbs should take 4 capsules with an evening meal.
Anabolic Designs Offseason Mass Stack – BullK and Ravenous .... The recipe for Mass Construction!
To ensure nutrient uptake is optimal and users have the appetite to ingest such vast amounts (2g per lb of bodyweight) of protein BullK should be stacked with Ravenous as part of the Anabolic Designs Offseason Mass Stack.
For continual physique development cycles of the Offseason Mass stack are suggested for 4-12 weeks followed by the Transform stack (Tauro Test and Shredabull) for 4-8 weeks to solidify gains and reduce any additional body fat gained during the Offseason phase. These two stacks are tailored to ensure maximum muscle mass, strength and performances are achieved whilst keeping healthy and looking like an elite athlete all year round!!
“ Used for 2 weeks so far, trained solid, increaded protein and carb intake dramatically, gained around 2 pounds (natural progression from the food and training intensity). No real strength increase. Hyped up waste of money, may as well take tribuls. ”

“ In response to Gurgit - no gains after 4 weeks use - training and eating perfect - is a poor product. If it only works for 8 weeks, why not sell the full 8week cycle - oh yeh that would be 80quid. What a wasteeee ”
