Real feedback from real customers across the UK
- ★★★★★"Thank you Anthony!! You are so helpful and really responsive! You offer genuine insight and advice!! I’m so grateful for your assistance and prompt support!!!"
- ★★★★★"First time I've tried this company and product. Getting the product was hassle free. Got good gains with no bloating which I've had before from similar products. Will be a returning customer."
- ★★★★★"Great for the price. Can confirm its legit ibutamoren and have used this for the past 1-2 years. It's great for bulking research; increased hunger makes getting extra calories in a breeze, improved sleep helps with recovery, water retention adds leverage to lifts and gives a great pump, increased gh and igf1 production definitely helps with tendon and joint injuries massively (at least for me since I'm quite injury prone). For a bulking research protocol I usually run 10mg-12.5mg for the first 1 week, then transition to 20mg-25mg for 6 weeks, then back to 10mg-12.5mg for the last week to taper off (just helps avoid sudden loss of lifting strength and recovery capacity). Would 100% recommend to anyone who's been training naturally for a few years and is thinking about these research compounds."
- ★★★★★"Got to say the pumps and recovery from this MK677 has been amazing. Weight has roughly stayed the same but composition has visibly improved. I'm approaching 12 weeks of research now and for me the improvements to my sleep have been worth the price alone as I often go to bed the wrong side of midnight despite starting earlies the next day"
- ★★★★★"This is my second purchase of Cardarine and I can't recommend it enough. After my first cycle I lost 3.5kgs in 6weeks. Of course my diet was strict and cardio was on point, but the cardarine had a huge impact on the rate at which I lost fat and my overall stamina. Extremely good value for money. Couldn't be happier."
- ★★★★★"When it comes to quality this product stands at the top of line. I’ve been following a largely carnivore/low sugar regime for 6 years now and combined with this product it really does works wonders!! Never disappointed with the mental and physical gains this golden stack delivers 💪💪"
