Quite high quality production This supplier is legitimate. I 'm running a fast rapid ester blast right now, so I can't comment on the deca yet. The dianabol did it's job for me at 20 mg regularly, I'm pretty cautious with my dosages, I may be able to bump it up a little, but why? It was working as expected. I'm going to wrap myself up with it at the top. The mix of tests is potent. What's on the box is certainly in the bottle. After a layoff due to covid19 closing the gyms, this stuff got me back on track easily. Power has risen rapidly, weight has marginally increased, but there is definition and complete muscles. I run it on EOD for a weekly total of 500 mg. When I inject into my delt, some acne on the back and shoulders (which I'm prone to) and mild pip (short ester has always been a little bit me in that area). I couldn't have been happier overall. I suggest giving them a go if you haven't tried sportlifepower.biz yet. You're not going to be disappointed. Verifiable product codes are always a huge advantage.
