I got 1 vial of the Pharma Mix 2 during a promo and used it at the end of a 10 week cycle I transistioned from GenexPharma Profinex 200 which consist of 100mg tren ace and 100mg test prop which I really like the Profinex 200 I just wanted to see if there was gonna be any difference in product quality. Switching over was flawless I noticed there was much less pip if none at all using the Mix 2 at 1ml if using more than 1ml in one injection site it might have a little pip to it. I feel this mix is very well dosed and potent as all the same signs of good tren were there when I switched. Day and night sweats, shorter temper, strength and libido were at a max and an overall great sense of being. Before I switched I was having tons of insomnia due to the tren after I switched the insomnia was still there and just as bad so I really feel this product to be of great quality. Good luck and enjoy the awesome products you got!!!
