hey Bro....have ya ever heard of Dermatherm? its supposed to be the newest topical fat burner out right now. burns fat without losing the muscle, i have read some research on it and it seems quite good, im not sure it will promote muscle growth, check it out at Primordialperformance.com, they also have testimonials on all their products, i have dermacrine and dermacrine sustain for my upcoming PCT, but have not tried the Dermatherm, hope this helps
