ive used quite a few. purchase peptides, evolution peptides, pep wharehouse, geopeptides ect. and i can give some honest feedback. purchase used to be solid, like a year-year and a half ago. there quality went pretty far down and feedback and reviews seemed to produce more unsatisfied customers than satisfied customers recently. im sure alot of their peptides are of decent legitimacy but id personally be wary of their liquids. their exemstane was good, very powerful when i used it 2 years ago but their clomid was under-dosed and their torem was bunk. evolution was very good but can be hit and miss depending on the product. cilais was great, exemstane was good, their prami was bunk... straight bunk. dose 2mg and felt nothing really then popped a cap of .5mg from noble and had to go home from work sick i was so sick. white as a ghost. geopeptide is currently my go to research company. every product ive used from them is potent and legit. cjc-1295, mk-677, igf-des igf-lr3, cialis, exemstane, clenbuterol all good and dosed accurately ime. and you can usually find a bogo coupon code from their fb page. so thats my rec atm.
