I've tried many Test suspensions, and LSP's is the worst. Their winny is also just as bad. I've used their entire line. Every other product was great, but the Test Susp. barely draw the Test Susp. out with a 18 gauge needle. It's insane. If you take (2) shots of that brand with a 20 gauge you'll have one painful, chillish, hot sweats, insomnia filled week. It's not fun. You can stretch all you want, do all kinds of stupid shit that some think will work with this brand. The particles are too big, and when it's injected your body thinks of it as a foreign substance. It's just natural for your body to put up its defense system and in turn side effects will follow. Massaging, heat, etc..etc. works with a few other substances, but not with this item.
