Even a minimal skin fold appears sufficient according to a nurse and a parent of a diabetic child. With the upper arms I skip the pinch entirely and just push a 6 mm needle straight in, or an 8 mm one at a slight angle. Thighs offer another workable location. Certain peptides besides one mentioned can be given intramuscularly, and some clinics administer another compound that way as well. One peptide may sting more by that route because of its copper content, though it has not been tried. The same compound given intramuscularly carries an anecdotal risk of strong reaction.
After beginning the new peptides in June, the usual midsection pinch for injections became nearly impossible. I have always carried love handles, so it is odd to watch them shrink away. Weight dropped from 185 to 168 pounds and the abdominal fat layer is now so thin that finding fresh spots is difficult. Blood sometimes appears on withdrawal where the old handles used to be. Glutes are suggested as an option but reaching them while seeing the site feels awkward. Other compounds are also in the mix but the main one is staying because results have been strong.
