been using mostly slin pin for 10 years or so never any kind of issue at all. 8/10 times don't even feel it at all.
I inject often, that's probably 2000+ shots
28g x 1/2" 1ml
SQ and IM but mostly IM these days as it slightly less finicky
SQ used mostly in lower stomach and hips at front of thighs, no troubles (again we are all different)
IM almost everywhere else and right now I'm out of shape and carrying probably an extra 20lbs of fat.
IM shots straight in at 90deg with enough pressure to cause slight dimpling of the skin
IM Most used spots - Side Delt, Outside Tris, Ventro Glute and Calves. Less used - Pecs and Bis.
Delatestryl I warm bottle on an electric heating pad Most UGL's these days don't need warming but it does flow better than not so I usually do.
Used to backload 10 at a time especially if using more than one compound, mostly to have preloaded as I travel a lot.
I don't backload anymore unless using more than 2 compounds, sharpness stays good despite poking 2 vials.
Personally I would never rub to disperse a bolus, IM or SQ, I feel that does more damage.
Same BW levels as deep IM.
Only time I go with bigger Pin is when using more than 7cc a week or when frontloading,
even then I'd often do more than one slinpin shot in a day rather than use a harpoon.
All good hygiene practices still apply IMO, some guys get a little slack on this with short pins for some reason. I must admit I slack on that with peps, hcg (SQ) and such but not oils.
